Single-stage Compressors R134a

• GEA Bock offers a compressor variant

optimised especially for use with the

refrigerant R134A

• The compressors are particularly

suited for normal refrigeration in

supermarket applications as well as in

cascade systems in conjunction with

CO2

Special features

The compressors can be

adapted ideally to the

individual demands because

of the special design of the

different components

Compressors optimised for

the specific characteristics of

R134a achieve a higher

efficency and increase the

annual capacity of the

refrigeration plant

The energy consumption of

Bock compressors is

continually improved by

technical optimisations
