Semi-Hermetic Compressors HG CO2 Compressors Transcritical

Semi-hermetic transcritical CO2 compressors using R744 as natural refrigerant. The compressors are ideally suited for use in transcritical CO2 applications.

Important Information:

  • Gas-cooled semi-hermetic piston compressor
  • Displacement from 6,2 to 38,2 m³/h (50 Hz)
  • Operating pressures of up to 130 bar
  • Designed for transcritical CO2:
    LP 100 bar / HP 150 bar
  • Highest efficiency in the market with COP of more than 1,85 (50 Hz [1450 U/min], evaporating -10°C, gas cooler outlet 35°C/90 bar, superheat 10 K)

Special Features:

  • Highest compressor efficiency for low operating costs
  • High durable compressor design
  • Reliable and safe oil supply through pump lubrication 
  • Good operational characteristics with low vibration, low pulsation and low noise level
  • Wide operating limits and wide frequency range for different applications
  • One of the biggest capacity ranges
    [> 38 m³/h (transcritical)]
  • High stand still pressure for best operating conditions 
  • Longest CO2 compressor experiences in the market (since 1993)
  • Applications: Heat pumps, commercial refrigeration, industrial refrigeration
