R-22 Replaced By Arkema Forane 427A
CHEMMONITOR.COM - Forane 427A refrigerant was confirmed by Emerson Climate Technologies (the US) to be used for Copeland Discus compressors.
Forane 427A is designed by Arkema (France) to replace R-22, a refrigerant, contributing to the ozone-depletion.
It closely matches R-22 in respect of mass flow rate, performance and operating conditions. Moreover, the refrigerant is able to reduce the compressor discharge temperatures.
Forane 427A has one of the lowest GWP rates of 2138 among the main R-22 retrofits.
