This refrigerant has been prepared by mixing R32 + R125 in equal quantity. It belongs to HFC group of refrigerants. Its ODP is zero and GWP is 1800. It is neither toxic nor flammable. Therefore it comes under the safety class of Al. Its boiling point at atmospheric pressure is —52.7°C. It is mixable with polyolester (POE) oil. As it catches the moisture rapidly from the air, therefore it may be noticed that it may not come in contact with air while charging it into the machine. This refrigerant was prepared for the replacement of R22 gas but due to its less cooling capacity and extremely high working pressures, it could not be successful. Therefore it has been used only in those machines which specially have been designed for this refrigerant.
