EVAPCO, long known for using premium materials ofconstruction, has developed the ultimate system for cor-rosion protection in galvanized steel construction – theEVAPCOAT Corrosion Protection System. Marrying cor-rosion free materials with heavy gauge mill hot-dip gal-vanized steel construction to provide the longest lifeproduct with the best value.

The Evapcoat Corrosion Protection System consist of:

• Z-725 Mill Hot-Dip Galvanized Steel Construction

Mill hot-dip galvanized steel has been successfully usedfor over 25 years for the protection of evaporative con-densers against corrosion. There are various grades ofmill galvanized steel each with differing amounts ofzinc protection. EVAPCO has been a leader in theindustry in developing heavier galvanizing, and was thefirst to standardize on Z-600 mill hot-dip galvanizedsteel. Now, EVAPCO is, once again, increasing the levelof corrosion protection by being the first and only man-ufacturer in Europe to use Z-725 mill hot-dip galvanizedsteel.

Z-725 designation means there is a minimum of 725 gof zinc per m2 of surface area present on the steel.Z-725 is the heaviest level of galvanizing available formanufacturing evaporative condensers and has over 2.5times more zinc protection than competitive designsusing Z-275 steel. With Z-725 mill hot-dip galvanizedsteel construction, EVAPCO provides galvanized steelpanels with corrosion protection that approaches thelevel of the hot-dip galvanized heat exchanger coils.

During fabrication, all panel edges are coated with a95% pure zinc-rich compound for extended corrosionresistance.

• Type 304 Stainless Steel Strainers

Subjected to excessive wear and corrosion, the sump strai-ner is critical to the successful operation of the condenser.EVAPCO uses only stainless steel for this very importantcomponent.

• PVC Air Inlet Louvers

The innovative design uses corrosion free materialswhile effectively eliminating splash out and reducingthe potential for algae formation inside the condenser.

• PVC Drift Eliminators

The final elements in the upper part of the condenserare moisture eliminators which strip the entrainedwater droplets from the leaving air stream.

EVAPCO eliminators are constructed entirely of inert,corrosion-free PVC. This PVC material has been speciallytreated to resist damaging ultraviolet light. The elimina-tors are assembled in easily handled sections to facilitateremoval thereby exposing the upper portion of the unitand water distribution system for periodic inspection.

• PVC Water Distribution System, ZM II™ Spray Nozzle

The fixed position ZM II™ Spray Nozzles are mounted incorrosion-free PVC water distribution pipes. Together,these elements combine to provide unequaled coil cov-erage, scale prevention and make the industries bestperforming non-corrosive, maintenance-free water dis-tribution system.

• Totally Enclosed Motors

EVAPCO uses totally enclosed motors for all fan andpump motors as standard. These superior motors helpto assure longer equipment life without motor failures,which result in costly downtime.

• Alternate Materials of Construction

EVAPCO induced draft condensers have a modular designwhich allows for specific areas to be enhanced forincreased corrosion protection. For particularly corrosiveenvironments, EVAPCO condensers are available withStainless Steel construction for the basin, casing and/or coil.

• Stainless Steel Basin - welded execution

The basin area of a condenser is often subjected to highconcentrations of impurities and silt. In addition to theEVAPCOAT Corrosion Protection System, EVAPCO offersoptional welded stainless steel construction for superiorcorrosion resistance. This option provides Type 304 orType 316 stainless steel for the entire basin section -including the support columns and air inlet louverframes.

• Stainless Steel Coils

The heat exchanger coil is the heart of the evaporativecondenser. For this critical component, EVAPCO offersthe options of Type 304 or type 316 stainless steelconstruction.

Water ManagementHigh Efficient Water Saver Drift EliminatorsAn extremely efficient drift eliminator system is stan-dard on EVAPCO condensers. The patented systemremoves entrained water droplets from the air streamto limit the drift rate to less than 0.001% of the recircu-lating water rate. With a low drift rate, EVAPCO con-densers save valuable water and water treatmentchemicals. The drift eliminators are constructed of aninert polyvinyl chloride (PVC) plastic material whicheffectively eliminates corrosion of these vital compo-nents. They are assembled in sections to facilitate easyremoval for inspection of the water distribution system.

Superior WST Air Inlet Louverand Screen DesignEVAPCO’s patented WST Inlet Louvers keep water inand sunlight out of the basins of induced draftproducts. The unique non-planar design is made fromlight-weight PVC sections which easily fit together andhave no loose hardware, enabling easy basin access.

