Air Conditioning

When the temperature rises, our ability to work suffers and vital equipment can develop faults.In order to prevent these problems, Andrews Sykes offer a wide range of temporary, portableair conditioners, with or without air cooled external heat exchangers.

The basic principle of air conditioningAn air conditioner is a closed refrigerant system, comprising of an evaporator, a compressor, a condenser and an expansion valve (or capillary), which are all connected to each other withrefrigerant piping. Refrigerant gas is circulated within the system in the direction shown in thefollowing drawing.

The indoor unit, which is usually installed in the room to be cooled, contains the process where the refrigerant evaporates within the cold element (evaporator). This evaporation iscaused because the refrigerant has a very low boiling point of -40.8ºC at atmospheric pressure.To enable the evaporation a rise in temperature is necessary. This rise is supplied by the air ofthe room which is to be cooled and in which the evaporator is situated. As air is passed overthe evaporator the air temperature will drop and therefore enable the room air temperature tobe reduced.

The compressor draws the vapour refrigerant and reduces the pressure in the evaporator.Because of this pressure reduction the refrigerant evaporates. The vapour which is drawn bythe compressor is then compressed. The pressure and temperature of the gas rises as it iscompressed into the condenser, where the warm gas is cooled down to the condensationtemperature of the refrigerant. Subsequently the vapour returns back to liquid again. In thecondenser the process is almost directly opposite to the evaporator. The condensor requirescooling otherwise the temperature and gas pressure will rise too high. For this cooling processeither water or air can be used.

The vapour which has now returned to liquid again is now passed through the expansion valve (or capillary) to the evaporator. Because of the narrowing of the pipework the pressuredecreases and the refrigerant evaporates once more. To enable this evaporation the warm air isneeded and so the circuit is closed.

The Operation of portable air conditionersAndrews Sykes offers 3 principle types of portable Air Conditioners. These are as follows:

Exhaust tube unitsIn ET models both the evaporator and condenser are positioned within the room unit. The majority of the air that is passed through the unit is directed over the evaporator andreturns back into the room, as cooled air. A smaller volume of air is passed across thecondenser to cool the refrigerant gas. This air needs to be removed from the room as itbecomes hot. An exhaust tube is used to remove this hot air via an opening in the room (usuallythrough a window). In some cases the exhaust tube may be positioned into a false ceiling void,advice should be sought before using this system.

Split type units (refrigerant)These are models similar to the PAC8 and PAC14, such units are supplied in 2 parts, a roomunit and a condenser. The room unit placed within the area to be cooled comprises of anevaporator and a compressor. The room air enters the unit and once passed across theevaporator is returned into the room as cooled air. The external unit which is connected to theroom unit by a flexible pipe, contains the condenser which needs to cooled by ambient air,therefore the external unit needs to be positioned outside of the room to be cooled. Typicallythe condenser is hung from a window.

Split type units (water)These units are the PAC22, PAC15 andPAC60, such units are also supplied in 2parts, a room unit and a heat exchanger. The principle in operation is very similar to the above. The major difference is that thecondenser is placed within the room unit andcooled by water. The water is then circulatedto the external unit (heat exchanger) viaflexible pipes before returning to the roomunit. The system is totally sealed and requiresno further water once the unit is in place. The main advantage of this system is that the connection pipes can be extended - up to 30m - allowing the heat exchanger to bepositioned away from the room unit.

Air Conditioning

Calculating the cooling capacityrequired and choosing the type of air conditioningThe heat load for each room can varyconsiderably. This depends on the number of lights, the number of people, glass areafacing the sun, and the presence ofcomputers and other equipment. It istherefore essential to determine the capacity correctly.

Rules of thumb for an approximation of airconditioning load are:

■ Normal Modern Offices: ± 46 W per m3

■ Portable Buildings: ± 57 W per m3

■ Tents/Marquees: ± 95 W per m3

NB: Multiply kw by 3412 to obtain Btu

In addition to the type and size of the area to be cooled consideration must be given toany appliances that generate heat in the area.Such appliances are listed below along with the approximate heat emission thatthey generate.

■ Personal Computer ± 150w

■ Laser Printer ± 500w

■ Photocopier Standby ± 200w

■ Photocopier In Use ± 1000w

■ Fax Machine ± 500w

■ Coffee Machine ± 800w

■ TV/ Video Screen ± 50w

Obviously, the Andrews Sykes specialists will be glad to work out an accurate coolingcalculation for you.

Selection and installation of your portable air conditionerTo select which type of temporary air conditioner you must first consider the capacity of the unit and the possible alternatives to remove the condenser heat.

A room without outside walls or windows often means that a standard PAC (split) unit can notbe used. If an exhaust tube can not be vented into a ceiling void or out of the room the onlyalternative may be a water-cooled PAC unit. Again, if it is not possible to position a heatexchanger within 30m of the room unit other alternatives such as a chillier, evaporative coolersor cooling fans may need to be considered.

Before you select your Andrews Sykes portable air conditioner we suggest the following issues should be considered.

1 The indoor unit (evaporator) needs to be positioned within 1m of a 13amp 230v socket and located in a manner to avoid any obstruction to the airflow.

