DuPont reaches settlement with refrigerant reseller

DuPont reaches a settlement with a refrigerant reseller in Italy in a dispute concerning patented R-422D retrofit refrigerant used in commercial refrigeration and building air conditioners

DuPont and Star Refrigeration Glasgow, UK, has announced that they have reached a settlement with a refrigerant reseller in Italy in the context of a court action concerning patented R-422D.

In a statement, it said: “DuPont is the sole licensee under a Star Refrigeration patent covering R-422D, a non-ozone-depleting refrigerant broadly used to retrofit and service commercial refrigeration and building air conditioning equipment. Product R-422D marketed by DuPont under the trademark ISCEON® MO29 is part of the DuPont™ ISCEON® family of non-ozone depleting retrofit refrigerants.

These refrigerants have become the leading choice in Europe to enable equipment owners to continue to operate equipment designed for HCFC-22 refrigerant despite the ban of virgin HCFC-22 for service in the European Union.

“DuPont is committed to protect intellectual property for refrigerants such as DuPont™ ISCEON® MO29. The protection of intellectual property is critical to ensuring our continued investment in new technologies and products for the cooling marketplace” says Diane Iuliano Picho, global business manager DuPont Refrigerants.”
