ABSTRACT:
A method and apparatus for cleaning and filtering contaminants from the refrigerant in a refrigeration system does not permit any gaseous refrigerant to escape to the atmosphere during repair of the system. A tank containing a disc of filter material has piercing valves connected to an inlet and an outlet. The tank and filter are connected to the contaminated system by the piercing valves, the contaminated refrigerant passes through the filter and is retained in the tank. Once the system is repaired, the refrigerant passes from the tank and filter into the system, but the tank and filter remain connected thereto while the system is operated. The tank and filter are removed after a time sufficient to clean the refrigerant.
