ABSTRACT:
A refrigerant recovery and purification system is provided. A one-pass system removes refrigerant, filters and purifies it and condenses and stores the refrigerant in its liquid state for reuse. A collection tank is provided which separates the non-condensible gases, thereby eliminating pressure buildup in the storage tank. The non-condensible gases are vented back to the system to selectively provide positive pressure for vacuum relief. The system also includes an oil separator for refrigerant which has passed through the compressor with a feedback line to return the oil to the compressor.
