Chlorine free substitutes for special applications

Due to the limited market for systems with extra high and low temperature applications, the development of alternative refrigerants and system components for these has been pursued less intensely.

In the meantime, a group of alternatives for the CFC R114 and Halon R12B1 (high temperature), R13B1, R13 and R503 (extra low temperature) have been offered as replacements. On closer examination, however, the thermodynamic properties of the alternatives differ considerably from the previously used substances. This can cause costly changes especially with the conversion of existing systems.
