Liquid Ejector is a part of the CO2 Adaptive Liquid Management (CALM), Danfoss' solution to handle liquid in all types of transcritical CO2 systems in all climates. Due to higher suction pressure, Liquid Ejector, together with Adaptive Liquid Control (ALC), enables lower energy consumption and better utilization of evaporators, resulting in operational savings. Improved system performance results in fewer or smaller compressors and a minimal suction accumulator. Liquid Ejector is designed for CO2 transcritical systems to pump the CO2 liquid from the low point in the suction accumulator back to the receiver resulting even in 8 bar pressure lift after mixing with gas coming from the gas cooler. The Liquid Ejector, AK-PC pack controllers, AKCC case controllers, and AK-SM system manager comprise the Danfoss CALM
