The invention is a device for recovering contaminated chlorinated fluorocarbons (CFCs) from refrigeration apparatus, and purifying them for reuse. The CFC can be received in either vapor or liquid state, and is distilled and purified first in vapor state. The vapor is then superheated, compressed and condensed to a liquid state and is further purified in the liquid state. Heat of the condensed liquid stream is applied to help vaporize incoming CFC to heat the vapor so as to prevent recondensation, and to superheat the vapor prior to compression.
