HG HC Semi Hermetic Compressors for Hydrocarbons

Hydrocarbons have established themselves as another natural alternative refrigerant besides CO2 in various applications, such a supermarket refrigeration.

Based on the HG series GEA offer a low cost compressor option for use with hydrocarbons. Due to the flammability of hydrocarbons the compressor has some safety related modifications and the design features include:

  • Special oil charge
  • Motor protection supplied separately for an external installation (eg in the switch cabinet)

Compressors in HC-design have the following features:
Durable driving gear, Thermal protection thermostat, Oil sump heater, Special oil charge, Motor protection INT69 G for installation in the switch cabinet Optimised for all hydrocarbon requests

Models available: HG12P, HG22e, HG34e, HG44e, HG7 and HG8
