Semi Hermetic UL CO2 from 1,100 cfh

UL-HG CO2 compressors, subcritical
The compressors are used in both cascade and booster CO2 systems in applications for supermarkets, commercial and industrial cooling systems.
UL-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)

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
Certified by Underwriters Laboratories
Certified by Underwriters Laboratories The U.S. company Underwriters Laboratories Inc. (UL) is a nationally recognized test laboratory by the U.S. federal agency OSHA (Occupational Safety and Health Administration) that tests products and components for safety in accordance with the relevant standards. The awarding of a UL test mark is generally necessary for the North American market in order to be able to market and use technical products such as compressors.
