Heat exchanger PWT 510 / PWT 910 / Operation
7.9 Retooling
The plate heat exchanger is a modular and flexible tool that can be expanded or made smaller as required.
In other words, you can change the capacity of the device by simply increasing or reducing the number of
plates.
BEHNCKE GmbH is happy to make proposals and to supply the appropriate measurements to convert
plate heat exchangers in accordance with DGR 2014/68/EU.
For this purpose, disclosing the item number on the nameplate and the changes you want to make will
suffice.
In addition to the components needed for the conversion, BEHNCKE GmbH will also provide a detailed
description of how it should be carried out. Every adjustment will be archived by BEHNCKE GmbH so that
the latest condition regarding the converted or overhauled heat exchanger can be seen.
7.10 Replacement parts
The device type and the heat exchanger item number (information on the nameplate) must be stated on
the order form for replacement parts. To avoid incorrect deliveries, the following points must be observed:
•
For orders relating to embossed plates, you must give the correct model number of the heat
exchanger.
•
When ordering a complete seal set, giving the item number is sufficient.
•
When ordering an individual seal, the exact item number is required, which can be found on the
seal itself.
7.11 Dismantling and disassembling the heat exchanger
When dismantling and disassembling the heat exchanger, the applicable regulations for dismantling the
materials it consists of must be complied with (stainless steel, synthetic rubbers and unalloyed steel).

IMPORTANT!
If the heat exchanger is out of commission for an extended period, the
following points must be observed:
•
If water is in the circuits, shut off the valves and leave the heat
exchanger full so that the valves don't become obsolete prematurely.
•
If process fluids are in the circuits, it is recommended that you empty
and clean the heat exchanger and then tension it moderately.
IMPORTANT!
If the heat exchanger is subjected to sudden temperature fluctuations during
normal operations (especially from warm to cold), perhaps due to a sudden
shutdown, the device may drip temporarily; however, this will usually stop again
once the normal operating temperatures have been restored.
