BOCK - HGX44e CO2 4-Cylinder Subcritical Compressor

HGX44e CO₂ 4-Cylinder Subcritical Compressor

For a wide range of commercial and industrial applications. The BOCK CO₂–suitable 4-cylinder subcritical compressor range: HGX44e CO₂.

The HGX44e CO₂ is the latest and biggest compressor of the BOCK subcritical compressor series and uses 4 cylinders, running in capacity stages of 27.7-49.2 m³/h up to 50 Hz. Basically, our subcritical HGX series includes 4 different model sizes with 17 capacity stages from 1.6 to 49.2 m³/h (50 Hz) and cooling capacities from 2.7 till 90 kW.

The BOCK subcritical compressors are ideal for applications like supermarkets or commercial and industrial cooling in general. All our subcritical CO₂ compressors are designed for variable speed control and are optimally adapted for the use of natural refrigerant R744. This guarantees a flexible cooling capacity adjustment for different requirements.

The HGX44e CO₂ is your tailor-made, cost-saving, reliable and durable partner for nearly the most mobile industrial and commercial R744 applications.
