There is one compressor unit that consists of two identical compressors.
The unit consists of two semi hermetic reciprocating compressors with freshwater cooled condensers. One compressor has capacity to maintain the requested temperature in all the rooms.
The compressors are stand-by for each other.
The provision plant is painted in RAL5001.The weight of plant unit is about 450kg.
Additionally there will be fan coolers in each refrigerated room and one common control panel for these. This control panel is supplied for bulkhead-mounting.
The plant has been designed for cooling of the following rooms:
1 pc freezing room -25ºC approx. volume: 16.0m3
1 pc freezing room -25ºC approx. volume: 15.4m3
1 pc freezing room -25ºC approx. volume: 15.4m3
1 pc cooling room +4ºC approx. volume: 16.7m3
1 pc cooling room +4ºC approx. volume: 17.5m3
1 pc cooling room +4ºC approx. volume: 17.5m3
1 pc dry provision room +5ºC approx. volume: 27.5m3
1 pc dry provision room +5ºC approx. volume: 26.9m3
1 pc thawing room +5ºC approx. volume: 21.5m3