Developed with computational fluid dynamics (CFD)software, the louver’s air channels are optimized tomaintain fluid dynamic and thermodynamic efficiencyand block all line-of-sight paths into the basin elimi-nating splash-out; even when the fans are off.Additionally, algae growth is minimized by blocking allsunlight.

The combination of easy basin access, no splash-out andminimized algae growth saves the end user money onmaintenance hours, water consumption and watertreatment costs.

“Clean Pan” Basin DesignEVAPCO condensers features a completely sloped basinfrom the upper to lower pan section. This “Clean Pan”design allows the water to be completely drained fromthe basin. The water will drain from the upper sectionto the depressed lower basin section where the dirt anddebris can be easily flushed out through the drain. Thisdesign helps prevent buildup of sedimentary deposits,biological films and minimizes standing water.

ZM II™ Spray NozzleWater DistributionSystemEven and constant water distri-bution is paramount for reli-able, scale-free evaporativecooling. EVAPCO’s ZeroMaintenance ZM II™ SprayNozze, mounted in a PVC distri-bution pipe remains clog-freeunder the toughest conditionsto deliver approximately 4 l/s toevery square meter of coil planarea.

The heavy-duty nylon ZM II™Spray nozzles have a 33 mmdiameter opening and a 38 mmsplash plate clearance, enablingEVAPCO to use 75% fewernozzles.

Two Speed MotorsTwo speed fan motors can provide an excellentmeans of capacity control. In periods of lightenedloads or reduced wet bulb temperatures, the fanscan operate at low speed, which will provide about60% of full speed capacity, yet consume only about15% of the power compared with high speed. Inaddition to the energy savings, the sound levels ofthe units will be greatly reduced at low speed.

Inverter Duty MotorsInverter Duty motors are available for condenserapplications which utilize variable frequency drivesystems for capacity control. Inverter Duty motorsoffer totally enclosed premium efficiency construc-tion which is designed for variable frequency driveapplications.

Note: Other special motor configurations are avail-able to meet specific proper requirements. Contactyour local EVAPCO sales representative for applica-tion assistance and motor availability.

Remote Sump ConfigurationFor units operating in areas where temperaturesmay be very low,or where lowtemperatures mayoccur duringperiods when theunit is not opera-ting, a sump loca-ted inside thebuilding is thepreferred meansof ensuring thatthe basin waterwill not freeze.For these applica-tions, the conden-ser will be supplied without the spray pump,suction strainers and all associated piping, but withan oversize bottom outlet.

Dual Fan OptionEvapco now offers a Dual Fan arrangement on10x18, 12x18 and 12x20 nominal box sizes.

The Dual Fanoption gives usersredundancy inlarge box sizes byproviding indepen-dant motors, fans,and drives thatpreviously onlyhad a single fanand motor.

Basin Heater PackageIf a remote sump configurationis not practical, electric basinheater packages are availableto help prevent freeze-up ofthe basin water. The packagesinclude electric heater ele-ments and a combination withthermostat and low water cut-off. (Consult EVAPCO forheater size and application)

Electric Water Level ControlEvaporative condensersmay be ordered with anelectric water level controlin lieu of the standardmechanical float andmake-up assembly.This package providesaccurate control of waterlevels and does notrequire field adjustment.

Multiple Circuit CoilsCondensers may be supplied with multiple circuit coils tomatch various system requirements such as split systems.

Self Supporting Service PlatformsCondensers are available with self-supporting serviceplatforms that include access ladders which are designed foreasy field installation. This option offers significant savingsin comparison to field constructed, externally supportedcatwalks. The EVAPCO service platform option will beinstalled in front of the fan access doors.

Motor DavitIn the event that a fan and/or fan motor should need to bereplaced, a motor davit is available from which a chain fallcan be mounted to easily lower the motor/fan to theground.

DesignEvapco units are of heavy-duty construction and designed forlong trouble-free operation. Proper equipment selection,installation and maintenance is, however, necessary toensure full unit performance. Some of the major considera-tions in the application of a cooler are presented below. Foradditional information, please contact the factory.

Air CirculationIt is important that proper air circulation be provided. Thebest location is on an unobstructed roof top or on groundlevel away from walls and other barriers. Those condenserslocated in wells, enclosures or adjacent to high walls mustbe properly located to avoid the problems associated withrecirculation.Recirculation raises the wet bulb temperature of the ente-ring air causing the water temperature to rise above thedesign. For these cases, the discharge of the fan should belocated at a height even with the adjacent wall, therebyreducing the chance of recirculation. For additional infor-mation, see the Evapco Equipment Layout Manual.Good engineering practice dictates that the condenserdischarge air not be directed or located close to or in thevicinity of building air intakes.

