Forane® 427A

Arkema Forane® Refrigerant logo

Forane® 427A is a simplified and cost-effective retrofit solution for existing R-22 installations in a large range of applications. Forane® 427A is the closest match to R-22 in terms of performances, mass flow rates, and operating pressures over the whole range of temperatures and has one of the lowest GWP among R-22 retrofit solutions. Due to its similar behavior in operation and its close thermodynamic properties in comparison to R-22, Forane® 427A is the only retrofit that 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).
