HG CO2 T compressors, transcritical

The compressors are used for transcritical and subcritical applications in supermarkets, commercial and industrial plants, and heat pumps.

• Gas-cooled, semi-hermetic reciprocating compressors
• Operating pressures of up to 130 bar
• Conceived for transcritical CO2-systems:
   Standstill pressures LP 100 bar / HP 150 bar
• Highest efficiency in the market with an energy efficiency (EER)/coefficient of performance (COP) of more than 1.85 (50 Hz [1450 rpm], evaporation -10 °C, gas cooler outlet 35 °C/90 bar, superheat 10 K)

Special features
• Highest compressor efficiency for lowest operating costs
• Long-life compressor design
• Reliable and safe oil supply through pump lubrication
• Low oil throw-off
• Good operating characteristics with low vibration, low pulsation, and low operating noise
• Broad limits of application and large frequency range (20-70 Hz) for a wide variety of uses
• Pressure relief valves for the suction and pressure area
• Long experience with transcritical CO2 compressors (since 1993)

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
