Suction gas-cooled HG and air-cooled HA compressors offer a full capacity range of innovative, modern compressor technology with 2-, 4-, 6- and 8-cylinders. Suitable for all current refrigerants, as well as HC and CO2. For the EX range, GEA is the first European manufacturer to offer compressors certified according to ATEX machine category 2.
HA Single-Stage Compressors
Semi-hermetic HA compressors are primarily used for deep-freezing. Suction gas intake is done directly into the compressor. Motor is cooled by an integrated ventilation unit.
HG CO2 Compressors Subcritical
Based on our current semi-hermetic product range, with its outstanding advantages and features, as well as the derived and long-used basic range, there is now a perfectly matched compressor series available for use with CO2 in sub-critical cascade systems.
HG CO2 Compressors Transcritical
Semi-hermetic transcritical CO2 compressors using R744 as natural refrigerant. The compressors are ideally suited for use in transcritical CO2 applications.
HG Single-Stage Compressors
The HG model series consists of state-of-the-art classical suction gas-cooled compressor technology. Assurance of effective lubrication by an oil pump, application of exchangeable electrical motors, as well as manufacture of very solid and rugged compressors is ensured. For new advancements in efficiency, GEA has now updated its entire HG range of semi-hermetic compressors.
