Recovery Subcooler (MT69) Refrigerant from CPS assists in the transformation of high temperature/pressure vapor- to low liquid- refrigerant. Designed for use with any recovery machine, the MT69 transforms molecules of hot refrigerant gas into molecules of cooler refrigerant liquid. It also transforms molecules of cold refrigerant liquid into a warm refrigerant gas. The MT69 was designed to save time and money when doing refrigerant recovery work. It makes any recovery machine perform like a heavyweight.
