Forane 427A (R427A) - the Easy R-22 Retrofit

Date: 20 March 2017
Forane 427A (R427A) is the Easy Retrofit when it comes to retrofitting many R-22 applications, including air conditioning, heat pumps, and low- and medium-temperature refrigeration.  Forane 427A (R427A) is closest match to R-22 in terms of performances and operating pressures and was developed to minimize the work necessary during an R22 retrofit.  Due to its similar behavior in operation and its close thermodynamic properties in comparison to R-22, Forane 427A (R427A) can be used in equipment designed for R-22 without requiring any changes to the installation (no need to change the expansion valves, liquid lines, condensing units or any other costly parts of your system).  Millions of pounds have been sold globally since 2005.
