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

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
