A blend of R-32, R-125, and R-134a that has very similar properties to R-22 in low and medium temperature refrigeration applications. R-407A has the closest property match to R-22 in a low temperature retrofit project compared to other blends on the market; however, there is a 10°F temperature glide. Most new supermarket and refrigeration equipment has been built for an HFC such as R-404A, R-507, or R-407A. New systems built with R-407A must have POE lubricants, and retrofitted R-22 systems would need the residual oil changed to POE.

R410a
A blend of R-32 and R-125 that nearly forms an azeotrope, which means it has extremely low temperature glide and almost no fractionation potential. This blend has about 60% higher pressure than R-22 in air conditioning applications, and therefore should be used only in new equipment specifically designed to handle the pressure. Systems designed for R-410A will have smaller components (heat exchangers, compressor, etc.) to perform the same cooling job compared to R-22. R-410A will require POE lubricants. Retrofitting R-22 equipment is not recommended under any circumstances.
