2.11.2 Internal Heat Recovery (option W2 / W3)
A plate heat exchanger is installed for heat recovery.
Generally water is used as the heat transfer medium. This must conform to the specifica-
tion given below.
The water may not be used as drinking water.
If a leak occurs, oil can contaminate the cooling water.
The manufacturer should be consulted before another type of heat transfer
medium is used.
