1 . DELIVERY

Before leaving the factory, each plate heat exchanger from Arsopi, is tested in compliance withthe specifications of the test. Only after total compliance of inspection and testing, can the qualitydepartment give authorisation for despatch. The exchangers are delivered completelyassembled, unless otherwise stated. Depending on the specifications of the contract, theexchanger may be packed or not.Packaging available:

Cardboard box Palette with or without plastic

Box or wooden crate Sea packaging

Wooden platform with or without plastic

If extras such as thermometers or tightening keys are supplied, they are separately packaged butsent along with the exchanger.

The exchanger must be upright and have a sling attached to the head of tightening bolts and The exchanger must never be lifted by the pipe connections (fig.1.3).

To lift the exchanger, it is always necessary to take into consideration its total weight which can befound on the name plate.

You must always use equipment whose capacity is superior to that of the weight ofthe exchanger.

The exchanger should always be moved with care and wherever possible in the uprightposition (the normal position).

2 . INSTALLATION

The exchanger is installed after delivery.The space required for installation at its destination should correspond to (fig. 2.1.)

FIG. 2.1. - REQUIRED SPACE FOR INSTALLATION

In this way, enough clearance around the exchanger facilitates access and permits thenecessary maintenance tasks to be undertaken. The values given in (fig 2.1.) are guide valuesrecommended by ARSOPI-THERMAL. Should there be a problem of limited space, it isrecommended that you consult ARSOPI-THERMAL beforehand in order to find an adequatesolution.

The fixing of the exchanger to the ground, must be done only after the intended site of theexchanger has been levelled. ARSOPI-THERMAL recommends that models of a greater dimension should be fixed in place bymeans of steel bolts, previously inserted before the concrete foundations. Models of a lesserdimension, should be fixed in place with a steel plug after the concrete foundations have been laid.

P R E

- F I X I N G

STEEL BOLTS

Each bolt is positioned in the intended site in accordancewith the dimensions supplied in the design, before the

concrete is laid. The concrete then sets the bolt in placeafter it has dried.

FIG. 2.3. - EXAMPLE OF DETAIL OF FIXING THE FEET TO THE GROUNDWITH INDICATION OF TOLERANCES

After the exchanger has been fixed to the ground, it must be connected to the pipes incompliance with the drawing of location of inlet / outlet.The following points must be taken into account when turning on the exchanger:

Make sure that the dimension A maximum is in accordance with the name plate.

Make sure that none force moment or vibration are acting upon the connections.

Make sure that the pipe system connected to the exchanger is secured againstsudden pressure surges or temperature fluctuations by the use of shut off valves,

safety valves and vent valves.

Make sure, or on the connection plate, that the pipe is applied in such a way as to enable it tobe opened easily. It is advisable, due to the above reason and the fact that thepressure of the plates are variable, to use piping with flexible connections.(see fig. 2.4.).

Please ensure that during the welding of the connection tubing to the heatexchanger no physical contact occurs between the heat exchanger and the tubing,to avoid damage to the heat exchanger plates.

3 . STARTING UP, OPERATION AND SHUTTING DOWN

INITIAL OPERATION

1. Before initial operation make sure that the plate pack is clamped to the correctcompression dimension A maximum;

2. Make sure that all connection pipes are screwed tight;3. Make sure that the permitted values for pressure and temperature given on the name plate

are not exceeded;If these conditions are fulfilled, the exchanger is ready for operation.

STARTING UP THE EXCHANGER - STEPS TO FOLLOW

1. Close the feed valve between the pump and the exchanger;2. Fully open the valve at the outlet connector, if present;3. Open the vent valves;

4. Start the pump;5. Slowly open the feed valve to prevent pressure surges;6. When all the air has escaped from the exchanger, close the vent valves;7. For the second side, repeat steps 1 to 6..

OPERATION OF THE EXCHANGER

When the exchanger is in operation, the operating parameters must not be changed.The maximum operating conditions given must not be exceeded.

STOPPAGES - STEPS TO FOLLOW

1. Slowly close the feed valves, starting with the feed line with the highest pressure;2. Switch off the pumps;3. Close the valves in the outlet pipes, if present.

