CO2 scroll compressors come in three ranges, one for medium-temperature applications and two for low-temperature operations. The series of 4MTL transcritical models ranges from 5 to 50 hp; the series of 4MSL subcritical models ranges from 3 to 15 hp., 50 Hz supply frequency. The line-up of 4-cylinder Stream semi-hermetic compressors for CO2 transcritical applications is the ideal solution for the medium temperature section of booster systems. This range is designed for maximum standstill pressures of 135 bar at high side and 90 bar at low side. Refrigerant flow and heat transfer have ...
