ASK FOR CUSTOMER SERVICE DESCRIPTION OF THE PLATE HEAT EXCHANGER AND ITS FUNCTION HOW TO READ THE PLATAGE SPECIFICATION INSTALLATION OPERATING INSTRUCTION MAINTENANCE TROUBLE SHOOTING — SPARE PARTS 6 10 12 22 24 Flows in alternate spaces between plates are usually in opposite directions to achieve countercurrent heat exchange. Herringbone patterns on the plates are arranged alternately point-up and point-down. As a result, fluid flow patterns in the spaces between plates are intricate. The resulting turbulent flow enhances heat transfer significantly. Some exchangers have several passes for one or both of the fluids. This is arranged by installing special turning plates at appropriate locations in the plate pack. A turning plate has less than four corners holed. Connections will in this case be required in the movable cover. However, in most cases only one pass is required, and all connections will be located in the stationary cover. There are no flow paths between end plates and covers. The end plates have appropriate port gaskets so that they serve only to make connections with the cover nozzles. Boundary gaskets on end plates serve to distribute cover pressure over the plate. Each plate is supported laterally by points of contact with adjacent plates. The typical unit has plate embossed with a herringbone pattern and arranged Apex-up, then Apex-down alternately. This unit design can withstand high differential pressures without plate deflection, even though those metal barriers are relatively thin. As a result, the plate heat exchanger conserves material. DESCRIPTION OF THE PLATE HEAT EXCHANGER AND ITS FUNCTION Principal parts of the Plate Heat Exchanger: The frame consisting of a stationary cover, and a movable cover, nozzle connections, upper and lower carrying bars, and a pack of thin gauge gasketed plates pressed to a certain corrugated pattern. Tie bolts between the two covers compress the plate pack in place. In compliance with OSHA requirements, a protective panel is supplied to encompass the heat exchanger plate pack as a personnel protective device in the remote event of spraying leakage. The heat transfer surface of the Plate Heat Exchanger is made up of a number of pressed metal plates. On each plate, a boundary gasket confines a flow path inward from one port, across the heat-transfer surface, and out again through a port at the other end of the plate, and two ring gaskets confine the flow path of the second fluid through the remaining two corner portals of the plate, as shown on page 25. On some units, if pressures are very high, the gasket channels may be reinforced mechanically at locations where they are not supported by gaskets in adjacent plates. Because the plates are patterned to create turbulent flow across their surfaces in the spaces between them, and because the flow from space to space is countercurrent, heat transfer is highly efficient. The spaces between plates are small relative to plate area, so that hold-up volume is small with relation to heat-transfer surface area. These factors combine to make the Plate Heat Exchanger more compact than a shell-and-tube heat exchanger designed for the same duty. Geekets are cemented into formed grooves on each plate. Two gasket surfaces are always provided between fluids ina Plate Exchanger. Should a gasket become damaged, leakage is always to the atmosphere. There is no possibility of fluid cross contamination due to gasket failure. Boundary and ring gaskets may be separate pieces (one boundary and two rings required for each plate), or provided as one-piece molded gaskets, with boundary and rings joined by ligaments. Weep holes are provided in ligaments to detect any leakage, within the ring and boundary area. A-PLATES AND B-PLATES As mentioned before, the plates are hanging alternately with apex pointing up and down. A plate with apex pointing down and flow between upper left and lower right corners is called an A-Plate. Correspondingly, a plate with apex pointing up and flow between upper right and lower left corners isa B-Plate. This is demonstrated on page 25. CONNECTING PLATES Sometimes one fluid is cooled or heated, using two different coolants or heat carriers. Normally speaking, this requires two heat exchangers. However, this application can be easily handled in one American Heat frame by simply installing two heat transfer plate packs, properly dimensioned for their separate heat transfer duties, with a connecting plate between them. The connecting plate is a structure with