  gas 134a   Applications: gas134a is used as refrigerant in automobile airconditioning, household and commercial refrigerant applications. It can also be used as aerosol, flame retardan, and blowing agent in pharmaceutical, agro-chemical, cosmetics and cleaning sectors. Replaces CFC12 in auto air conditioning and in residential, commercial and industrial refrigeration systems. New equipment.Commercial Refrigeration: Performs well in small hermetic systems. Centrifugal Chiller Refrigerants: Used in many new chiller designs. Air Conditioning and Heat Pumps: Used in large screw chillers. EPA SNAP Approved. UL Listed.  When retrofitting R12 systems to R134a, it is necessary to replace the existing lubricant with POE oil, except in some automotive retrofit applications, which require PAG oil. In most cases, the mineral oil or alkylbenzene oil levels must be reduced below 5% of the new POE charge. Check with OEMs for any specific recommendations regarding oils or procedures. Remove as much of the existing lubricant as possible, add POE, and run the system on R-12 for some time. When the residual oil concentration is appropriate, remove R12, replace the filter-drier,and charge R-134a.
