Page 15: Function
Description 3 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 16: Multi-Section
3 Description 3.4 Multi-section A multi-section heat exchanger can be set up by using connection plates. An example of multi-section configuration is when a media needs to be heated in one stage and then cooled down in the next stage. Each of the connection plates can be configured by selecting different corner connections such as single, double, pass-through or blind. -
Page 17: Multi-Pass
Description 3 3.5 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. For some units, a partition plate is required to support the unholed ports in the turning plates. - Page 18 3 Description 200000423-1-EN-GB...

Page 19: Installation
4 Installation 4.1 Before installation To consider before installation • Before connecting any piping, make sure all foreign objects have been flushed out of the piping system that should be connected to the heat exchanger. • Before start-up, check that all the tightening bolts are firmly tightened and that the plate pack has the correct measurements. -
Page 20: Requirements
4 Installation 4.2 Requirements Space Please refer to the delivered PHE drawing for actual measurements. 1. Free space is required for lifting plates in and out. 2. Free space is required under the lower tightening/locking bolt for maintenance. 3. Supports for the guiding bar may be needed. 4. - Page 21 Installation 4 CAUTION Turning of the connections will damage the gaskets on the end plate and cause leakage. Fit the pipes so that no tension is transferred to the heat exhanger. Nozzle loads are not permitted. Pipes connected to the pressure plate and to the connection plates must allow ±1% of the distance from the connection to the frame plate (see the assembly PHE drawing).

Page 22: Lifting
Use of other attachment points or strap load directions than those described are not allowed. If the heat exchanger is not supplied with lifting devices from Alfa Laval, the corresponding equipment must be selected and the same attachment points must be used. -
Page 23: Raising
Installation 4 4.4 Raising This instruction is valid when raising the heat exchanger after delivery from Alfa Laval. Only use a strap approved for the weight of the heat exchanger. Follow the principle of the instruction below. CAUTION The straps shall be long enough to be able to rotate the heat exchanger without obstruction. - Page 24 4 Installation Lift the heat exchanger off the timber beams. Lower the heat exchanger into a horizontal position and place it on the floor. 200000423-1-EN-GB...

Page 25: 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 on the name plate. 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 26 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 45 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 Closing on page 39. 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.
