Replaces CFC-12 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 R-12 systems to R-134a, 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 R-12, replace the filter-drier, and charge R-134a.
HFC-134a is used as refrigerant in automobile air-conditioning,
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.
