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).^[1] 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.^[2] It must be used with synthetic oils.^[3] Its global warming potential is 2107.^[4]
