ABSTRACT:
The present invention is directed to a self-contained refrigerant recovery and purification system capable of removing gaseous refrigerants from a disabled refrigeration unit for cleaning acid and impurities from the refrigerant so that the refrigerant can be reused or saved rather than being lost to the atmosphere or otherwise wasted. In addition to the feature of saving, cleaning and returning the refrigerant to the repaired refrigeration unit, the present invention can be used as a temporary condensing unit, or for clearing oil restrictions from lines in the refrigeration unit with a high-pressure build-up feature, or as a vacuum pump.
