GEA Bock recently announced their new generation of subcritical compressors GEA Bock HGX44e CO2 for the natural refrigerant carbon dioxide (R744) specifically designed for industrial low temperature applications in cold stores and in the food industry. The new compressor brings a 6% increase in efficiency over other 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, 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”.

As a world premiere, 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.

The company says that in addition to the significantly higher compressor efficiency, the new HGX44e CO2 series with its four model variants brings extended operating conditions, such as 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 by minimizing noise, vibrations and pulsations, to 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,” explains Fröschle.
