Refrigeration & Air Conditioning Compressors
Factory manufactured, assembled, tested and packed in Frickenhausen, Germany
With the current series of units, GEA-BOCK offers you a comprehensive range from 5,4 to 281.3m³/h displacement.
In terms of capacity, the units are having a wide range of refrigeration capacity ranges from 1.77 KW to 162.0 KW for chiller applications & 1.02 to 57.6 KW for freezer applications (2HP to 95HP Compressors)
Two Compressor Variants
- - Suction gas cooled compressors (2 to 95HP) for both chiller and freezer applications. (HG RANGE)
- - Air cooled compressors (2 to 20HP) specifically for freezer/low temperature applications. (HA RANGE)
Suction gas cooled compressors have it motors cooled by means of suction gas which flows through the motor.
Air cooled compressors have it's motor cooled by means of air stream mechanically by means of external fan motor connected to compressor body with fan guard, no liquid injection kits, solenoids, modules or electronic needed when applying freezer application.
Compeititors when using R22 for the freezer application they have to use these expensive kits, and link to their control circuits.
