Copeland Stream Semi-hermetic R-744 Transcritical CO2 Applications

Stream series of 4 cylinder CO2 compressors is the ideal solution for R744 booster systems. It is characterized by a design pressure of 135 bar. Refrigerant flow and heat transfer have been optimized for best performance. All compressors are equipped with CoreSense technology and offer the possibility to diagnose system-related problems faster or even before they occur.
