Replacement Refrigerant for R22

Replacement refrigerant for R22 in direct evaporation systems for low-temperature refrigeration, normal cooling and air conditioning.

The information in this publication discusses alternative refrigerants:

R422D (MO29)

R417A (MO59)

R422A (MO79)

R438A (MO99)

There is currently no general obligation to convert equipment that is operating with R22 or R22-containing refrigerants to an al- ternative refrigerant. As long as the system has no leaks and does not need to be topped up with additional refrigerant, it may continue to be used without any restrictions. If, however, a decision has been taken to convert to an alternative refrigerant, it must be kept in mind that the compressors will then be subject to greater loads and thus additional wear, which can result in a shorter service life.

Individualswith appropriate technical training, knowledge and experience can find information on the replacement refrigerant in our new brochure "Alternative Refrigerants - Information on use of R22" or dowload it on this website.