Recirculating Water SystemThe surest way to protect the recirculating water systemfrom freezing is with a remote sump. The remote sumpshould be located inside the building and below the unit.When a remote sump arrangement is selected, the spraypump is provided by others and installed at the remotesump. All water in the condenser basin should drain to theremote sump when the spray pump cycles off.Other freeze protection methods are available when aremote sump is not feasible. Electric pan heaters can be usedto keep the pan water from freezing when the unit cyclesoff. Water lines to and from the unit, spray pump and relat-ed piping should be heat traced and insulated up to theoverflow level in order to protect from freezing.The unit should not be operated dry (fans on, pump off)unless the basin is completely drained and the unit has beendesigned for dry operation. Consult the factory when dryoperation is a requirement.

Maintaining the Recirculated WaterSystemThe heat rejection in a condenser is accomplished by theevaporation of a portion of the recirculated spray water. Asthis water evaporates, it leaves behind all of its mineral con-tent and impurities. Therefore, it is important to bleed-off anamount of water equal to that which is evaporated to pre-vent the build-up of these impurities. If this is not done, themineral or the acidic nature of the water will continue toincrease. This will ultimately result in heavy scaling or a cor-rosive condition.

Bleed-offEach unit supplied with a pump mounted on the side is fur-nished with a clear bleed line for visual inspection and a valvewhich, when fully open, will bleed-off the proper amount ofwater. If the make-up water supplying to the unit is relativelyfree of impurities, it may be possible to cut back the bleed,but the unit must be checked frequently to make sure scale isnot forming. Make-up water pressure should be maintainedbetween 140 and 340 kPa.

Water TreatmentIn some cases the make-up water will be so high in mineralcontent that a normal bleed-off will not prevent scaling. Inthis case, water treatment will be required and a reputablewater treatment company familiar with the local water con-ditions should be consulted.Units constructed of galvanized steel operating withcirculating water having a pH of 8,3 or higher will requireperiodic passivation of the galvanized steel to prevent theformation of “white rust”.Any chemical water treatment used must be compatible withthe galvanized construction of the unit. If acid is used fortreatment, it should be accurately metered and the concen-tration properly controlled. The pH of the water should bemaintained between 7 and 8,8. Batch chemical feeding is notrecommended because it does not afford the proper degreeof control. If acid cleaning is required, extreme caution mustbe exercised and only inhibited acids recommended for usewith galvanized construction should be used.

Control of Biological ContaminationWater quality should be checked regularly for biological con-tamination. If biological contamination is detected, a moreaggressive water treatment and mechanical cleaning pro-gram is required. The water treatment program should beperformed in accordance with local legislation and in con-junction with a qualified water treatment company.It is important that all internal surfaces be kept clean ofaccumulated dirt or sludge. In addition, the drift eliminatorsshould be kept in good operating condition to minimizewater from exiting the condenser unit in the discharge air.To minimize the risk of biological contamination, at initialstart up or after an extended shut down, it is recommendedthat the condenser be properly treated. Clean all debris suchas leaves and dirt from the unit. Completely fill the basin tothe overflow level with fresh water. Initiate a biocide watertreatment or shock treatment program prior to operatingthe unit. It is preferable that all such procedures be conduct-ed or supervised by a water treatment specialist.

PipingEvaporative condensers are used in refrigeration systemsas an efficient means of heat rejection. Their installationand specifically the installation of the piping to and fromthe evaporative condenser has a direct effect on theiroperation and the overall energy efficiency of the refrig-eration system. In this manual, we will explore the princi-ples of piping evaporative condensers, beginning withsingle condensers and exploring multiple condenserinstallations as well as thermosiphon and sub-cooling pip-ing systems.

BackgroundEvaporative condensers came into common use for nearly allrefrigeration systems because of their operating advantagesover the combination of cooling towers and condensers.They, of course, have also replaced the old "once through"water cooled condensing systems which are obsolete todaybecause of the restrictions on the unlimited use of watercoupled with its high cost.Although, shell and tube condensing systems performed thesame job of condensing the hot discharge gas into a saturat-ed liquid as evaporative condensers; a small difference in theoperating characteristics, namely pressure drop, requiressome modification in the refrigerant piping hookup to andfrom the evaporative condenser. These changes are particu-larly important when dealing with multiple unit installations.In order to understand why the piping hookup is important,let's first take a brief look at the basic design differences ofthe two types of condensers to see why there is a differencein the pressure drop characteristics.

