R407C Refrigerant

The refrigerant R407C is a zeotropic refrigerant mixture consisting of three components with very different boiling temperatures. This results in a temperature shift during the phase change, which is very well suited for heat pump systems.

R407C was developed as a replacement refrigerant for R22 in air conditioners and heat pumps. The pressure level of both refrigerants is very similar.

The refrigerant R407C is non-flammable, non-toxic and colorless. R407C has a global warming potential ( GWP ) of more than 1 (GWP = 1774).  

R407C has an ODP (Ozone Depletion Potential ) value of 0. 

It is suitable for heat pumps with positive displacement compressors and direct evaporation. It is  classified in safety class A1 according to ISO / ASHRAE  .

With its GWP of more than 150, R407C is governed by F-gas Regulation 517/2014. Thus, it is affected by the phase-down scenario provided for in the  F-Gas Regulation .
