Care 30
CARE 30 is a refrigerant consisting of a blend of isobutane and propane developed to replace dichlorodifluoromethane and 1,1,1,2-tetrafluoroethane. It is primarily for use in small commercial refrigeration and air-conditioning systems that have traditionally used R-12.
Compatibility
It operates at similar pressures and possesses similar volumetric refrigerating effect to R-12 and R-134a. It can be used in a R12 or R134A compressor or a specific CARE 30 compressor. It can be used with R-12 or R-134a heat exchangers and expansion devices. It is compatible with most common refrigeration materials and lubricants.Comparison
