HCFC Transitional Refrigerants

HCFCs (Hydrochlorofluorocarbons) have been used for many years and more recently as replacements for CFCs (Chlorofluorocarbons). HCFCs however, like CFCs also have an Ozone depletion Potential (ODP) and their use is already banned in many applications and in new equipment. The use of virgin HCFCs for servicing and maintenance of refrigeration and air conditioning equipment will be banned in European Union countries from 01/01/2010 under EC regulation 2037/2000 (see legislation). Many companies have now replaced their HCFC refrigerants either by selecting new equipment or by converting existing equipment to non ozone depleting alternatives.

A number of direct replacements for HCFCs are available and we recommend you look at the DuPont^TM ISCEON® 9 Series Refrigerant range to find the appropriate one for your application.

For further specific advise on individual applications please go to the IDS contact page and send us details of the application you are looking to replace.

IDS R22
Chlorodifluoromethane

R22 is a single component HCFC refrigerant. It is used across a wide variety of applications including residential and commercial air conditioning, medium and low temperature commercial, food storage and industrial and transport refrigeration systems.

R22 is also used as a component in other HCFC blends.
The use of R22 and other HCFCs are subject to phase-out under EC Regulation 2037/2000 and it will be illegal to use virgin product from 01/01/10

IDS recommend the use of DuPont^TM ISCEON® MO29 (R422D) as a direct replacement for R22
in a wide range of refrigeration and Air Conditioning applications.

Please contact IDS to discuss the specific application in more detail. Product information, MSDS case studies and conversion guidelines can be found in the download section.
