ABSTRACT:
A device for detecting and removing contaminants from charged refrigeration systems comprising conduit means temporarily communicating the high pressure liquid line of the system with the lower pressure suction line, the conduit means having means for visually determining the moisture content within the refrigerant charge, filter means for removal of the contaminant and a pressure differential means for allowing the refrigerant to return into the system in low pressure gas form. Means are also provided for selectively introducing into the conduit means a sufficient amount of new charge to replace the contaminated charge which is removed from the system by the filter means.
