UL-CO2 compressors (subcritical)
UL-HG CO2 subcritical
UL-HG CO2 LT subcritical (100bar/100bar)
HG CO2 and HG CO2 LT compressors, subcritical The compressors are used in both cascade and booster UL-CO2 systems in applications for supermarkets, commercial and industrial cooling systems. UL-HG CO2 • Gas-cooled, semi-hermetic reciprocating compressors • Subcritical UL-CO2 operating conditions (deep freezing) • Operating pressures of up to 51 bar (tc = 15 °C) • Conceived for subcritical UL-CO2 systems: Standstill pressures LP 30 bar / HP 55 bar • High efficiency in deep freeze applications (to < -15 °C) UL-HG CO2 LT • Gas-cooled, semi-hermetic reciprocating compressors • Subcritical UL-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 UL-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
