R-407A R-407A is a mixture of gasses used as a refrigerant. It is a zeotropic blend of difluoromethane (HFC-32), pentafluoroethane (HFC-125) and 1,1,1,2-tetrafluoroethane (HFC-134a).〔(MSDS for R407A )〕 R-407A was developed as a close match to R-22's capacities and flow rates, making it well suited as an energy efficient retrofit for R-22 in medium and low temperature refrigeration systems for supermarket and food storage applications, but not for air conditioning systems or those with flooded evaporators.〔(Arkema, Inc. - Forane Refrigerants )〕 It must be used with synthetic oils.〔(BOC Ltd. - List of traditional HFCs )〕 Its global warming potential is 2107〔http://www.arkema-inc.com/index.cfm?pag=1598〕 ==References==
