Refrigerants and the Environment

General concern about the effect of human activities on the global environment has grown rapidly. There is widespread anxiety over the influence of CFC's and other greenhouse gases on the ozone layer, some of which are used in refrigerating systems.

The environmental concerns led to a ban of the further use of CFC's like R11, R12, R502 and the life-span of HCFC's such as R22 is coming to an end soon.

Today some new refrigerants and blends of HCFC's/HFC's are introduced to the refrigeration market.  However, the only refrigerant with a zero Ozone Depletion Potential (ODP), a zero Global Warming Potential (GWP), superior thermodynamic properties and worldwide availability is ammonia (NH3).  FES Systems has an enviable reputation gained in using ammonia as a refrigerant for more than 100 years.

The use of ammonia as a refrigerant in refrigeration systems means an important contribution to the preservation of the ozone layer. Moreover, ammonia quickly breaks down into its natural components nitrogen and hydrogen, thus excluding the possibility of a risk to the climate through a direct greenhouse effect.

For that reason, we are convinced that, because of its efficiency

 and environmentally friendly properties,

ammonia is an important refrigerant of the future.
