R407C is a blend of non-ozone depleting HFC refrigerants (R32, R125 and R134a). It has similar properties and characteristics to R22 and is used across a wide variety of air conditioning applications. It is widely used for splits, VRF, and direct expansion water chillers.
As R407C is a blend it should always be removed from the cylinder as a liquid when charging the system.
R407C is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.
R407C can also be used to retrofit some existing R22 air conditioning systems, however, it will be necessary to carry out a number of oil flushes when changing to a POE
