Frogen® 404A

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