2 If you are to use a PAC type unit the heat exchanger (condenser) will need to be positionedoutside of the building or in a very well ventilated area that can withstand the heattransferred from the room being cooled. Condensation is discharged from the room unit to the heat exchanger where it is allowed to drain to the outside of the building. If the heatexchanger is placed within the building a separate means of discharging the condensationneeds to be provided.

3 When using a PAC unit it is always advisable to position the heat exchanger away fromdirect sunlight or any position where its operation is likely to cause disruption. The heatexchanger can only be positioned within the distance specified by PAC line length. Alwaysaim to keep the PAC line length to a minimum.

4 Always ensure that the electrical supply to the unit is adequate and that the operation of the unit will not cause any problems to other sensitive electronic equipment.

Evaporative Coolers

There are many applications where it is impossible or impractical to use portable airconditioners. In such cases an alternative may be the use of an evaporative air cooler. Often used where access to an external source is unavailable, the Andrews range of standalone evaporative air coolers are an ideal solution to uncomfortable conditions.

The evaporative concept is designed to cool fresh air through the process of naturalevaporation by drawing air across a wet filter and providing a refreshing air flow. As the airpasses the wet filter, a drop in temperature will be experienced, although the overall roomtemperature will not be reduced. The unit will provide a localised comfort cooling zone.

Evaporative units are required to be filled with fresh mains water which evaporates andtherefore needs to be refilled on a regular basis. The water is evaporated into the air within the room, so it is essential that the room is well ventilated at all times to prevent condensation.These units should not be used in areas that contain delicate materials, electrical equipment orother products that may be affected by the rise in humidity.

The Andrews Sykes range of evaporative coolers do not require any installation and do not haveany external units and therefore can be simply plugged in, switched on and operating withinseconds once they have been filled with water.

Chillers

When the need for a low temperature application arises, the Andrews Sykes range of fast chillunits have been developed to provide temperatures below -10ºC. The range comprises of 3models which can be used in a similar configuration to the water cooled PAC units.

Each of the models comprises of 2 parts - a room unit, which must be placed within or ductedinto the area that requires cooling, and an external heat exchanger. The room unit whichcontains the compressor and evaporator is linked via 2 x 32mm diameter flexible hoses to theexternal heat exchanger. In their standard configuration these flexible lines are supplied inlengths of 15 metres and can be extended up to a maximum of up to 30 metres.

Although larger in size than most PAC units the fast chill units are still portable and can be putto work quickly and with the minimum amount of installation. Each model incorporates aprogrammable controller which can operate within ±0.5ºC.

Applications for portable chillers

Calculating the cooling capacity required and choosing the correct model

Due to the many factors that must be considered when selecting a unit for low temperatureclose control applications, we recommend that a full site survey is carried out by an AndrewsSykes specialist. We can advise not only the best unit for the application but also the bestmethod of installation.

Selection and installation of your portable chillerThe units are portable and can be delivered and installed within a very short period of time. Thelarger units require a 3 phase 415v electrical supply and due to the physical size and weight of theunits special consideration should be made for the positioning of both the room units and the heatexchanger. The connection pipes between the room unit and the heat exchanger are water filledand therefore no external refrigeration connections are required.

Chiller Units

High capacity of fluid chillersThe Andrews Sykes range of high capacity fluid chillers have been developed to provide a fastand efficient solution for many applications that require high volumes of cooling capacity. Inthe standard format fluid chillers can provide cooling water to production processes or tobypass/assist permanently installed chillers. When used along with our wide range of airhandlers and fan coils, fluid chillers provide high capacity air conditioning for a wide rangeof applications.

The standard range comprises of units up to 500Kw in capacity and can be used in parallel toachieve higher capacities. Larger units for long term applications are also available. A wide range of temperatures can be provided, with units able to achieve water temperaturesbelow -10ºC. Heat pump versions are available on some models to provide not only cooling butalso heating.

All of the units in the Andrews Sykes fluid chiller range are air cooled and do not require apermanent water supply. The chiller unit must be placed in a well ventilated area that is able toaccept the heat dissipation from the area being cooled. Ideally chillers should always be installedon the exterior of the building, where the ambient air can provide cooling.

Each of the units contains a heat exchanger, condenser, control system, compressor andcirculating pumps. Mounted on robust base plates complete with lifting facility, the units can betransported and positioned with the minimum of disruption. The water connection on the supplyand return pipework is normally achieved with quick action couplings, removing the need forcomplicated pipe connections. The chillers use flexible hoses to provide chilled water to eitherthe air handlers or the clients own system.

The operation of high capacity fluid chillersAndrews Sykes offer 3 principle methods of using fluid chillers. These are as follows:

Air conditioning applicationThis is where a fluid chiller (or chillers) are connected to air handling units (AHU) or fan coils viaflexible pipework. The chiller provides chilled water to each of the fan coils or AHU, which isthen pumped through a coil over which the room air is passed. As the air passes over the coldcoil the air temperature will drop, the drop in temperature will depend on several factors suchas air flow, air temperature and humidity. Each time the air is passed over the cold coil a similardrop in temperature will take place, this will enable the room temperature to be controlledwithin specified criteria. As the warm air passes over the cold coil the chilled water temperaturerises and therefore returns to the chiller as warm water, the water is then chilled again andreturned to the air handlers or fan coils and so the circuit is closed.