connections, providing inlets and exits for the various fluids. American Heat Division employs computer-rated designs to optimize thermal and pressure drop requirements for each operation. Changing operational requirements can be accommodated by adding, removing, or altering plate arrangements. For heat exchanger performance characteristics, see the specifications sheet (usually a computer print-out). The Plate Heat Exchanrer is designed, tested anc stamped in accordance with the latest ASME Unfired Pressure Vessel Code, Section VIII, Division I or Section III, Class 3 and subsequent accenda. FOR SAFE OPERATION NEVER USE THIS HEAT EXCHANGER OUTSIDE THE LIMITATIONS SPECIFIED ON THE CERTIFIED DRAWING. CONTACT THE MANUFACTURER BEFORE USING THE EQUIPMENT FOR OTHER PURPOSES THAN THAT FOR WHICH IT WAS PROVIDED. HOW TO READ THE PLATAGE SPECIFICATION nner Attached to this Manual is a computer pinted "Platage Specification". The first page is self-explanatory. On the second page, the location of connections is described by symbols. The meaning of these appear from the picture on page 25. For instance: connection location $l would be at the upper, right hand corner of the stationary cover, when looking at it from the outside. Location Tl is upper left hand corner of the movable cover, seen from the outside. The grouping describes the arrangement of flow of the fluids through the heat exchanger. The primary medium appears above the line and the secondary under it. Example 1: 39 —_ means that each fluid is flowing in 39 39 parallel passages in one group only. Example 2: 2 x 3 means that fluid 1 is flowing through 2 - groups with 3 parallel passages in each group, whereas fluid 2 is flowing in 1 group of 7 passages. The following table is useful when the plate pack is to be assembled, the location of plates to be check or replacement plates to be ordered. The table has several columns: The first column (extreme left) is simply the numbering of the plates in consecutive order, starting from the stationary cover. The second column states the identification number of the type of plate at the location. The identification also includes the letter A or B, which makes it easier to check the correctness of plate locations. The following four columns indicate whether or not a hole has been punched in any of the corners, and the corner location is stated at the top of each column. A zero means a hole, a blank means no hole at the corner. Finally, the right hand column shows the flow direction along the gasketed side of each particular plate, up or down. The platage specification ends with a summary of the various plates in the pack, totaled per type/identification number. INSTALLATION Plate Heat Exchangers are assembled and hydrotested at the American Heat Division plant in Branchburg, New Jersey. They are shipped mounted on skids and are ready to be installed. Remove the straps or bolts and the skids and the heat exchanger is ready to be set on a level foundation. When lifting, be sure to use the lugs provided on each cover. CAUTION : DO NOT LIFT UNIT BY NOZZLE CONNECTIONS. Compared to other heat exchangers of comparable heat transfer capacity, the Plate Heat Exchanger is light weight in construction. American Heat Division does not issue any instructions regarding the foundation requirement. See the Certified Drawing for measurements and bolt hole locations. Also see the same drawing for piping connections. The drawing shows the pack length dimension - the distance between inside faces of the covers. The dimension "TD" is a calculated dimension. Deviations of + 1% are acceptable. Torque calculations for the tightening bolts are not required. Check that the covers are exactly that far apart all around their periphery. Tighten or loosen bolts if a correction is needed. Make provisions for thermal expansion when laying out piping. A valve should be provided in each inlet line. Clean foreign matter out of pipe and fittings. Piping must be flexible so that it is not necessary to distort any line in order to mate the flanges. The heat exchanger is then ready for service. NOTE To obtain the longest possible life span of the elastomer gaskets, the plate pack should always be protected against direct radiation of the sun, and kept well away from equipment creating ozone (welding, electric motors in closed rooms with poor ventilation etc.). If stored outdoors, the heat exchanger should be protected by a plastic cover, or similar, against the effects of the weather. OPERATING INSTRUCTIONS