The gas R407H replace correctly the R404a ( the system must be completely emptied before being loaded with the new gas).
R-407H refrigerant The development of the new R-407H refrigerant is based on an HFC blend and proposes a great alternative to comply with all the necessary requirements of EC Regulation 517/2014 (F-Gas) to reduce the environmental impact of the systems of refrigeration, while allowing a quick and easy retrofit of existing R-404A / R-507 systems.
R-407H is a refrigerant designed for new installations and to replace R-404A / R-507 in high and medium temperature installations. For low temperatures, the discharge temperature must be studied. The cooling capacity of R-407H is similar to R-404A and R-507. The GWP of R-407H (1495 according to the latest publication of the EC Regulation F-Gas and 1371 according to Law 16/2013 Fluorinated Gas Tax) is approximately 62% lower than R-404A / R-507.
