GEA Bock’s new generation of subcritical compressors GEA Bock HGX44e CO2 for the natural refrigerant carbon dioxide (R744) boosts a minimum of 6% higher CO2 compressor efficiency compared to customary compressors on the market, according to the company, which allows operating costs to be significantly reduced. The world premiere with the simultaneous market launch of the subcritical CO2 compressors took place at GEA Bock’s trade fair appearance at EuroShop 2020 in February in Düsseldorf.
In addition to the significantly higher compressor efficiency, the new HGX44e CO2 series with its four model variants sets further standards for subcritical CO2 compressors: These include extended operating conditions, e.g. optimized 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, adapted maximum permissible operating pressure (LP/HP 30/55 bar) and the excellent performance spectrum with swept volumes from 27.7 to 49.2 m3/h (50 Hz) and corresponding refrigerating capacity from 51 to 90 kW.
“Our HGX44e compressors for the natural refrigerant CO2 offer planners, investors, and operators’ clever solutions for industrial low-temperature applications where functionality, cost-effectiveness, and climate protection go hand in hand. We call this “The °Clever Art of Cooling,” Manuel Fröschle, product manager Natural Refrigerants at GEA Bock GmbH in Frickenhausen said.
