Honeywell Specialty Materials has secured global rights from DuPont that allow Honeywell to sell R-422D, a replacement for R-22 in refrigeration and air-conditioning systems.

R-422D is a non-ozone-depleting hydrofluorocarbon (HFC) refrigerant that is an efficient and cost-effective retrofit solution for replacing ozone-depleting R-22 in existing systems. Honeywell will sell R-422D under the Genetron refrigerants brand name.

"This global agreement allows Honeywell to provide additional solutions for its customers all over the world who must meet regulatory requirements to phase-out ozone-deplete substances," said David Diggs, global business director for the refrigerants business of Honeywell Fluorine Products.

Under the Montreal Protocol, all signatory nations have agreed to phase-out the use of ozone-depleting substances, including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). The European Union has aggressively implemented this change. In 2003, it banned new systems from using R-22, a HCFC refrigerant. Additionally, in 2010 the production of R-22 for refrigeration and air-conditioning applications for service of existing equipment will also be prohibited. Owners of R-22 based equipment will either need to service the equipment with recycled/reclaimed R-22, use a retro-fit fluid such as R-422D or replace the equipment. Other countries are also implementing the phase-out of R-22.

Honeywell Specialty Materials is based in Morristown, N.J.