Some fan coils have thermostatically operated valves which open and close in relation to theroom temperature, bringing in chilled water when required and remaining closed when thedesired temperature is achieved. The chiller operates as required depending on the watertemperature, although the circulating pump operates at all times.

The normal installation has the fan coils units installed within the room that requires cooling, orAHU installed outside of the room with the air ducted into the room and returned via heavy dutyflexible ducting. However in some circumstances it is possible to fit flexible ducting to the fancoils and in others it is possible to install the AHU within the room that is to be cooled.

With heat pump versions of the fluid chillers it is possible to generate hot water and thereby usethe fan coils and AHUs as heaters rather than air conditioners. In applications that may requireheating at night and cooling by day it is possible to fully automate this process.

Process applicationsThis system is often used where a product requires cooling but due to its nature or consistencycannot come into contact with the refrigeration process. Such products include oil, volatilefluids and food products. Andrews Sykes overcome this problem by using a fluid chiller inconjunction with a process heat exchanger (normally a plate type).

The fluid chiller produces chilled water which is then circulated through the heat exchanger andthen returned to the chiller in a closed circuit. The product that requires cooling is also circulatedthrough the heat exchanger but is kept separate from the chilled water at all times. As the productpasses through the heat exchanger it is cooled by the chilled water that is being circulated at thesame time, this enables the product’s temperature to be reduced to the specified level. As thechilled water passes through the same heat exchanger its temperature will rise, as it is effectivelybeing heated by the product. The water will then become warm as it is returned to the chiller tobecome chilled once more and so the circuit is closed.

The connection between the heat exchanger and the chiller would normally be through flexible pipeswith quick release couplings. The temperature can be controlled by the control system within thechiller itself. This application can be easily adjusted to suit most environments.

Breakdown / recovery / assist applicationsThis application can normally be used where an existing chiller system has broken down, isrequired to be taken out of operation or needs additional cooling assistance. Such situationsmay be due to building modifications, maintenance shut downs, main plant failure or abnormalheat loads within the building.

An Andrews Sykes fluid chiller can be connected into the clients own pipework system usingflanged connections which will be fitted with isolating valves and quick release pipe adapters.Flexible hoses would then connect onto the pipework and run to the temporary chiller.

Where possible the client’s own pipework, circulating pumps and controls continue to be used.In some situations the circulating pumps within the chiller may be adequate to cope, or canassist the existing pumps.

Careful consideration must be given to the effect of increasing the flow rate of the chilled water,if the temporary chiller is to be used in conjunction with an existing system. Andrews Sykesspecialists are able to advise on the correct sizing and correct use of such applications,however it is vital that details of the required flow rates, temperatures and cooling duty areknown. A full system diagram of the existing installation is also required. Such systems can be used as a semi-permanent solution or as an emergency back up.

Selection and installation of a fluid chillerWhen sizing a chiller for air conditioning applications the same principles should be applied thatare mentioned in the air conditioning section of this booklet. The location of the air handlers, fancoils and chiller does require careful consideration and we would therefore suggest that a sitesurvey is carried out by one of Andrews Sykes specialists.

Process applications and breakdown / recovery applications do require a great deal of calculationto guarantee that flow rates, design temperature and other requirements are met, it is thereforeessential that an Andrews Sykes specialist is consulted about such applications.

In addition to providing the chillers, air handlers and fan coils Andrews Sykes also provide allnecessary accessories and additional equipment. This includes generators, distribution units,cable, flexible hoses, heat exchangers, valves, pipework, adapters, and flexible ducting.

The Andrews Sykes specialist hire team offer a FREE on site survey and advice, together with a delivery, installation and on-site commissioning service. Once the equipment is installed it issupported 24 hours a day, 7 days a week by the Andrews Sykes service back-up from over 30depots nationwide.

Processes This system is often used where a product requires heating but due to the nature of the productit must not come into contact with the boiler circuit. To satisfy this requirement if the boiler isused in conjunction with a heat exchanger, a plate heat exchanger is preferred for this type ofapplication; this will keep separate the boiler flow and the process flow.

Breakdown and recoveryThe Andrews Sykes packaged boiler may be used to maintain hot water and heating flow to existing systems, in the event of planned maintenance to existing plant or fast on sitetemporary installation during breakdown situations.

Humidifiers

H U M I D I F I E R SIn today’s environment of air conditioned buildings containing large amounts of electricalequipment low humidity is often a problem. In addition to causing problems with essentialequipment, dry air also creates a poor working environment, commonly resulting in dry throatsand sore eyes. Where electrical equipment is installed, static electricity is also a problem.

To overcome low humidity problems Andrews Sykes offer portable humidifiers which aredesigned to add moisture to the room air and therefore increase the humidity. The units aresimple to operate and are easily portable from room to room. Each unit requires only a standard3 pin 240v socket to operate from - once filled with water you need only switch the unit on for itto start working.

