R-407c is a ternary blend of HFC-32, HFC-125 and HFC-134a. It has no chlorine content, no ozone depletion potential, and only a modest direct global warming potential. R-407c serves as an HFC refrigerant replacement for R-22 in various air-conditioning applications, as well as in most refrigeration systems.
