R407H for retrofitting from R22 and R404A/R507
R-407H is a blend composed of HFC R32, HFC R125 and HFC R134a.
In terms of capacity and efficiency it is similar, and can therefore represent a possible alternative, to the old HCFC R-22 refrigerant, although it is not a direct "drop-in" type retrofit product.
It is not an ozone-depleting gas and has a lower GWP than R404A.
Being a zeotropic mixture it should be noted that in the vapor phase the original composition of the mixture is altered, with possible consequences on the plant; it is therefore necessary to load the mixture exclusively in the liquid phase.
Main features:
- HFC ternary blend (ODP=0)
- GWP (1.495) lower than other low temperature refrigerants (e.g. R-404A, R-507)
Safety classification A1 (non-toxic and non-flammable).
Applications:
- Medium and low temperature commercial and industrial direct expansion refrigeration
- Supermarkets
- Food, Chemical and Pharmaceutical Industry
- Refrigeration cells
Lubricants:
When R407H is used in the conversion of R-22 systems, some system modifications will need to be made, such as lubricant replacement.
Mineral oils and alkylbenzene lubricants are immiscible with R407H; therefore, they will have to be replaced with other lubricants (e.g. POE); however, consult the system manufacturer for the necessary recommendations in this regard.
