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
