In a device to recover refrigerant from a refrigeration circuit and subsequently recharge the refrigeration circuit with the recovered refrigerant, the condenser and refrigerant storage means of the device is a cooled tank. Refrigerant vapor inputs the base of the tank through a one-way check valve so that the entering vapor is cooled as it bubbles through any liquid refrigerant in the tank and then condenses on the cool walls of the tank.