The shell type refrigerant condensers allow the refrigerant toflow around and condense on the outside of the watertubes. (See Figure 1) The refrigerant flow is almost entirelyunimpeded resulting in a very low or nearly zero pressuredrop through the condenser.

APPLICATIONS


Contrasting, most evaporative condensers (See Figure 2) uti-lize some type of serpentine coil design where the hot refrig-erant gas enters the top of the coil traveling back and forththrough several rows as it is cooled and changed from a hotsuperheated gas to a saturated liquid. This longer travel pathgenerally produces a small pressure drop which, thoughinsignificant to the overall operation of the refrigeration sys-tem, does require proper attention be given to the con-denser piping. Most of this attention needs to be focused onthe liquid drain line from the outlet of the evaporative con-denser to the high pressure receiver. The reason for this isdescribed in the “Piping Brochure”.

SOUND BAS IC

SoundSound is the alteration in pressure, stress, particle displace-ment and particle velocity, which is propagated in an elasticmaterial. Audible sound is the sensation produced at the earby very small pressure fluctuations in the air.

Sound PressureSound pressure is the intensity of sound. Sound pressure, Lp

in decibels is the ratio of measured pressure, P in the air to areference sound pressure, PO = 2x10–5 Pascal following thefollowing formula:

Lp (dB) = 10 log10 ( P2/ PO2)

The most important point to understand about sound pressure level is that sound pressure level is what is actually being measured when sound data is recorded.Microphones that measure sound are pressure sensitivedevices that are calibrated to convert the sound pressurewaves into decibels.

Sound PowerSound Power is the energy of sound. Sound power, Lw indecibels is the ratio of the calculated sound power, W to a reference power, Wo =1 picowatt, according to the following formula:

Lw (dB) = 10 log10 (W/Wo)

The most important point to remember about sound power level is that sound power level is not a measuredvalue, but is calculated based on the measured sound pres-sure.

Adding Multiple Sound SourcesSince the decibel is a logarithmic function, the numbers arenot added linearly. Therefore, two 73 dB sound sourcesadded together do not equal 146 dB. The resultant soundwould actually be 76 dB. The following table shows how toadd decibels from two sound sources.

Sound Frequency

Fan Noise• Low / Mid frequencies that travel long distances,

through walls, and around obstructions.

• Very difficult to attenuate. Reduce fan noise byusing Low Sound Fans.

• Dominates what is measured and heard at theCondenser and at the sound sensitive location.

Water Noise• High frequencies that attenuate naturally with

distance. Attenuated easily by walls, trees or other obstructions.

• Totally masked and drowned out by fan noise at ashort distance away from the Condenser.

Notable Facts about Sound:

• +/- 1 dB(A) is inaudible to the human ear • Decreasing a noise source by 10 dB(A) sounds

half as loud to the human ear

Sound Pressure – The A-Weighted ScaleThe A-weighted scale, dB(A) is a means to translate what a sound meter microphone

measures to how the human ear perceives the sound.

SPEC I FY ING SOUND

SoundVerifications

Specify sound pressure in dB(A) measured 1,5 m above the fan discharge during full speed operation.• All manufacturers can meet a performance specification with Low Sound Options• Fan noise is what matters. 1,5 m above the fan is where it matters.

Measurement LocationPer Cooling Technology Institute Standard ATC-128

Sound Microphone location 1,5 m above the evaporative condenserfan cowl edge at a 45° angle.

This position assures accurate sound measurements by eliminatinga source of uncertainty by taking the microphone out of thehigh velocity fan discharge air.

Easy VerificationAt 1,5 m from the Evaporative Condenser, a sound meter records only condenser noise. Interested parties can easilyverify the actual noise coming from the condenser against the specified sound data with good certainty.

If sound were specified at 15 meters or some greater distance fromthe sound sensitive location, there is increased uncertainty in themeasured data due to other possible sound sources within the 15meters radius of the sound microphone.

Sound QualitySound coming from the top of the condenser is comprised of low-and mid-frequency fan noise. Low- and mid-frequency fan “rumble”is very difficult to attenuate. Fan rumble travels through everythingand around everything and what is audible at any sound sensitivelocation.

Sound coming from the sides of the condenser is comprised of highfrequency water noise, is much less objectionable than fan noise andattenuates naturally with distance.

