Abstract: A purge apparatus for removing foreign non-condensable gases from a refrigeration system including a closed vessel adapted to receive the foreign gases together with a portion of the refrigerant from the high pressure region of the system. The vessel is cooled to condense the refrigerant, and a float actuated electrical switch is provided within the vessel to open a first valve for discharging the condensed refrigerant upon the refrigerant reaching a predetermined level, and a second valve for venting the non-condensable gases to the atmosphere upon a drop in the refrigerant level. The discharged condensed refrigerant is utilized to cool the vessel by evaporating the same in an area about the outer walls of the vessel, and then returned to the low pressure region of the system.