CAUTION If the heat exchanger is operated with wide temperature fluctuations, the gaskets will be subjected to strains that may shorten their life. They may leak during the thermal shock periods, even though the leakage normally stops when stable operating temperatures are reached. At startup, the flows of both fluids should be increased gradually. Valves on both fluid line inlets should be provided for this purpose. If the fluids are pumped, start the pumps first against closed valves. Then - with either a pumped system or one with another pressure source - crack both inlet valves slightly. Open them both gradually and slowly until operating pressures and temperatures have been reached. Maximum allowable pressure and temperature are stated on the Certified Drawing. Design flow rates are stated in the Specification Sheet. These should not be exceeded by more than 25%. When shutting down, close both inlet valves slowly and at the same time. If this is not practical, slowly close the valve for the hot medium first. And then shut down the cooling medium. 10 If the heat exchanger is to stand idle for a considerable length of time, drain it and loosen the tie bolts. Then tighten them so that plates and gaskets are in moderate contact. This will keep dust and foreign matter out of the unit. NOTE: Particles larger than 1/16 inch (1/8 inch for P32) in any of the fluids can cause clogging of the internal passages and should not be allowed to enter the heat exchanger. If either fluid is corrosive or if there is danger of freezing, take a shutdown unit apart and clean it. Then reassemble it with plates and tighten the pack to a factor of 1.15 times the tightened dimension listed on the certified print (e.g. 40" TD x 1.15=46"). 11 Valves Set for Operation BACKFLUSHING Valves Set for Backflushing 13 MAINTENANCE One important advantage of the Plate Heat Exchanger, is that it can be taken apart completely for inspection and cleaning. All surfaces in a Plate Heat Exchanger are readily accessible, in contrast to heat exchangers fabricated with welded passages or rolled tubes. The unit must be cooled, drained, the tie bolts removed and the movable cover pulled away from plate bundle. The plates can be taken out individually. American Heat Division Goes not recommend any preventive maintenance or cleaning program for the Plate Heat Exchangers. Unless the owner's experience makes opening of the unit at specific intervals desirable, it is recommended that it not be opened until absolutely necessary. A major increase of the pressure drop at unchanged flow rate without a corresponding reduction of the heat transfer capacity indicates ~ a clogging of the inlet portal. In such cases, a suitable arrangement of valves and pipes on and between the inlet and outlet pipes, to permit a change of the flow directions through the heat exchanger for the fluid in question, is recommended. The intervals between back flushings are based on the user's experience. 12 Verify with the plate pack specification table enclosed with this manual that plate numbers are legible and that plates are in proper order. Mark any plates that have obscure numbers. Looking toward the stationary cover, plates should be numbered at their upper end aad the number sequence should start at the stationary cover. CLEANING THE PLATES CIP (CLEANING IN PLACE) Cleaning by circulation of Chemicals, by back-flushing, by brushing or by any other suitable method should be carried out at intervals based on experience, to ensure that the required Heat Transfer capacity is maintained and that pressure drops do not exceed acceptable values. MANUAL CLEANING Unless there is some problem material to remove, the plates can be cleaned without removing them from the unit. Use a hand brush, a rotary power brush or a high pressure water jet. Brushes with fiber nylon or stainless steel bristles are often used. 15 DISASSEMBLY Cool the unit to room temperature and drain before attempting disassembly. Facilities should be provided for flushing out both sides of the heat exchanger with cold water. Loosen and remove any piping connections on the movable covers. Remove the protecting panels. Loosen nuts on the cover tie bolts at the four corners first. Back the nuts off and remove the bolts. Then loosen nuts in the center portion of each side of the cover about 1/2 inch. Leave them, then loosen the other tie bolts about 1/2 inch. Continue this process until the nuts are slack. Finally, back off the nuts on the center bolts and remove them. The