HCFCs (Hydrochlorofluorocarbons) were used for many years as replacements for CFCs (Chlorofluorocarbons). HCFCs however, like CFCs, have an Ozone Depletion Potential (ODP) and their use was banned in many applications including in new equipment from the year 2000. The use of virgin HCFCs was permitted for maintenance and servicing purposes until 2010 when a complete ban was enforced. A 5-year exemption exists for service and maintenance of refrigeration and air conditioning systems to use reclaimed or recycled HCFC (see Legislation section for more details). Companies using HCFC refrigerants have either replaced their equipment or converted equipment to run using a non ozone depleting alternative.
A number of HCFC replacements are currently available, including the DuPont™ ISCEON 9 Series range. For tailored advice on the best refrigerant for your application please contact us.
