The refrigerant R407F is a zeotropic refrigerant mixture consisting of three components with different boiling temperatures. This results in a temperature glide of 6.4K at the phase change. R407F is suitable as a replacement and drop-in refrigerant for R22 existing refrigeration systems. R407F is particularly suitable for low and medium temperature applications. For single-stage refrigeration systems in the deep-freeze area, attention must be paid to the final compression temperature. Due to increased cylinder head temperatures, the use of a cylinder head fan may be necessary. Here, the technical specifications of the compressor manufacturers should be observed.
The refrigerant R407F is non-combustible, non-toxic and colorless. R407C has a global warming potential ( GWP ) of more than 1 (GWP = 1825).
R407F has an ODP (Ozone Depletion Potential ) value of 0.
R407F is classified in safety class A1 according to ISO / ASHRAE .
With its GWP of more than 150, R407F is governed by the F-gas Regulation 517/2014. Thus, it is affected by the phase-down scenario provided for in the F-Gas Regulation.