movable cover can now be pulled clear of the plates. Separate the plates from one another carefully. All gaskets should stay in their grooves - should not stick to adjacent plates. If a short length of gasket should come loose, cement it back in place immediately. But if the entire gasket is loose or if it seems to be damaged, remove the plate and do a complete repair job. 14 CAUTION Do not use brushes with carbon steel bristles. Do not use steel wool. Be careful not to damage the gaskets. Hard deposits (Oxides, Limestone) can be removed using a brush and 10% Nitric Acid (1 part 65% acid, specific gravity 1.4, to 9 parts of water). IMPORTANT - The acid can cause serious damage upon contact with your skin or eyes. Always use protecting glasses and rubber gloves when handling it! 16 REPLACING GASKETS Remove plates with loose or damaged gaskets. Scrape out any pieces of gasket material that may remain in the gasket grooves. Clean out all traces of oil, grease or foreign matter from the grooves. Use a nylon or stainless steel wire brush and a solvent such as toluol, xylol, trichlorethylene or ethyl acetate. Wipe the grooves dry. To check whether they are completely grease-free, pour some water in them. If they are grease-free, the water will wet their surfaces, and it will form a thin film instead of gathering in nodules. When the grooves are clean and grease-free, wipe them dry again. Apply a bead of Pliobond 20 in each groove about 1/8 inch in diameter. Use a flexible plastic container with a spout on it. Let the cement dry until tack time, which normally is between 10 and 20 minutes. Apply cement to the gaskets the same way after having buffed the gasket surface with fine sandpaper and dusted it off. Let them dry. NOTE Gaskets are color-coded at about the 3-O'clock positions to identify their compositions. Color codes of different suppliers may not correspond. The color-coded side should be out. Apply cement to the opposite side, and be very careful to keep cement off the color-coded side. 17 ASSEMBLY Consult the Platage Table for correct plate installation. If several plates were removed, put them back in the frame in the proper numerical order. Move the pack of plates away from the fixed cover. Apply the parting agent, DC 200 silicone oil to the back of the first plate. Give it a very thin coat where it will mate with gaskets on the fixed cover. Slide the plate against the cover. Now, do the same thing to the second plate and to each of the plates. Slide each one against its mating plate as you work. Look at the gaskets each time to see where the mating surfaces will be. If all the plates were removed, arranged them in numerical order. The fumbers are stamped on the gasket sides -- the sides that face you as you look at the fixed cover. They are at the upper left hand corners of the plates. Number 1 goes against the fixed cover. Assemble the others against it in numerical sequence. Handle the plates carefully to avoid damaging them or their gaskets. Apply the parting agent, DC 200:;silicone oil to the backs of the plates as described above. CAUTION While applying silicone oil and assembling the plates one-by-one, inspect each plate to be sure that all gaskets are sound and that there is no foreign matter on surfaces that will mate with gaskets already in place. REPLACING GASKETS (CONTINUED) When the cement is ready, fit gaskets into their channels. If any stretching is necessary, do it in the middle of the straight long sides -- not at the corners. Press the gaskets down all around to be sure that they are firmly cemented in place. REPLACING PLATES If a plate is damaged, it can be replaced, but the replacement must be of the same type. It should be marked with the same number as the plate it replaces. Consult American Heat Division to obtain the proper replacement. In an emergency, a standard plate (with four ports) can be removed. Then, an adjacent standard plate must also be removed in order to keep the flow pattern right. Capacity of the unit will be reduced very slightly, but operation will otherwise be normal. The pack length dimension will be reduced, of course, as each pair of plates is removed. Multiply the former pack length = NUMBER OF PLATES NOW Y NUMBER OF PLATES ORIGINALLY to calculate the new pack length. 