CARE 30 is a blend of iso-butane (R600a) and propane (R290) developed to replace R12 and R134a:

Primarily for use in small commercial refrigeration and air-conditioning systems that have traditionally used R12.

Operates at similar pressures to R12 or R134a.

Possesses similar volumetric refrigerating effect to R12 and R134a.

Can be used in an R12 or R134a compressor or a specific CARE 30 compressor.

Can be used with R12 or R134a heat exchangers and expansion devices.

Compatible with most common refrigeration materials and lubricants.