PROLONGED STOPPAGES ONLY. (SHUTTING DOWN)

4. Switch off all inlet / outlet connections;5. Unload the plate pack to empty the product chambers;6. Flush the plate pack with clean water to remove encrustation and deposits;7. Loosen the plate pack to dimension [ A + 10% ], starting from the current A dimension.

This action reduces the pressure on the gaskets;8. Cover the plate pack with a covering to protect it from dust and light;9. Coat the tightening bolts with a rust-protection agent.

When restarting, proceed as described previously in "operation"




Pág. 6

4 . CLEANING A CLOSED EXCHANGER

The need to clean the exchanger is dictated by the particular application. Always make sure, however, that no encrustation or other deposits form on the plates and thatthese are removed immediately. Encrustation and other deposits impair the heat transferperformance of the exchanger and may cause or accelerate plate corrosion.

-

This is an efficient process of cleaning the exchanger without opening it. Instead of the flowproduct, a cleaning agent is passed through the exchanger. Encrustation and deposits areremoved by the cleaning agent's chemical capacity, supported by mechanical action due toturbulence.

The amount of cleaning solution circulated depends on the design of the exchanger and on theplant where it is installed.

You should use 1,3 times the amount of fluid to that of the normal amount.

STEPS TO FOLLOW IN THE CIP CLEANING PROCESS

1. Immediately after operation and after having flushed out the product with water, continue todo so until the water comes out cleans;

2. Circulate the cleaning solution at pre-determined temperature, for the pre-determined

period of time;

3. Flush with water until it until there is no trace of chemical agent.

The success of this cleaning process can be visually confirmed after finalisation. If necessary, time,concentration and temperature settings should be adjusted.

For the food industry in particular, ARSOPI - THERMAL supplies cleaning and sterilisationinstructions to be used on its exchangers.

Always confirm with the supplier / manufacturer of the chemical agent, itscomposition, to ensure that this does not attack the plates and the gaskets of theexchanger.

At all times must the rules and safety recommendations be applied in referenceto the chemical agent used.

BACK FLUSHING SYSTEM

NORMAL OPERATIONBypass valves open, cleaning valves closed

FILLING (FLUSHING) All valves open

OPERATING IN COUNTER FLOW (BACK FLUSHING)Bypass valves closed, cleaning valves open

Cleaning in reversal of the direction offlow for a short period of time, removesdirt embedded in the plates of theexchanger which can block thechannels.

ENCRUSTATIONS

Each washing cycle is preceded by ashort filling period, where all the fourvalves are open. This is done so as toclean the adjacent piping.

ENCRUSTATIONSREMOVED

This counter flow cleaning system iscarried out, through a conjunction oftubes and valves (see figures) accordingto the flux and type of exchanger inquestion. It's particularly useful, due tolow pressure losses and the fact that noextra piping is needed.




Pág. 8

5 . DISMANTLING AND ASSEMBLING OF PLATE PACK

Every time you open or close the heat exchanger, you must use the correctlubricant in the threaded parts.

DISMANTLING THE PLATE PACK-STEPS TO FOLLOW

The following steps must only be taken after the five steps for stopping the exchanger have beencarried out, which are referred to on page 6, chapter 3.

1. Allow the plate pack to cool down below 40ºC;2. Loosen the tightening bolts alternatively, so that the plates remain parallel and pull them out;3. Unfix the moveable pressu 4. Take out the plates one by one taking care not to deform them. See the fig. 5.1 for the

different types of plates.

Pág. 9

ASSEMBLY OF PLATE PACK - STEPS TO FOLLOW

1. Place the plates against each other in the exchanger, with the gaskets facing towards and sequentially complying to the design of platearrangement. .The plates always remain alternated with type A / type B, or vice-versa.Finally, make sure that the gasket is to be found in its appropriate place.

2. .

3. Tighten the tightening bolts alternately, as referred to in chapter 7 (page 24), so that thepressure plates remain parallel.

