Forane® 427A: the closest retrofit for R-22 at any level of temperature, from air conditioning to medium and low temperature refrigeration.

Forane® 427A is a new 100% HFC blend from Arkema offering an easier retrofit for existing R-22 installations.

R-22 is an HCFC and hence subject to the regulations of the Montreal Protocol. While the use of recycled R-22 will be totally banned in Europe from January 1st 2015, Forane® 427A is your long-term, retrofit solution.

Forane® 427A can be used in a large range of applications:
  • air-conditioning,
  • medium temperature refrigeration,
  • low temperature refrigeration.
Forane® 427A has been designed to offer the closest match to R-22 in term of performances as well as regarding the mass flow rates and operating pressures in both air conditioning and refrigeration. Due to its similar behavior in operation, Forane® 427A is the only retrofit that can be used in equipments designed for R-22 without requiring any changes on the installation (no need to change the expansion valves, liquid lines, condensing units or any other costly parts of your system).

Forane® 427A is non-toxic and non-flammable with an A1 ASHRAE safety classification, has zero ODP and one of the lowest GWP (2138) among R-22 retrofit solutions.

As Forane® 427A is a 100% HFC blend, it is consequently compatible with Polyolester (POE) lubricants. However, one specificity of Forane® 427A is its ability to tolerate a high residual amount of original oil in the POE lubricant (good oil return up to 10-15% of residual AB or mineral oil). Therefore, only one drainage of the system’s oil is necessary which makes for a simplified retrofit procedure. In some cases, it has been noticed that Forane® 427A has been used without changing the original oil if the system has an oil separator and reliable oil return.

Forane® 427A is the most cost-effective solution for the retrofit of R-22 installations and has been used successfully in a variety of industries for over seven years:
  • Commercial and domestic air conditioning: chillers, rooftop units, split systems, heat pumps, etc.
  • Commercial refrigeration and food-processing sector : supermarkets, warehouses, cold rooms, etc.
  • Industrial refrigeration.

Forane® 427A is assigned to following product groups:
