3.1.4.6 Oil cooler

Fig.9:

Arrangement of the oil cooler

The GEA RedGenium heat pumps are equipped with an air cooled oil cooler.
The oil cooler is used for cooling the oil heated in the compressor in order to
ensure sufficient oil viscosity for supplying to the compressor.

The documentation of the oil cooler (acceptance certificate) is part of the
product documentation.
