The system preferably has a plurality of storage reservoirs, the refrigerant being withdrawn from the transfer vessel into one of said plurality of storage reservoirs based on said qualitative analysis. In operation, a single connection between the transfer vessel and the recovery device is sufficient.Field of SearchAssembling, charging, or repairing of refrigeration producerSeparating or preventing formation of undesirables WITH INDICATOR OR TESTER Withdrawing or adding refrigerant from or to normally closed system WITH MEANS FOR CHARGING CLOSED REFRIGERATION PRODUCING SYSTEM Carbon containing compound (e.g., vinylchloride, etc.) | |