The humidifiers consist of a rotating wheel which is covered in a sponge type material. As the wheel rotates the material travels through a water tank, the sponge absorbs a quantity ofthe water and continues to rotate. During the rotation a small fan draws in air from the roomand blows it past the moist material. As the air is passed over the material a quantity of themoisture is added to the air thus increasing the humidity in the room. The drum continues torotate and on each pass picks up moisture from the tank and adds it to the air in the room untilthe desired level of humidity is obtained. The only maintenance required is to refill the tank withmains water on a regular basis.

The operation of refrigerant dryersRefrigerant dryers cool air intake considerablyby means of an evaporator section in a closedrefrigeration system. As a result of this cooling,the relative humidity of the air over theevaporator raises to above 100% and watervapour condenses. This water (orcondensation) is either drained into a reservoiror through a hose to a drain, water container ora suitable outside location. The heat generatedin the cooling system condenser is used towarm the returned air to a temperature abovethat of the original intake. Each time the roomair is passed through the dryer a quantity ofmoisture is removed from the air, therefore the

Dehumidifiers

humidity within the room is reduced.Refrigerant dryers are typically positionedwithin the room to be dried and require littleattention whilst in operation.

The operation of desiccant dryersA desiccant dryer uses the hygroscopicproperties of moisture-absorption materialssuch as silica gel or lithium chloride. Thesematerials are impregnated within a rotatingceramic wheel, over which the humid air fromthe room is blown. The hygroscopic materialabsorbs a large percentage of the moisturefrom the air, therefore reducing the humidity in the area. The wheel is left very wet, it thencontinues to rotate slowly and the sectionwhich is saturated with moisture is heatedwith an electric heater, to vapourise the water.This warm and very humid air is then expelledoutside through a length of flexible ducting.As well as being able to place a desiccantunit within a room that is to be dried,desicccant dryers are often used inapplications where it is not possible toposition a dryer, such as hazardous areas or areas with limited access such as pipesand tanks.

Dehumidifiers

Dehumidification with an Andrews Sykesrefrigerant building dryer is up to 75%cheaper than using heating in combinationwith ventilation to dry a room.

Calculation and selection of the correctdehumidifier or dryerTo correctly decide upon the most efficientway of drying an area many factors need tobe considered: temperature, materials, relativehumidity and drying time. This calculation isbest left to the experts at Andrews Sykeswho, armed with a hygrometer andpsychrometric chart, will give you the verybest advice – free of charge – on how to useour units.

BASIC ‘RULE OF THUMB’ SIZING

Refrigerant unitsThese are usually sized taking a typical RH of 75% at an air temperature of 20ºC, theperformance of the unit will vary greatly as the temperature and RH rises or falls. Typicallythe units are shown to be able to keep an areain cubic metres dry, based on the aboveconditions. The dry out area is usually around50% of this as the area is assumed to bealready wet and this moisture needs to be removed.

Desiccant unitsIn general a desiccant unit is suitable todehumidify a room with a volume two timesbigger than the dry air volume produced bythe dryer. A desiccant dryer with a dry airvolume of 1,600 m3/h is suitable to dry a room of approximately 3,200 m3.

Installation of a dehumidifierBefore the installation of a dehumidifier, the roomto be dried has to be sealed as well as possible.This means the room’s windows and doors are

kept closed and gaps and ventilation holes arecovered so that humid air is prevented fromflowing inside from the outside. Plastic covers aresuitable for sealing a room – it is not necessary touse heat insulation!

If one dryer is to be used it should be positionedin the middle of the room. For larger rooms,where more dryers are used, the total roomshould be divided into as many equal sectionsas dryers to be used. A dryer is installed in themiddle of each section to ensure perfect aircirculation. The dryer has to be positioned so itcan blow dry air without obstruction, and its airinlet grill remains clear. If dryers are used inconjunction with heaters (electrical or indirectfired) make sure hot air is not blown in thedirection of the dryers. The condensation fromthe dryer can be caught in a container or a hosecan be used to drain the condensation tooutside or to a drain. In this case the water hasto be piped off vertically otherwise leakages willoccur. Larger Andrews Sykes' dryers removecondensation by means of a condensationpump - a new development in dehumidificationtechnology. This pump allows the condensationto be easily pumped upwards through a windowor down to an outside drain. Due to this newdevelopment it is no longer necessary to emptyand to check the waterbuckets, for exampleduring the weekends and holidays.

Faster drying

For a faster drying process, dryers can beinstalled together with Andrews Sykes ventilationfans. The increased air circulation results infaster moisture evaporation, minimising thedanger of shrink damage from drying out toofast.In some cases the addition of indirect orelectrical heaters may be recommended.

Dehumidifiers

Applications of refrigerant anddesiccant dryersRefrigerant dryers are most commonly usedin the British climate. Dessicant dryers tend tobe only used in the following situations:■ a very low relative humidity is required

(< 40%) ■ the work is being carried out at extremely

low temperatures (< -10ºC)■ a low dew point is essential

(for example tank-coating)■ the unit has to be ducted into the area that

needs drying

A refrigerant dryer uses about one third of theenergy of a similar desiccant dryer, thereforethe obvious advantage (especially on site) isthat it requires much less electricity so thatrunning costs are usually reduced. Adesiccant dryer is more efficient than arefrigerant dryer at about -5ºC.

