Page 11: Description
3 Description 3.1 Components Main components 1. Frame plate Fixed plate with a various number of portholes for the connection of the piping system. The carrying and guiding bar are attached to the frame plate. 2. Carrying bar Carries the plate pack and the pressure plate. 3.
-
Page 12
3 Description 7. Tightening bolts Compress the plate pack between the frame plate and the pressure plate. The bolts with bearing boxes are identified as tightening bolts. Remaining bolts are used as locking bolts. 8. Portholes Portholes through the frame plate allow the media to enter into or exit from the heat exchanger. -
Page 13
Description 3 • Nozzle cover Protection to avoid particles to enter into the heat exchanger during transportation. • Drip tray Depending on the type of fluid in the heat exchanger and the type of installation, a drip tray (drainage box) may be necessary to avoid injury to personnel and damage to equipment. -
Page 14: Name Plate
3 Description 3.2 Name plate The type of unit, manufacturing number and manufacturing year can be found on the name plate. Pressure vessel details in accordance with the applicable pressure vessel code are also given. The name plate is fixed to the frame plate, most commonly, or the pressure plate.

Page 16: Function
3 Description 3.3 Function The heat exchanger consists of a pack of corrugated metal plates with portholes for the input and output of the two separate fluids. The heat transfer between the two fluids takes place through the plates. The plate pack is assembled between a frame plate and a pressure plate and compressed by tightening bolts.
-
Page 17: Multi-Pass
Description 3 3.4 Multi-pass Multi-pass sections can be created by using turning plates with 1, 2 or 3 unholed ports. The main purpose is to change the flow direction of one or both fluids. An example of where multi-pass can be used is in processes that require longer heating periods if the media requires slower heating.

Page 21
Installation 4 Connections in the pressure plate It is important that the plate pack has been tightened to the correct dimension A (check against the PHE drawing) before the piping system is connected. When opening the heat exchanger, the pressure plate must be moved. Do not use fixed pipes or other parts like feet, fasteners etc. -

Page 27: Operation
5 Operation 5.1 Start-up During the start-up, check that there are no visible leakages from the plate pack, valves or piping system. CAUTION Before pressurizing the heat exchanger, it is important to ensure that the temperature of the heat exchanger is within the temperature range as stated in the PHE drawing. CAUTION If the temperature of the heat exchanger is below the minimum temperature for the gaskets prior to the service, it is recommended to heat the heat exchanger above this limit to avoid cold…

Page 28
5 Operation Check that the valve is closed between the pump and the unit controlling the system flow rate to avoid pressure surge. If there is a vent valve installed at the exit, make sure it is fully open. Increase the flow rate slowly. Open the air vent and start the pump. -
Page 29: Unit In Operation
Operation 5 5.2 Unit in operation Adjustments of flow rates should be made slowly in order to protect the system against sudden and extreme variations of temperature and pressure. During operation, check that media temperatures and pressures are within the limits stated on the name plate and the PHE drawing.

Page 31: Maintenance
Different methods can be used for cleaning (refer to Cleaning – Non-product side on page 31) or reconditioning can be performed at an Alfa Laval service center. After a long period of use, it can be required to regasket the heat exchanger.
-
Page 32
6 Maintenance WARNING The residuals after a cleaning procedure shall be handled according to local environmental regulations. After neutralization most cleaning solutions may be drained into the waste water system under the condition that the fouling deposits do not contain heavy metals or other toxic or environmentally dangerous compounds. -
Page 33: Opening
During manual cleaning, it is necessary to open the heat exchanger to clean the plates. NOTE Before opening the heat exchanger, check the warranty conditions. If in any doubt, contact the Alfa Laval sales representative. Refer to Warranty conditions on page 7.
-
Page 34: Opening Procedure
6 Maintenance 6.2.2 Opening procedure Shut down the heat exchanger. Close the valves and isolate the heat exchanger from the rest of the system. Drain the heat exchanger. NOTE Avoid vacuum in the heat exchanger by opening vent valves. Remove the protection sheets, if any. Dismantle pipes from the pressure plate so that the pressure plate are free to move along the carrying bar.
-
Page 35
Maintenance 6 Mark the plate assembly on the outside by a diagonal line. Measure and note the dimension. Loosen and remove the locking bolts. Identify them according to Bolt configuration on page NOTE Brush the threads of the tightening bolts with a steel wire brush and then grease the threads before loosening the tightening bolts. -
Page 36: Manual Cleaning Of Opened Units
6 Maintenance CAUTION To avoid hand injuries owing to sharp edges, protective gloves should always be worn when handling plates and protection sheets. Open the plate pack by letting the pressure plate glide on the carrying bar. If plates are to be numbered, do this before removing the plates.

Page 37: Deposits Removable With Water And Brush
Maintenance 6 WARNING Use proper protective equipment, such as safety boots, safety gloves and eye protection, when using the cleaning agents. WARNING Corrosive cleaning liquids. Can cause serious injuries to skin and eyes! 6.3.1 Deposits removable with water and brush Plates do not need to be removed from the heat exchanger during cleaning.

Page 38: Closing
Check that all the sealing surfaces are clean. Brush the threads of the bolts clean, using a steel wire brush or the Alfa Laval thread cleaner. Lubricate the threads with a thin layer of grease, e.g. Gleitmo 800 or its equivalent.
-
Page 39
Maintenance 6 If the plate pack has been marked on the outside, check this (see step on page 35 in Opening on page 33). If the plates are correctly assembled (A/B/A/B etc.), the edges form a “honeycomb” pattern, see picture. Press the plate pack together. -

Page 44: Glued Gaskets
Close the heat exchanger according to Closing on page 38. 6.7.3 Glued gaskets Use glue recommended by Alfa Laval. Separate gluing instructions will be delivered together with the glue. CAUTION Other glues than those recommended can contain chlorides that can damage the plates.
-
Page 45: Storage Of The Heat Exchanger
7 Storage of the heat exchanger Alfa Laval delivers the heat exchanger ready to be put into service upon arrival, if nothing else has been agreed. Nevertheless, keep the heat exchanger in the packing box until installation. If storing for longer periods of time, such as one month or longer, certain precautions should be made to avoid unnecessary damage to the heat exchanger.
-
Page 46: Taken Out Of Service
Closing on page 38. 7. Alfa Laval recommends a hydraulic test should be carried out. The media, usually water, should be entered at intervals to avoid sudden shocks to the heat exchanger. It is recommended to test up to the Design Pressure.
