CONSTRUCTION 5.1. Standard Design The APV GPHE is designed to provide maximum efficiency and cost effectiveness in handling heat transfer duties. The GPHE minimizes maintenance downtime and requires little floor space compared with other types of heat transfer equipment. The heat transfer plate is a thin, corrugated metal sheet that transfers heat between the fluids on either side.
Page 16
Sanitary GPHE’s are equipped with adjustable ball feet, which provide a point contact, for levelling the plate heat exchanger to ensure the GPHE can fully drain. A sanitary GPHE that can be fully drained meets one of the requirements for stamping a GPHE with the 3-A logo.
Page 18
Figure 4: Industrial GPHE frame Figure 5: Sanitary GPHE frame Divider plates may be used to divide a heat exchanger into separate operating sections. Divider plates have no connections but may allow flow from one section to the next. Connector grids (Figure 6) may be used to divide a heat exchanger into separate sections to accommodate multiple duties within a single frame.
Page 19
Figure 6: Connector Grid 5.3. Plates APV heat exchanger plates come in multiple sizes and corrugation patterns. This allows the heat exchanger to be matched closely to a specific duty. The corrugations cause turbulence in the liquids as they flow in a thin stream in the passage between each plate (Figure 7).
Page 21
Plate Construction All plates are designated as either diagonal flow or vertical flow (Figure 9) based on their flow pattern. Vertical flow plates have both flow inlet and outlet ports on the same side, e.g., left side for the hot medium and right side for the cold medium. For diagonal flow plates, the fluid enters in one corner and exits in the diametrically opposite corner.
Page 22
This is available for many APV GPHE models. Mixing plate angles results in flow passages that differ significantly in their flow characteristics.
Page 23
Leakage from an APV DuoSafety plate is always the early warning for the user to act. Note: APV DuoSafety plates use special gaskets which can be confused with gaskets intended for single plates. Please confirm with SPX FLOW that you have the correct gaskets. Welded Plate Pairs An APV welded plate pair is a right- and left-hand vertical flow plate laser welded together to form a pair.
Page 24
the welded passage cannot be prevented, then a cleaning solution must be circulated. It is recommended that you contact a supplier of cleaning agents for advice. The welded and gasketed chambers of an APV welded plate pair may have different pressure and fluid capabilities. Ensure the fluids are connected correctly.
Page 25
The upstanding lugs (Figure 14) maintain plate alignment in the plate during plate pack closure and operation. The groove form provides 100% peripheral support of the gasket, leaving none of the material exposed to the outside. In addition, the gasket exposure to the process liquid is minimized by the full depth plate gasket groove.
Page 26
5.5. Connector Grid and Bosses The connector grid divides the plate heat exchanger into separate sections that may operate independently. The connector grid is equipped with removable connector bosses (Figure 15). The connector bosses can also form the connections between sections of the plate heat exchanger and provide external connections to and from these sections.

This drawing provides detailed information concerning design specifications, operating conditions, dimensions, connections, plates and gaskets, plate arrangement diagram and key, bill of material and special notes.
Page 28
6.2. Plate Arrangement Diagram Configuration of the Diagram The plate heat exchanger is designed to perform a duty (or duties) by arranging the plates in a specific sequence. This arrangement is represented schematically by the plate diagram shown on the customer drawing. The schematic represents the fluid flows by heavy lines with arrows and the plates by thin vertical lines.
Page 29
Figure 18: Typical plate arrangement diagram Along the top of this diagram is a listing of each plate required, showing the hand of each plate (Right or Left), the direction the gaskets face (Head or Follower) and the plate punch code (blanking designation). The punch code indicates which ports are open and allow flow.

RECEIVING of EQUIPMENT 7.1. Receiving Check The APV GPHE is typically shipped fully assembled, skid mounted and wrapped in protective plastic. Other packaging methods could include an open box or seaworthy packaging. See Figure 28. Upon receipt of the equipment, check all received items against the packing list for damage or missing parts.
Page 36
Figure 28: Shipping methods Figure 29: Typical nameplate 8.2. Foundation The foundation pad for industrial heat exchangers should be level and sized correctly for the outline of the frame. It must also be of adequate strength to support the full operating weight of the equipment.
Page 37
The line flexibility may be accomplished by use of expansion joints. If the APV GPHE has liquid connections on the follower, it is important that the compressed dimension is checked against the customer drawing before the pipes are connected.
Page 38
Figure 31: Follower movement 8.5. Pressure Pulsation and Vibration Piston pumps, gear pumps, valves, etc. must not be able to transfer pressure pulsations or vibrations to the plate heat exchanger as this can cause fatigue fracture in the plates. The use of pressure dampers in the pipeline is recommended to minimize this effect. 8.6.

