|Composition||r-125 (50%) r-32 (50%)|
|Type||HFC Near-azeotropic blend|
|ASHRAE safety classification||A1-non-toxic and non-flammable|
*GWP value for 100-Year time horizons according to IPCC 2007 Fourth Assessment Report.
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.
