Full scale marketing of new refrigerant gases is underway in Japan, as DuPont-Mitsui Fluorochemicals begins to sell its Isceon hydrofluorocarbon (HFC) gas mixed refrigerants on a full scale basis this spring.

The Isceon refrigeratns have no ozone depleting potential and can be used as substitution for hydrochlorofluorocarbon (HCFC) and chlorofluorocarbon (CFC) in Japan, where the use of CFC had already been banned completely by the end of 1995. Initiatives are ongoing for the total abolishment of HCFC by 2020.

The Isceon refrigerant can provide a solution with its ‘retrofit’ feature which slightly remodel or revise existing refrigeration or air conditioning facilities, exclusively using HCFC and CFC refrigerants, to allow these facilities to use Isceon replacements. With almost the same refrigerant ability as that of HCFC or CFC, these new refrigerants do not however, destroy the ozone layer when discharged to the atmosphere.

DuPont’s Isceon range of refrigerants are produced at the companys Dordrecht plant in the Netherlands and refilled in small quantities into cylinders at the DuPont-Mitsui Fluorochemicals plant at Shimizu in Japan, where if demand continues to increase, the company will consider production at its Shimizu site.

A market of around 1,000 tonnes was formed in Europe in 2006 where use has already started to become widespread, and the apparent reason behind the full scale marketing in Japan is that the approval by the high pressure gas safety low is expected to be given this spring.
