Future-proof, reliable, cost- and energy-efficient - the new generation of subcritical compressors GEA Bock HGX44e CO2 for the natural refrigerant carbon dioxide (R744) sets a milestone especially for industrial low temperature applications in cold stores and in the food industry.

The main advantage for the user: A minimum six percent higher CO2 compressor efficiency compared to customary compressors on the market. "This allows operating costs to be significantly reduced," says Manuel Fröschle, Product Manager Natural Refrigerants at GEA Bock GmbH in Frickenhausen. "Our new series, which has been successfully launched on the market, scores points with customers above all through improved process efficiency with minimized energy costs, while at the same time expanding the range of applications and uses. And all this with the highest reliability thanks to our proven GEA Bock CO2 compressor design". The world premiere with simultaneous market launch of the groundbreaking subcritical CO2 compressors took place at GEA Bock's trade fair appearance at EuroShop 2020 in February in Düsseldorf.

The °Clever Art of Cooling - advantages and benefits that set standards

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. In addition, the refrigeration and air-conditioning specialists from Frickenhausen have optimized the running characteristics of the new compressors: Minimized noise, vibrations and pulsations ensure a high level of user comfort as well as a high level of system safety and reliability with minimized maintenance requirements.

"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," explains Manuel Fröschle.
