Forane 407C

Forane 407C (R-407C) is a non-ozone depleting, zeotropic blend of HFC refrigerants R-32, R-125, and R-134a, and has been formulated to match the properties of R-22 closely in air conditioning applications. Forane 407C can be used to replace R-22 in new or existing R-22 residential and commercial air conditioning systems as well as non-flooded evaporator chillers. R-407C is completely immiscible with mineral oil and will require a complete oil change to POE when retrofitting an R-22 installation.  Like other R22 retrofits, R-407C is a high glide blend and is therefore typically not recommended for use in a system with a flooded evaporator.
