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).[http://www.refrigerants.com/msds/nri-r407a.pdf MSDS for R407A] {{webarchive|url=https://web.archive.org/web/20110208070231/http://refrigerants.com/msds/nri-r407a.pdf |date=2011-02-08 }} 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.[http://www.arkema-inc.com/index.cfm?pag=1598 Arkema, Inc. - Forane Refrigerants] {{webarchive|url=https://web.archive.org/web/20110320024053/http://www.arkema-inc.com/index.cfm?pag=1598 |date=2011-03-20 }} It must be used with synthetic oils.[http://www.gas2010.com/traditional-hfcs BOC Ltd. - List of traditional HFCs] Its global warming potential is 2107.{{cite web |url=http://www.arkema-inc.com/index.cfm?pag=1598 |title=Forane® 407A |accessdate=2011-03-22 |url-status=dead |archiveurl=https://web.archive.org/web/20110320024053/http://www.arkema-inc.com/index.cfm?pag=1598 |archivedate=2011-03-20 }}