Typical applications include■ Drying out buildings during

construction / finishing■ Drying out after a fire or flood■ Storage of delicate products that are

moisture sensitive■ Keeping electrical switch rooms dry■ Equipment drying rooms on construction

sites, outdoor activity centres, fire

stations etc■ The drying out of pipework and tanks prior

to repainting / coating

Fire and water damageIn the case of fire and water damageimmediate, fast and professional action isessential to avoid further damage. AndrewsSykes hire dryers, heaters and fans to reducerelative humidity and to ventilate polluted air.Corrosion (HCL) can be stopped; buildings,furniture and inventory can be saved and thusrestoration costs can be minimized.

Building dryingThe most important reason for using buildingdryers is to minimize the total building time bycreating the perfect conditions for painting,plastering, finishing floors and ceilings, wall-paper etc. Andrews Sykes has the right dryeravailable whether you need a building dryerfor a house, a cellar, a safe or a complete utility.

Humidity control during storageIncreasingly, higher demands are made uponthe relative humidity standards for all storageincluding agricultural products, electroniccomponents, sheet steel, food, paperproducts, powders, objets d’art, antiques etc.The list is almost endless.

Cooling and Ventilation Fans

C O O L I N G A N D V E N T I L AT I O N Good ventilation is essential to achieve a comfortable and pleasant working environment.

Dangerous materials can be removed by ventilation, such as paint vapours, dust, weldingfumes, carbon monoxide, carbon dioxide and water vapour. Ventilation is necessary to assure acontinuous supply of fresh air, in addition ventilation is often legally required by the governmentor Health and Safety executive, where certain activities take place.

As well as providing fresh air, fans can also be used to provide and assist comfort cooling inopen areas where fresh air can be circulated, these are often referred to as man coolers orcooling fans.

Ventilation can be achieved in many ways. For example by just opening doors, windows orgrills, or through ducted systems, which are connected to the outside. Sometimes this way ofnatural ventilation is not sufficient or even impossible.

Andrews Sykes can offer a wide range of portable ventilation and cooling fans. These fans caneither blow or suck air and can be used with flexible ducting and dust filters, or just as freeblowing fans.

When the air has to be sucked, it is important that there are enough holes in the room to assurethe supply of fresh air.

Andrews Sykes fans are used for a wide range of applications, such as welding, tank cleaning,sewer maintenance, tunnel construction, painting, digging of polluted ground and demolition. TheFV fans are very useful during the temporary storage of humid or agricultural products. The ASFfans are commonly used to provide cooling in marquees, factories, night clubs, events, exhibitions,sports centres, theatres, conference rooms, shops and many other situations .

Free-blowing fans are often used to supplement heating, drying and air conditioning installations.

For applications in hazardous areas, Andrews Sykes can offer a range of specialist air drivenVenturi ejectors. Manufactured from glass fibre these have no moving parts and are spark proof.Available in 3 ins and 6 ins depending on the required duty.

Useful tips on calculation and sizing for the correct Andrews Sykes ventilation fanThe selection of the correct fan can be achieved with the help of the following calculation:

1. Calculate the volume of the room which needs to be ventilated (width x length x height)

2. Select the recommended number of air changes per hour (from previous chart or similar)

3. Multiply the results of 1 by the result of 2, this will give the required air volume per hour

4. Select the correct fan or fans to achieve this air flow.

ExampleAn engine room which is 3 metres high x 8 metres wide x 22 metres long requires ventilation dueto heat and fume build up. From the chart we can see that the recommended air change isbetween 15 and 30 depending on the intensity of the application. This case is fairly intense so onthe side of caution we can use the ratio of 30 changes per hour .

To calculate;3 m x 8 m x 22 m = 528 Cu Metres x 30 changes = 15,840 Cu Metres per hour

In this situation a model FV900 which has a capacity of 16,500 Cu Metres per hour would be most suitable.

Important note on using ducted unitsIf it is necessary to use long lengths of ducting or involve several bends in the ducting, it mustbe remembered that the resistance in the ducting will increase and the air volume provided willdecrease drastically.

Due to high resistance, certain fans can become useless, although the stated air volume at lowpressure would not indicate this at first sight. The Andrews Sykes FV fans do have highpressure capacity and can be used with several lengths of ducting.

In some applications it may be better to blow rather than suck the air out, or use a combination ofthe two. When used in sensitive environments or handling ignitable fumes, special precautions andequipment must be used. If the application is sensitive, complicated or long lengths of ducting needto be used, you should consult your local Andrews Sykes specialist who will be able to provideadvice on all types of installations.

Portable Heaters

There are hundreds of thousands of portableheaters in use throughout the world in manyand varied industrial, commercial, horticulturaland agricultural applications.

In recent times, the major developmentswithin the design and manufacture of portable heaters have focused on safety,efficiency and durability.

Portable air heaters-which type tochooseBasically there are two distinct types ofportable air heaters-direct fired and indirectfired. There is a choice of fuels, too, includingLiquified Petroleum Gas (LPG), Kerosene, GasOil and Electricity.