4. Check for the desired dimension A and make sure that the same is done in all areas oftightening bolts.




Pág. 10

6 . MANUAL CLEANING OF PLATES

The plates may be cleaned by hand. After removing the plates from the exchanger, they must be cleaned with care, using tepid cleanwater and a nylon brush. A high pressure jet may also be used to clean the plates.Under no circumstances must you exceed the 30 bar of the high pressure jet.When using the brush, take care not loosen the gaskets.

Never use metal objects or abrasives when cleaning plates. Always use soft nylonbrushes (see fig. 6.1).

The high-pressure jet must always be directed face on at the gaskets (see fig. 6.2).

FIG. 6.2.HIGH PRESSURE JET CLEANING

Stubborn contamination such as encrustation can be loosened by soaking in a chemical bath.Choose a cleaning agent suitable for the type of contamination and for the properties of the plateand gasket.

Always obtain confirmation from the cleaning agent manufacturer that the cleaningagents used will not attack the plate or gasket materials.

Normally, in the bath cleaning method, the plates are introduced without the gaskets.If the gasket is fixed, then it must be removed and replace with a new one.

7 . REPLACING GASKETS

As already stated in (chap. 12.2), there are two types of gaskets: fixed with adhesive or slit-in.

GASKETS FIXED WITH ADHESIVE - STEPS TO FOLLOW

1. Remove the old plate gasket by hand. If the gasket still remains intact, gently heat on thereverse side with a low flame.

2. Remove adhesive residues in the groove using a non corrosive solution (e.g.: acetone).

3. Clean any further residue and dry the gasket groove.

4. Apply a thin layer of adhesive uniformly along the periphery of the plate, using a fine brushor manual injection gun.

5. Insert the gasket in the groove and ensure that it is correctly positioned (see fig. 7.1).

6. Stack the plates, making sure that they are done so correctly and apply pressure evenly bymeans of some considerable weight for approx. 12 hours at room temperature.For gaskets EDPM, the minimum recommended time is 24 hours.

in accordance with(chapter 12.4.).The adhesive used is moist with rubber synthetic solids and diluted resin in the solvent referred to as LIOBOND and is supplied by ARSOPI - THERMAL.

This special type of adhesive serves for all types of gaskets and plates.The components of the adhesive LIOBOND obey the requisites of the FDA

for the use of food packaging, in compliance with the code of GovernmentalRegulations of the U.S.A., paragraph 21, section 175.105 - Adhesives and Section 175.300 -Resinous Linings and Polymeric.

10 . GENERAL DESCRIPTION OF EXCHANGER

Plate heat exchangers from ARSOPI are essentially composed of a structural support and apack of heat exchanger plates. The plates are suspended in the upper guide bar and has gaskets on the exterior contour to form narrow chambers and to seal the movement of fluids. Itis via these chambers that a given fluid circulates, which yields or receives the heat of the fluid thatpasses over the opposite surfaces of the same plates. This may be referred to as a plate pack, orplate arrangement.

The frames may be designed in accordance with different codes and standards. Commonexamples of codes are : ASME and AD - Merkblatter.

12 . DESCRIPTION AND DETAILS OF PLATES AND GASKETS

12.1 PLATES

A heat exchanger plate is a thin sheet of metal (normally between 0.5mm and 1 mm), mouldedwhen cold in suitable presses.

Its production complies with a strict control system in which marking the respectivestamping lot assures that each plate can be retraced.

It's grooved geometry allows for an increase in the area of exchange and has the doublefunction of rigidity and giving rise to a great deal of fluid turbulence, when passing through thechannels formed by the contiguous plates.

The plates used in the plate heat exchangers from Arsopi are divided into two types of profile:washboard and herringbone. The former permits a channel between plates with a reduced number of contact points. The latterhas a large number of contact points.

The plates can be prepared either for gaskets fixed with adhesive or without adhesive, which wecall slit-in type.

The material used for the gaskets is determined by temperature conditions, pressure andcompatibility with the fluids.The most common materials used are:

- Stainless steels- Titanium and its alloys- Nickel and its alloys.

