Semi-Hermetic Compressors HG CO2 Compressors Subcritical

Based on our current semi-hermetic product range, with its outstanding advantages and features, as well as the derived and long-used basic range, there is now a perfectly matched compressor series available for use with CO2 in sub-critical cascade systems. They are particularly suited to supermarket applications and industrial cooling systems.

Important Information

  •  Gas-cooled semi-hermetic piston compressor
  • Subcritical CO2 operating conditions 
  • Displacement from 1,6 to 48,2 m³/h (50 Hz)
  • Operating pressures of up to 51 bar (15°C)
  • Designed for subcritical CO2: LP 40 bar (27 bar) / HP 55 bar
  • Highest efficiency at low temperature applications (to < -15°C)

Special Features

  • High compressor efficiency for low operating costs
  • High durable compressor design
  • Wide operating limits and wide frequency range for different applications
  • Continuously variable speed control system available as a plug & play accessory
