HGX46 CO₂ T 6-Cylinder Compressor

HGX46 CO₂ T – the biggest one for reliable and powerful CO₂ transcritical applications

The latest and so far, biggest CO₂ compressor of the BOCK HG family is our HGX46 CO₂ T compressor.

The Bock HGX46 CO₂ transcritical compressor is available in swept volumes from 24.4 – 38.2 m³/h (50 HZ) and existing in versions S for frequency control and enlarged operational limits, ML for standard cooling and low temperature applications, as well as SH for heat pumps, high evaporation temperatures and with a different oil filling.

HGX46 CO₂ offers competitive EER efficiency values in comparison to other products on the cooling market. HGX46/345-4 CO₂ with an evaporating temperature of -10° C at 50 Hz, a gas cooler outlet temperature of +35°C/90 bar and a suction gas superheat of 10 K reaches a EER of 1.90.
