R-410A Refrigerant

R-410A Refrigerant

R-410A is a binary blend of HFC-32 and HFC-125. It has no chlorine content, no ozone depletion potential, and only a modest global warming potential. R-410A is the leading substitute for R-22 in residential and light commercial air-conditioning and heat pump systems. It exhibits higher pressure and refrigeration capacity than R-22 and should be used only in systems specially designed for R-410A. R-410A will require the use of POE lubricants.
