What is the advantage of using Forane® 427A instead of R-404A for the retrofit of existing R-22 equipment?
When retrofitting existing R-22 equipment with Forane® 427A, no modification of the installation is necessary which is not the case with R-404A requiring in most cases a replacement of the expansion valve, redesign of the liquid line, and sometimes modification of the heat exchangers or compressors. Forane® 427A is consequently a much simpler retrofit solution it has a much lower GWP than R-404A.