Acoustical Shadow*“Subjective reactions to the overall noise generated byCondensers indicate that as one walks away from a towerintake, a point is reached where the water noise is masked bythe fan noise. The point coincides with the point at which oneemerges from the acoustical shadow of the condenser structure,which shields intake water noise from discharge fan noise.” *Seelbach & Oran, “What To Do About Cooling Tower Noise”, Industrial Acoustics Company.

Sound measured at the side of an Evaporative Condenser isinside the acoustical shadow of the noise emitted from the top.Outside the acoustical shadow, the low- and mid-frequency fannoise completely masks the high frequency water noise.

IBC


EVAPCO Evaporative Condensers…designed to withstand seismic

or wind load forces.

The International Building Code (IBC)

is a comprehensive set of regulations

addressing the structural design and

installation requirements for building

systems – including HVAC and

industrial refrigeration equipment.

With the advent of the IBC,

EVAPCO is proud to introduce the

new and improved line of ATC-E

Evaporative Condensers with IBC 2012

compliance standard.

What is IBC?

International Building CodeThe International Building Code (IBC) is a comprehensiveset of regulations addressing both the structural design andthe installation requirements for building systems – includ-ing HVAC and industrial refrigeration equipment. Compared to previous building codes that considered onlythe building structure and component anchorage, therequirements contained within the IBC address anchorage,structural integrity, and the operational capability of acomponent following either a seismic or wind load event.Simply stated, the IBC code provisions require that evapo-rative cooling equipment, and all other components per-manently installed on a structure, must be designed tomeet the same seismic or wind load forces as the buildingto which they are attached.

How Does IBC 2012 Apply to EvaporativeCondensers?Based on site design factors, calculations are made todetermine the equivalent seismic “g force” and wind load(kilo-Newton per square meter, kN/m2) on the unit. Theevaporative condenser must be designed to withstand thegreater of either the seismic or wind load.

All locations with design criteria resulting in a seismicdesign force of up to 1.0g or a wind load of 6,94 kN/m2 orbelow will be provided with the standard ATC-E structuraldesign. An upgraded structural design is available forinstallations with design criteria resulting in “g forces”greater than 1.0g. The highest “g force” location in NorthAmerica is 5.12g. The highest wind load shown on themaps is 273 km/h, which is approximately equal to 6,94kN/m2 velocity pressure. Therefore, the upgraded structuraldesign package option for the New ATC-E is designed for5.12 g and 6,94 kN/m2 making it applicable to ALL buildinglocations in North America.

Design ImplementationEVAPCO applies the seismic design and wind load informa-tion provided for the project to determine the equipmentdesign necessary to meet IBC requirements. This processensures that the mechanical equipment and its componentsare compliant per the provisions of the IBC as given in theplans and specifications for the project.

Independent CertificationAlthough the IBC references and is based on the structuralbuilding code ASCE 7, many chapters and paragraphs ofASCE 7 are superceded by the IBC, independent certifica-tion and methods of analysis are such paragraphs. Per themost recent edition of the code, the EVAPCO complianceprocess included an exhaustive analysis by an independentapproval agency. As required by the International BuildingCode, EVAPCO supplies a certificate of compliance as partof its submittal documents. The certificate of compliancedemonstrates that the equipment has been independentlytested and analyzed in accordance with the IBC seismic andwind load requirements. Evapco has worked closely withthe independent approval agency, The VMC Group, to com-plete the independent equipment testing and analysis.

If the seismic “g force” or wind load psf requirements forthe project site are known, EVAPCO’s online equipmentselection software, EvapSelect™, will allow you to choose therequired structural design package – either standard con-struction or upgraded construction.

For further questions regarding IBC compliance, please con-tact your local EVAPCO Representative.

In its continuing commitment to be the leaders in evaporative cooling equipmentdesign and services, EVAPCO ATC-E Evaporative Condensers are now Independently

Certified to withstand Seismic and Wind Loads in accordance with IBC 2012.

The recommended support for EVAPCO condensers isstructural “I” beams located under the outer flangesand running the entire length of the unit.Mounting holes, 19 mm in diameter are located inthe bottom channels of the pan section to provide forbolting to the structural steel. (Refer to certifieddrawings from the factory for bolt hole locations.)

Beams should be level to within 3 mm per 2 m beforesetting the unit in place. Do not level the unit byshimming between it and the “I” beams as this willnot provide proper longitudinal support.
