Frogen® R-407C was developed by Frogen Ltd. to provide a non-ozone depleting substitute for Frogen® R-22 in a range of air-conditioning applications, as well as a variety of refrigeration systems. Because Frogen® R-407C is closely matched in performance with Frogen® R-22, it can also serve as a retrofit refrigerant fluid in applications which have previously used Frogen® R-22.
