Semi-hermetic compressor HG


The Bock HG (Hermetic Gas-cooled) range of semi-hermetic compressors offers traditional suction gas-cooled compressor state of the art technology.

These compressors of the highest quality standard excel in their running comfort, easy maintenance, efficiency and reliability. Suitable as standard for conventional or chlorine-free HFC refrigerants.

The HA (Hermetic Air-cooled) range, specially engineered by GEA Bock, is available for deep-freezing applications, in particular for use with the refrigerants R22 and R404A.


Those compressors are efficiency optimised models. By technical optimisations the motor-efficiency, gas flow and efficiency of the valve system are improved.


With the Pluscom series we offer you small-capacity compressors for shops and counter installation with extremely compact dimensions, super-quiet running and absolute top quality. Special highlight: fully variable speed control with frequency converter technology mounted directly on the compressor.
