CO2-Compressor (subcritical)
HG CO2 subcritical
HG CO2 LT subcritical (100bar/100bar)
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