Direct FiredA direct fired heater uses an electric fan toprovide combustion air and also the main airflow to give large volumes of heated air. Fuel isinjected into a combustion chamber where it isignited and burnt at a regulated rate mixing withthe main air stream from the fan.

Generally referred to as 100% efficient (basedon net calorific value of the fuel) because all

the heat generated is discharged into the area to be heated. Andrews Sykes direct firedheaters are compact, robust, fully portableand are designed to provide safe controllableheat when and where it is needed. Ifnecessary some can be thermostaticallycontrolled. Direct fired heaters have a widevariety of applications including factories,warehouses, sports halls, churches, loadingbays and farm buildings.

Indirect FiredIndirect fired heater is a more sophisticatedform of portable heater which is used toprovide large volumes of clean dry heatwithout any products of combustion. Fuel is injected into a gas tight combustion

chamber where it is ignited and burnt at a regulated rate.

The products of combustion are exhausted via a simple flue arrangement to atmosphere.Electric fans provide combustion air and themain air flow which collects heat indirectlyfrom the heated chamber and is then expelledinto the area to be heated.

Indirect heaters are ideal for areas where there islimited ventilation or where there is danger posedby combustible materials. The clean dry heat

produced creates a safe, warm fume free environment. Andrews Sykes indirect heaters are capable,with the addition of an outlet spigot and flexible ducting, of distributing heat to inaccessible locations.They can be controlled by a thermostat or time switch if required. Indirect heaters are best suited toapplications which specifically require their cleaner, dry heat such as the construction industry,showrooms, exhibition halls, marquees, food preparation areas, dry warehousing, garages and clothing manufacture.

ElectricalAndrews Sykes electric heaters are the surest, fastest and handiest way of heating, drying and thawing. All you need is an electrical socket. There are no exhaust gases, smells or vapoursand are therefore ideal for construction projects, marquees, store rooms, workshops, ships,switching stations, garages and in temporary accommodation.

Andrews Sykes Portable HeatersAndrews Sykes Portable Air Heaters will give you instant, efficient flexible heat wherever you wantit and whenever you need it. For over 25 years Andrews Sykes has been the name people haverelied upon for portable heaters in homes, offices, schools, colleges, hospitals, warehouses,garages and factories, in industry, commerce, agriculture or horticulture.

Andrews Sykes heaters are designed and manufactured by the recognised specialists in thefield. They are built to European Standards and are manufactured under the disciplines of aquality Management System which has been assessed and fully approved to the requirement of ISO 9001 and EN 29001.

CalculationsCalculations to determine the correct size of Andrews Sykes portable heaters to use are shown below.

1) Determine the temperature rise required inside the space to be heated in °C.

2) Find the volume of the space in cubic metres i.e. L x W x H in metres.

3) What sort of insulation does the building have?Well insulated k = 1.2Average k = 2.2Badly insulated k = 3.0Hardly any insulation k = 4.0

Amount of heat required = Temperature rise °C x Volume in m3 x K x 4 = Btu/h

NB: divide Btu by 3412 to obtain kW for electric heaters.

For fixed permanent installations a full heat loss calculation must be made to take into accountconstruction of the building, air changes etc. Your local Andrews Sykes depot will be pleased tohelp when required.

Direct Fired Gas Heaters (LPG)

Direct Fired Gas Heaters (LPG) These models are suitable for use with 110 volt or 240 volt electrical supply and are fitted with a gas injector burner. Propane from a suitable cylinder is controlled by the pressure regulatorand supplies the heater through a high pressure gas hose. When the gas relay valve knob isdepressed, gas flows to the burner head where it is ignited by the high intensity electric sparkfrom the piezo ignitor. The safety thermocouple is heated by the flame and feeds a voltage backthrough the thermocouple lead to the gas relay valve, when this voltage is sufficient, the knobcan be released and the burner will run.

The gas relay valve will close the gas supply in the event of flame failure or if an overheatcondition occurs, this will automatically shut off the flame. A safety solenoid is alsoincorporated which gives an instantaneous shut off in the event of a mains electricity failure orthe fan being switched off before the burner is shut down.

An axial fan provides main air flow which combines with burning gas and air mixture to producea large volume of heated air.

The size and quantity of gas cylinders depend on model type and application. Your AndrewsSykes depots will be pleased to advise accordingly.

Heater running times will be extended by increasing the numbers of cylinders used byconnecting them together using pigtail and tee assemblies.

To avoid 'icing' of cylinders in extreme cold weather conditions it will be necessary to increasecylinder quantities to maintain vapour capacity and heater efficiency.

Warning: All direct fired heaters require permanent ventilation to the outsideatmosphere must be provided. Allow 6.5 cm3 for every 293W of heat input.Propane cylinders must be used and stored in accordance with the highlyflammable liquids and liquified petroleum gases regulations 1972.

Direct Fired Oil Heaters

Air Aspirated ModelsAir is drawn into a compressor at the rear of the heater and delivered under pressure to thenozzle, at the same time generating a siphonic action, which induces fuel from the fuel tankthrough a filter. The fuel and air are mixed at the nozzle. The pressurised fuel air mixture is thendischarged into the combustion chamber where a high voltage spark ignites the oil spray.

