R401A Refrigerant

Product Summary





A blend of R22, R152a, and R124 intended for retrofitting R12 refrigeration systems. The pressure and system capacity match R12 when the blend is running in a 10°F to 20°F evaporator, and there is typically an 8°F temperature glide in the evaporator.

WARNING: This product can expose you to chemicals including Chloroform, Methyl chloride, Chloroethane (Ethyl chloride), and Vinyl Chloride, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to

Product Applications & Replacements

Direct expansion refrigeration and air conditioning systems designed for R12 or R500; good success in any size system, minor adjustment of controls needed. Discharge pressure increases compared to R12, also slight increase in discharge temperature, however the increases are not as severe as some other retrofit blends. There is a drop in capacity at lower temperatures. R152a content, an HFC, hurts the miscibility with mineral oil. It is recommended to change some of the oil to alkylbenzene unless the system is small and running at higher evaporator temperatures. Retrofitting R22 equipment to R410A is not recommended under any circumstances.
