Semi-hermetic compressors optimised for the refrigerant R134a

Based on our current semi-hermetic product range, with its outstanding advantages and features Bock now presents you a compressor variant optimised especially for the use with the refrigerant R134a. Especially suited for normal refrigeration in supermarket applications, as well as in cascade systems in conjunction with CO2.

Special features

With technical optimisations we continually improve the energy consumption of our compressors. Because of the special design of the different components we can adapt the compressors ideally to the individual demands. Those compressors optimised for the specific characteristics of R134a achieve a higher efficiency and therefore increase the annual capacity of the refrigeration plant. The compressor of the type HG5 in R134a version will be available in October 2010. Other models will follow gradually during the course of 2011.

The refrigerant R134a

Especially in the area of normal refrigeration for supermarket applications numerous studies have shown that R134a as a refrigerant contributes to a very high efficiency of the system. Suitable refrigeration oils are ester oils, such as Fuchs Reniso SE55.