All models have a flame failure device, which monitors the flame. If the burner fails to light orstops during normal operation the heater will automatically stop and the lockout indicator onthe control panel will illuminate. They also have a safety overheat thermostat; this will shut offthe motor if the normal working temperature is exceeded. These heaters are designed to befuelled by either 28 sec Kerosene or 35 sec gas oil, with some minor adjustment to the burner.They are available for use with either 230 volt or 110 volt electrical supply, and may be operatedvia external thermostats.

Pressure Jet ModelsWith the aid of an electric motor fuel oil is drawn through a pipe from the fuel tank into the fuel pump through a fuel filter. Pressurised oil then passes through the solenoid valve to thepressure jet burner head; surplus oil and any air in the system returns to the fuel tank, via thefuel return pipe. Ignition of the fuel spray is by high voltage spark controlled by a fully automatic safety system complying with BS 799 Part 3 utilising a photo electric cell to monitor

flame failure.

A separate plug is available for the connection of external thermostats or time clocks forautomatic operation. The fan supplies both the combustion air and main air flow and provides a large volume of heated air combined with the products of combustion. When the burner isstopped, either manually or automatically, a thermostat allows the fan to run until the heater iscool, then the fan will stop automatically. A safety overheat limit thermostat will shut off the fuelsolenoid valve if normal maximum working temperatures are exceeded.

These heaters are designed to be fuelled by either 28sec Kerosene or 35sec gas oil, with someminor adjustment to the fuel delivery pressure.

Some of the models listed are available for either 110volt or 230 volt 1 phase. Some are alsoequipped with a cold blow facility for summer ventilation.

Warning: Permanent ventilation to the outside atmosphere must be provided. Allow 6.5 cm2

for every 293W of heat input.

Indirect Fired Gas Heaters (LPG)

Propane vapour is delivered from the cylinders via a pressure regulator to the burner jet, wherewithin the combustion chamber it is mixed with the air being supplied by the burner fan motor,and ignited by a high voltage spark. The gas delivery and spark are controlled by a fullyautomatic safety system, utilising a flame monitoring system.

A separate plug and socket enables the connection of external thermostat, or time clocks forautomatic operation. The gas burner either manually or automatically controlled, warms up theheat exchanger, where the products of combustion are kept separate and are exhausted via aflue. After a short pre-heat period the fan limit thermostat will start the main fan. When the burnerstops the main fan continues to run until the heat exchanger is cool. The limit thermostat willstop the burner if the maximum working temperature is exceeded. These models are available foruse with wither 110 volt or 230 volt 1 phase electrical supply. They are also equipped with a coldblow facility for summer ventilation.

Site Heaters

The FH range of high capacity, heavy duty indirect oil fired heaters, have been specifically developedto overcome applications where a large volume of clean, dry, fume free heat is required.

Similar in operation to the ID heaters, the FH range employs an industrial burner assemblywhich is fuelled by either 28 sec kerosene or converted to 35 sec gas oil, with some minoradjustments (LPG version is also available on request). The burner, which is either manually orautomatically controlled, warms the heat exchanger, after a short preheat period a thermostatwill start the main fan.

The fan used on the FH models is capable of high pressures, which enables the units to be able to operate efficiently even when fitted with long lengths of ducting. The main fan draws in ambient air passes it over the heat exchanger, but is kept completely separate from thedampness and fumes from the combustion chamber. The combustion chamber is vented toatmosphere via a flue stack or flexible flue duct. In certain applications a percentage of thewarm room air can be re-circulated through the FH unit to increase efficiency and reduce fuel costs.

When faced with the problem of providing heat over long distances, up the side of buildings or to large structures the FH range excels, with the capability of being able to provide a highvolume of hot air (up to 500,000 btu), through up to 45 metres of ducting, on each of the supply spigots.

The heavy-duty robust design enables the unit to work unattended and reliably, even under the most arduous conditions. Housed within a completely weather proof steel frame the unitincorporates lifting points, fork lift access and a built in fuel tank. Larger bulk fuel tanks caneasily be piped into the unit with flexible fuel hoses fitted with quick action couplings.

For automatic operation a thermostat, timer or frost stat can be easily fitted. A safetythermostat is standard to protect against flame failure or overheat temperatures. The rangeincorporates all of the usual safety features you would expect to find on an Andrews Sykesheater that is built to stringent European standards.

Applications for the FH range of site heaters■ Construction sites■ Oil refineries■ Distribution centre■ Oil and gas platform construction■ Ship building and large engineering projects■ Large warehouses

■ Marquees and events■ Factories - manufacturing and process■ Specialist flooring and painting■ Building refurbishment and renovation

Electric Heaters

Andrews Sykes can now offer a wide and varied range of electrical heaters for hire, to suitalmost any requirement. From the original DE range which has become a market leader in theUK and Europe for over 20 years, to the latest development in Quartz and Electrical Site heaters- the Andrews Sykes range includes units for 110 volt, 230 volt and 415 volt supplies. Withcapacities from 2.8 Kw up to 40 Kw in single portable units.