Inside each plate model, there may be several types of plates with differing groove geometry. Also, there are plates with hangers or without. (see figures 12.1.3 e 12.1.4)The figure 12.1.5. illustrates these possibilities.

12.2 GASKETS

These are situated on the peripheral groove of the plate and have the double effect of ensuringstoppage and avoiding fluids mixing.

All gaskets are designed to ensure that both fluids at the transfer ports are kept separate fromeach other by means of a double-gasket guidance system. In the event of any leakage in this

area the leakage chamber has the duty of outwardly discharging the liquid via gaps in thesealing webs (leakage grooves) so that any leakage is immediately apparent. (see fig. 12.2.2)

The gasket are wearing parts. Each gasket has its own inner resilience. This resilience isaffected by temperature, pressure and pressing force. Inadmissible temperatures andpressures may reduce this resilience and cause the gaskets to harden.

There are two types of gaskets: Fixed with adhesive and slit-in (without adhesive).The former are fixed to the plate by an adhesive.The latter are held in place by constrictions in the gasket groove.

The gaskets are available in various materials. The choice of the material always takes into

account temperature conditions, pressure, compatibility with the fluids and type of applicationwhether hygienic (FDA gaskets) or industrial.

12.5 RUBBER GASKETS

The feed / discharge connectors situated on the moveable pressu or on theconnecting plate need a gasket ring as shown in figs. 12.5.1. and 12.5.2.This type of ring is fitted without the need of adhesive into the respective groove.They must be replaced after fitting new gaskets.

12.7 CONFIGURATION OF PRODUCT FLOW

The gaskets are fixed on the heat exchanger plates so as to stop and connect, as established, thechannels between the plates.

Each fluid flows through these plates in alternate channels, enabling them to circulate inparallel (if the fluids circulate in the same direction) fig. 12.7.1, or in counter flow (if the fluids

circulate in opposing directions) fig. 12.7.2.

FIG. 12.7.1. FIG. 12.7.2.

Using plates that do not possess four holes, the flow of fluid can be laid out through anexchanger with other configurations - the situation of multi-pass. The fig. 12.7.3. illustrates this point, where the fluids flow through two passes, each possessingthree channels.

FIG. 12.7.3.

Using connection plates enables two fluid flows, whether alike or different, to be treated from onesector to the other.The fig. 12.7.4. illustrates a treatment process with two sectors, separated by an intermediate

element.

13 . TIGHTENING OF PLATE PACK

On the fabrication label attached to the m exchanger, you will find the compression dimensions of the plate pack:

A maximum => Corresponds to the minimum compression of the plates. A minimum => Corresponds to the maximum compression of the plates.

The exchanger is always supplied, when new, with the dimension A maximum, or rather with theminimum compression.Due to the functioning of the exchanger, the gaskets will be subject to wear and this willconsequently result in a reduction of density, which in turn will imply a gradual adjustment ofdimension A .

FIG. 13.1. - FRAME OF EXCHANGER WITH PRESSURE INDICATION

If the exchanger has not been tightened to the dimension A minimum (maximum tightening), youmay continue to do so as long as it's needed. You must not tighten unnecessarily as this maydamage the durability of the gaskets. The exchanger should only be tightened in the case ofgasket leakages or partial change of gaskets (though not advisable).When the dimension A minimum is achieved, or rather, the maximum tightening, the whole set ofgaskets should be replaced.

Ring spanners or manual ratchets are used for the above foresaid purpose. For models of greaterdimension and frequent disassembling of plates, pneumatic tools are recommended.

Do not force the tightening of the plate pack when the gaskets are in new conditionin order not to cause damage on the plates/gaskets.

Never exceed the value of dimension A minimum as this will imply a deformation ofthe heat exchange plates.

The exchanger must be tightened uniformly (see attachment to fig. 13.1.) to ensure

Every time you open or close the heat exchanger, you must use the correctlubricant in the threaded parts.

Measurement betweenthe inner plates of fixed moveable pressure connection plates and

separating plates.

UNIFORM TIGHTENING:You must tightenaccording to the sequenceindicated on the figure, andcontinue doing so until theintended dimension hasbeen reached.
