Eco-friendly Refrigerants

Refrigerant Usage Ban

Refrigerant Usage Ban

Many of the refrigerants that used to be in common use are affected by usage bans in the Montreal Protocol and by the phasedown specified in the F-gas Regulation. This is because such refrigerants have an ozone depletion potential (ODP > 0) and/or are environmentally harmful greenhouse gases that contribute to global warming (high GWP value).

Alternative Eco-Friendly Refrigerants


But there are alternatives: the group of synthetic hydrofluoroolefin (HFO) refrigerants, such as R-1234ze, and the group of natural refrigerants, such as ammonia (R-717) or carbon dioxide (R-744), for example.

Reduce CO2 Footprint

Reduce Carbon Footprint

Eco-friendly refrigerants considerably reduce the direct emissions and thus the CO2 footprint of chillers and heat pumps. Furthermore, HFOs combine low direct emissions with low indirect emissions if highly efficient oil-free radial turbo compressors are used.

Refrigerant chemical properties

Refrigerant Properties

Each refrigerant has its own specific chemical and physical properties that distinguish it for its particular area of application.