DE rangeThree basic models of electric fan heaters are available. The DE25 is a single phase unit, whichis available in a 230v version (ideal for offices, retail or load tests) and 110v (ideal for use onconstruction sites or industrial applications). The unit has a single setting of 2.8Kw output. Aversion of the DE25 is available with a built in thermostat for fully automatic operation. Singlephase units are usually supplied with 2 metres of cable and a plug that is appropriate for thevoltage of the heater. The DE65 is available in 415v 3ph only, this unit has three settings ofeither 6.5kw, 9.5kw or 13kw. Similarly the DE95 is also available in 415v 3ph and has threesettings of either 10 Kw, 15kw or 20kw. The 3ph units would usually be hard wired in by aqualified electrical engineer to the relevant electrical standards, however the units can also beprovided with a short cable tail and a suitable plug, for ease of installation. For automaticoperation both the DE65 and the DE95 can be used in conjunction with the T32 controlthermostat with integral contractor and adjustable settings. The unrivalled reliability anddurability of the DE range has set the standard for electrical heaters in many industrialand commercial applications. All DE units incorporate an overheat protection system for additional safety.

CT rangeThis also consists of three basic models of electric fan heaters. Developed and manufactured in the same factory as the DE range, the CT heaters have been specially designed to operatewith flexible ducting. This enables the units to supply heat to awkward areas where access isdifficult. The small, 20CT, which is only available in 230v 1ph, can be fitted with up to 3 metresof flexible ducting and has a capacity of 2.8Kw. The 40CT is available in 415v 3ph, has anoutput of 10kw (2 settings of 5kw) and can also be fitted with up to 3 metres of flexible ducting.At the top end of the range, the 80CT which is a 415v 3ph heater, with a capacity of 20kw (2 settings of 10kw), can be provided with up to 5 metres of flexible ducting. All of the CT range of heaters feature an integral automatic control stat for additional safety. The double skin outerconstruction ensures that a low surface temperature is maintained, whilst the heater is inoperation. The CT units are built to the same exacting standards we have come to expect from the DE range.

surface temperature and durability. The unit has an electrical protection rating of IP44 and is fittedwith an electrical inlet for ease of installation. An overheat safety system and a 3ph circuit breakerare fitted for added protection, as standard. Industrial type castors and robust lifting handles ensurethe unit remains truly portable. For fully automatic operation, a plug-in external thermostat can beprovided separately.

Radiant QuartzDesigned to achieve local spot heating within large areas, these heaters consist of two short waveinfra-red quartz emitters housed within a strong steel construction cabinet. Each of the emitters, ortubes, produce 1.5kw of heat. The tubes can be used separately or together to produce a total of3kw per heater. The main advantages of a Quartz type heater is that it only heats the areacontained within the bright red glow that is emitted, therefore being ideal for spot heating in largewarehouses or workshops. The bright red glow also generates a feeling of warmth. Anotheradvantage with this type of unit is that the heat is instantly produced with 1 or 2 seconds of the unitbeing switched on, without any warm up period. This makes it ideal for areas that need heating forshort periods of time quickly and efficiently. The units are for use on a 1ph supply only, but can besupplied either in 230v or 110v versions.

Radiant CeramicVery similar in operation to the Quartz heater, these units have three ceramic infra-red elements eachhaving an output of 1kw. The elements can be switched separately or used together to produce atotal of 3kw heating output. The only other real difference between the two models is that theCeramic heaters do not emit the red glow that is produced by the Quartz units.

LotusA smaller lightweight version of the Ceramic heater, mounted within small carrying frame. Usingthe same type of elements as the Ceramic units, the Lotus has 3 settings of 0.8kw, 1.6kw and2.4kw. These units are only available in 230v for operation on a 1ph supply.

Oil filled Radiatorideal for use in sensitive areas where the unit can come into contact with the elderly, infirm oryoung children. This unit has no opening to the heating element, which is insulated within the oilin the radiator. The heat is produced as the element warms the oil, which in turn heats theradiator. Commonly specified in hospitals, nursing homes, schools, public buildings, museumsand art galleries. The unit has two settings, with a total output capacity of 2.5kw and has a builtin thermostat for fully automatic operation.

Small Electric heaters In addition to the units detailed Andrews Sykes also offer a wide range of small electric heaterssuitable for use in domestic, retail or office type environments. The range includes both smallfan heaters and convector heaters. These are generally for use on 230v 1ph electric supplies,having output capacities of up to 3kw. Please contact your local Andrews Sykes depot for moreinformation on these units.

Power = kilowatts (kW)

Current = Amps (A)

Voltage = Volts (V)

Volt drop - The amount of voltage lost when using long cable lengths, causes cable to get hot andbecome unsafe. The motor will also draw excessive current causing overloads to trip and motor tooverheat the maximum permissible voltage drop over a length of cable is 2.5%.

To calculate volt drop use table on page 86 or use the following calculation, based on copper cable.

The above will give the voltage lost in cable length (v) divide by the supply voltage will give the% drop which must not exceed 2.5%

ImportantAlways ensure that the selected cable is suitable for both the current and voltage range of theequipment being used - All electrical installations must comply with the current IEE regulations.
