MAIN APPLICATIONS 

R-227ea is a hydrofluorocarbon (HFC) intended for replacing R-114 (CFC) whose production was stopped in 

the European Union on 12.31.1994. 

It is particularly suitable for air conditioning devices functioning in high temperature environments, high 

temperature heat pumps, and thermal collectors. 

R-227ea is also used as an extinction agent replacing "fluorocarbon-bromide" compound R-13B1 whose 

production was stopped in the European Union as of 31.12.1993. 

OILS 

Use a polyol ester (POE) oil. 

Check with Climalife regarding the viscosity of the oil selected for your application, and the miscibility with the 

fluid under consideration. 

PRECAUTIONS OF USE 

Refer to the Safety Data Sheet*. 

REGULATION 

In Europe, R-227ea recovery is mandatory as per regulation n° 842/2006. 

(Refer to regulations enforced in each country)
