Danfoss Multi Ejector SolutionTM, consists of a CTM 6 High Pressure valve and an AK-PC 782A controller. This solution makes CO2 refrigeration systems economically competitive with the HFC systems at all ambient temperatures by improving COP in comparison to standard parallel compressor systems. CO2 systems with Multi Ejector SolutionTM can be installed in any climate delivering lower energy consumption than i.e. R404A. It removes the CO2 equator entirely. CTM 6 HP is designed for CO2 systems with parallel compression to lift a part of the gas from MT suction and mix it with the gas coming from the gas cooler at medium pressure level.