18 TIGHTENING THE PLATE PACK The important things to watch for when tightening the tie bolts are that the movable cover should not be cocked at an angle and that bolt tensions should be built up evenly. Clean the bolt threads and cover them with a heavy duty lubricant. Push the movable cover into place against the pack of plates. Insert the bolts and run the nuts up until there is some resistance. Measure the pack length between covers all around. Tighten the nuts that will bring the two covers parallel. Now, continue crosswise to tighten all the nuts as described on the following page, keeping the covers parallel. Check the pack length dimensions as you proceed. The length of the tightened pack should not exceed the length dimension on the Certified Drawing by more than + 18%. Finally, check the dimension between covers all around to be sure that they are still parallel. If they are not, make them so. Before putting the unit back into service, hydrostatically test both sides independently if this is feasible, to make sure that the unit will be tight at your working pressure. 20 tT Opening of Plate Heat Exchanger: (1) (2) (3) (4) (5) Bolts #1 and #8 removed Bolts #4 and #5 removed Bolts #2 and #6 relieved 1/2" Bolts #3 and #7 relieved 1/2" Repeat (3) and (4) until bolts are loose and can be removed. Retightening of Plate Pack: (6) (7) (8) (9) (10) Put all bolts back in the slots in the covers and run up all nuts until there is some resistance. Threads should be cleaned and greased. Tighten bolts #2 and #6 about 1/2’ Tighten bolts #3 and #7 about 1/2" Repeat (7) and (8) until correct measurement between covers is obtained (see Cert. Drwg.) When necessary, follow up with bolts #1, 4, 5 and 8 to maintain flat- ness of covers. Note that bolt torque values are not needed for correct compression of the plate pack and therefore are not stated by American Heat. When completed, all 8 bolts should be installed and tightened as per (9) above. SUBONVHOXG LVSH SLW1d 40 SNINGLHOTISY CNV ONINSdO CORROSION When the materials to be used in a Plate Heat Exchanger are determined, the choice is based on the combined experience and knowledge of the owner-to-be and American Heat Division. Still, lack of adequate information, or changing conditions may lead to corrosion attacks of some kind to the plates. Should this happen, it may be of value to know the nature of the attacks, and the following short guide may be of some assistance to you. 1. General Corrosion More or less evenly distributed on the surface through contact with acids. The progress of the attack is dependent on acid concentration, temperature and sometimes velocity of liquid. 2. Point Attacks (Pitting) Deep, local pits caused by the presence of chlor - or brom- ions, when the steel is in contact with a watery solution of metal chlorides or bromides. Degree of attack influenced by acidity, temperature and redox- potential. 3. Crevice Corrosion Local attacks in areas of stagnant fluid, for instance in narrow crevices. 4. Stress Corrosion Combined effect of stress in material and chemical environ- ment, for instance chlorides on stainless steel or ammonia on brass. a aeEEEneERIRER al 23 TROUBLE-SHOOTING SYMPTON PROBABLE CAUSE CORRECTIVE ACTION High pressure drop Fouling with Chemically clean in either stream, material affected passages reduced heat deposited by by circulation transfer at fluid or Disassemble the unit and clean the plates. a High pressure drop Clogging of Back flush the but still good inlets unit. heat transfer at Front flush the rated capacity unit. ee ——— Leakage 1.

Usually, the only parts subject to sudden damage would be the plates or gaskets. If this happens to a limited number of regular, four- holed plates. the situation can be handled as described under MAINTENANCE, Replacing Plates. The removed plates can be either repaired or spare parts ordered according to the table in the Platage Specification. However, there may be cases of severe conditions, which justifies a certain stock of selected spare parts. In such cases, a list of recommended parts can be made up at any time by American Heat Division. If gaskets or plates with gaskets are to be stored, they should be kept at normal room temperature and humidity in a preferably dark room, at least out of the direct radiation of the sun or any other heat source, and well away from equipment causing ozone in the air (arc weld, electrical motors). If loose gaskets are stored for a longer time in a twisted shape, they may be difficult to straighten out, and they may cause problems when they are needed for gasketing. 24 STATIONARY MOVABLE NOZZLE LOCATIONS IN MOVABLE COVER TI, T2,T3,T4 POSSIBLE 192,83, IN STATIONARY COVER: SI $4 NOZZLE LOCATIONS POSSIBLE T3 25 ®& ALFA-LAVAL THERMAL Co.
