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:
- medium temperature refrigeration,
- low temperature refrigeration.
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.