When assembling a GPHE, all components must be sufficiently supported to prevent damage. The following steps are recommended to safely assemble an APV GPHE. These instructions refer to the components illustrated in Figure 1 in Section 4.0. It is recommended that assembly be performed at the intended final location of the GPHE.

installed in the proper sequence, that gaskets are fully or securely seated in their grooves, and there is no debris on the plates or gaskets. Clean the gasket sealing surface with a lint free cloth. Push each plate firmly against the previous one. Use special care with mechanically retained gaskets (gaskets clipped to the plates) to avoid dislodging them (Figure 39).
Check that the tie bar threads are free from damage. Clean the tie bar threads and liberally apply the applicable anti-seize compound along the area where the nuts will travel during tightening. Also apply the compound to both sides of the plain washer under the tie bar nut.
Page 46
Never tighten a GPHE which is under pressure. Never tighten a GPHE while piping is connected to the follower or connector grids. 3) Install the remaining side tie bars located between the ports (if applicable) and tighten them evenly until the plate dimension is the same at all installed tie bars. 4) Starting with the top installed pair of tie bars (1 and 4), continue tightening equally in 6mm (1/4 in.) increments until the platage dimension measures approximately 5% greater than the final dimension.
Page 47
Opening-up of higher pressure sections can cause leakage of that section. The robustness of the APV GPHE is also linked with the percentage division of plate counts in various sections.
Note: Pneumatic pressure tests using air, helium or nitrogen are not recommended. Pneumatic tests shall only be used when the APV GPHE cannot be completely drained of the hydrostatic test water and the remaining traces of test water are detrimental to the operating fluid(s).
Never tighten the heat exchanger below the minimum pitch. A heat exchanger which has been in storage for more than five (5) years should be inspected by a qualified SPX FLOW representative prior to preparing it for operation. INSTALLATION, OPERATION and MAINTENANCE MANUAL | 49...
STARTUP, OPERATION and SHUTDOWN 11.1. General Prior to startup, ensure the equipment is correctly assembled and the piping connected properly. Also, check that the plates have been compressed to the correct dimension specified on the customer drawing (Figure 42 and refer to Section 9.0). Correct assembly and tightening are required for safe startup and operation.
Page 51
Figure 43 shows an example of a typical system configuration for a liquid/liquid (Cold/Hot) application. Each circuit (Cold and Hot) has a similar configuration. The exact piping, control arrangement, design and installation is outside of SPX FLOW’s scope and responsibility.

Page 53
Startup process (suffix C is for Cold liquid circuit; H is for Hot liquid circuit) STEP COLD MEDIUM HOT MEDIUM Start pump (1C) Open inlet valve (2C) slowly, building inlet pressure at a rate of less than 1.7 bar (25 psig) every 10 seconds. Monitor (7) and record pressure in at least these intervals.
ShutDown Process (suffix C is for Cold liquid circuit; H is for Hot liquid circuit) STEP COLD MEDIUM HOT MEDIUM Close valve (2H) slowly, reducing pressure from operating to atmospheric at a rate of less than 1.7 bar (25 psig) every 10 seconds.
Sudden changes in the operating pressures and temperatures must be avoided. Shock cooling of the APV GPHE may cause leakage, due to sudden contraction of the sealing gaskets. Temperature and pressure cycling must be limited to the rate changes specified in Section 11-1 (startup and shutdown).
5) When using hydraulic tightening tools, ensure that each tie bar is loosened approximately equally (+/- 3mm or 1/8 in.) during opening. 6) When the plate pack is fully released and the tie bars removed, the APV GPHE can be opened by pushing the follower back against the end support.
Figure 44: Precaution for removal of plates During maintenance, secure the follower to the end support to prevent accidental rolling. Separate the plate pack carefully to avoid damaging the gaskets or the plates. Remove the plates by sliding the bottom portion of each plate backwards and then sideways off the top bar and then removing from the frame (Figure 44).
It is recommended to lay the plate on a flat surface during brush cleaning to avoid the risk of bending the plate. If the APV GPHE is heavily fouled, care must be taken to remove all debris from the gasket sealing surfaces when the heat exchanger is reassembled. Any debris will most likely lead to sealing failures.
After some time of standing, flush the solution with clean water. If the APV GPHE is to be out of operation for a long period of time, it is advisable to empty it, separate the plates, and clean the equipment. After cleaning, lightly re-clamp the plate pack and cover it to protect from dirt and UV light.

Excess Nitric acid can seriously damage NBR and other rubber gaskets. Several alternatives to Nitric Acid can be used, e.g., Phosphoric Acid up to 5% maximum concentration and 85°C (185°F) maximum temperature. Consult SPX FLOW to find all the alternative CIP regimes possible.
GPHE must be opened and the APV DuoSafety plate pair separated. Carefully check the inside surfaces for traces of the product/ liquid processed in the APV GPHE. If visual inspection of the surface is difficult (e.g., because the product is transparent) then it is recommended that indicator dye is sprayed onto the inside surface of the plate pairs.
Page 62
Overheating the plates can cause discoloring and damage. PLIOBOND glued gaskets can be loosened and removed by placing the gasketed plate in water at 100°C (212°F). Cleaning To remove remaining traces of old adhesive, grease, or dirt from gasket grooves, use a solvent such as Acetone or a commercial gasket removal product.
Page 63
Attachment of Paraclip Gaskets Non-glued Paraclip gaskets are an alternative to glued in gaskets that simplifies on site re-gasketing. The gaskets have a series of small nubs or projections molded into the underside of the gasket. These projections fit into corresponding slots located around the periphery of the plate and port areas, securing the gasket to the plate (Figure 46).

the gasket to the plate (Figure 47). When the plate heat exchanger is tightened, a complete and secure seal is assured. To attach an EasyClip gasket, the gasket is laid out on the plate in its correct position. The projections are firmly pressed into the corresponding slots in the plates. After installing the gasket, the plate may be immediately installed in the frame in preparation for tightening.
areas, securing the gasket to the plate (Figure 48). When the plate heat exchanger is tightened, a complete and secure seal is assured. To attach a Double Clip gasket, the gasket is laid out on the plate in its correct position. The projections are firmly pressed into the corresponding slots in the plates.
The in-line filter, when supplied, needs to be cleaned at regular intervals (Figure 49). The frequency depends on the content and size of debris in the fluid being filtered. An increase in the pressure drop over the APV GPHE indicates the need for cleaning. Clean the in-line filter in this sequence: ...
Figure 49: In-line filter 12.11. Preventative Maintenance A preventative maintenance program will help keep APV GPHE’s running at optimal levels. The frequency of the maintenance inspections is dependent on a variety of reasons, some of which are: Production hours.
13.2. Power Tightening Equipment Pneumatic Wrench To facilitate the closing and tightening of large heat exchangers or plate heat exchangers containing a large number of plates, pneumatic tightening wrenches (single or dual wrenches) are available in two models. Table 2 shows the pneumatic power tighteners recommended for small heat exchangers with port opening <= 6 inch and large heat exchangers with port openings >...
The in-line filter mesh size is typically between 2.0mm (0.08 in.) – 2.5mm (0.1 in.) and is, dependent on the heat transfer plate gap. Where an in-line filter is purchased for an existing APV GPHE, please check whether the plate heat exchanger is prepared for the installation of an in-line filter. Additional modifications may be necessary.
Figure 52 or clamp lengths in Figure 53. A drip tray can be installed when the APV GPHE is insulated (see Section 13.6). The drip tray (Figure 54) has support blocks attached to the bottom surface of the drip tray and these blocks are attached beneath the plate heat exchanger feet with the drip tray resting on the floor.
For gaskets and plates see item numbers on APV GPHE plate arrangement diagram. On some APV GPHE plates, the last four digits of the item number are also stamped near one end of the plate. On some gaskets, the part number may be molded on the gasket.
