Care 30

CARE 30 is a refrigerant consisting of a blend of isobutane (R-600a) and propane (R-290) developed to replace dichlorodifluoromethane (R-12) and 1,1,1,2-tetrafluoroethane (R-134a).Industrial Gases: Care 30 BOC: The Linde Group, Producer of Care 30. Retrieved on 5 March 2016. 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.
