HG CO2 compressors, subcritical

The compressors are used in both cascade and booster systems in applications for supermarkets, commercial and industrial cooling systems.

• Gas-cooled, semi-hermetic reciprocating compressors
• Subcritical CO2 operating conditions (deep freezing)
• Operating pressures of up to 51 bar (tc = 15 °C)
• Conceived for subcritical CO2 systems:
   Standstill pressures LP 40 bar (30 bar) / HP 55 bar
   High efficiency in deep freeze applications (to < -15 °C)

Special features
• High compressor efficiency for lowest operating costs
• Long-life compressor design
• Broad limits of application and large frequency range for a wide variety of uses
• Reliable and safe oil supply through pump lubrication
• Good operating characteristics with low vibration, pulsations, and low operating noise
• Pressure relief valves for the suction and pressure area

Important information
• CO2 applications require a new kind of system and control
• They do not represent a general solution for substitution of F-gases
• The notes on handling CO2 compressors in the instructions for assembly must be followed
• We specifically point out that all information in this brochure is based on our current level of knowledge and may change at any time due to further development
