GEA Bock HGX44e CO2 compressors

The new generation of subcritical compressors GEA Bock HGX44e CO₂ for the natural refrigerant carbon dioxide (R744) is suitable for industrial low-temperature applications in cold stores, and in the food industry. The main advantage for users is a minimum 6% higher CO₂ compressor efficiency, compared to customary compressors on the market. The series is designed to reduce operating and energy costs through improved process efficiency, while expanding the range of applications and uses.

Alongside providing higher compressor efficiency, the series has four model variants and features extended operating conditions, such as optimised hot gas defrosting and an extended frequency and temperature range with evaporating temperatures from -50 to -15°C and condensing temperatures up to +15°C.

The compressors also feature an adapted maximum permissible operating pressure (LP/HP 30/55 bar) and a good performance spectrum with swept volumes from 27.7 to 49.2 m³/h (50 Hz), and corresponding refrigerating capacity from 51 to 90 kW. Refrigeration specialists from Frickenhausen have optimised the running characteristics of the compressors, with minimum noise, vibrations and pulsations to provide a high level of user comfort as well as a high level of system safety and reliability with minimised maintenance requirements.
