HG CO2 and HG CO2 LT compressors, subcritical
The compressors are used in both cascade and booster CO2 systems in
applications for supermarkets, commercial and industrial cooling systems.
HG CO2
• 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 (HGX44e CO2: 30 bar) / HP
55 bar
• High efficiency in deep freeze applications (to < -15
°C)
HG CO2 LT
• Gas-cooled, semi-hermetic reciprocating
compressors
• Subcritical CO2 operating conditions (deep freezing)
•
Operating pressures of up to 64 bar (tc = 25 °C)
• Two motor version (ML
and S) for wide frequency range and operation on higher condensing
temperatures
• Conceived for subcritical CO2 systems with high stand still
pressures:
Standstill pressures LP 100 bar / HP 100
bar
• High efficiency in deep freeze applications (to < 0
°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
