A portable, refrigerant recycle/recovery/charging system comprising: a storage tank; a low pressure refrigeration system; and a housing. The housing includes liquid, vapor, pump and condenser sections. The liquid section has a liquid inlet, a liquid outlet and a liquid conduit connecting the liquid inlet and the liquid outlet where the liquid conduit includes a liquid flow control device and a liquid condition sensing device. The vapor section has a vapor inlet, a vapor outlet, and a vapor conduit connecting the vapor inlet and the vapor outlet where the vapor conduit includes a vapor flow control device and a vapor condition sensing device. The pump section has a pump inlet, a pump outlet, and a pump conduit connecting the pump inlet and the pump outlet where the pump conduit includes a pump. The condensing section has a condensing inlet, a condensing outlet, and a condensing conduit connecting the condensing inlet and the condensing outlet where the condensing conduit includes a condenser.
