Copeland compressors for transcritical CO2 refrigeration

Date:

The Copeland line of 4 cylinder CO2 compressors is the solution for R-744 transcritical booster systems. It is characterized by a design operating pressure of 1740 psig (120 bar). Refrigerant flow and heat transfer have been optimized for superior efficiency. All compressors are equipped with CoreSense technology, offering faster system troubleshooting and protection from problems before they occur.
