DuPont Refrigerants Helps German Supermarket Take Environmental Lead


June 13, 2006

DuPont News, - The European deadline for the phase-out and replacement of ozone-depleting hydrochlorofluorocarbon (HCFC) refrigerant gases is fast-approaching and the consequence for those operating refrigeration and air conditioning systems using HCFC refrigerants is clear. The recharge of these systems with hydrofluorocarbon (HFC) refrigerant solutions -- commonly referred to as ‘retrofit’ -- must begin now. For the refrigeration and air conditioning sector, this represents both a tremendous challenge and an opportunity requiring imminent action.

“As a global leader in the refrigerants industry, DuPont is in the pole position to lead this transition, initially by informing both contractors and end-users about the coming R-22 phaseout and existing alternatives,” said Joachim Gerstel, market development manager, DuPont™ ISCEON® 9 series refrigerants, DuPont Europe, Middle East and Africa. The recent addition of the ISCEON® 9 Series means DuPont now offers the leading, easy-to-use and non-ozone-depleting retrofit refrigerants for HCFC equipment.

German supermarket group REWE took the environmental lead and recently converted from R-22 to DuPont™ ISCEON® MO29 refrigerant at their store in Munster, Germany, as part of a pilot project. Requiring essentially no technical modifications to the supermarket’s existing refrigeration systems, the retrofit took place without interrupting business.

Munster Store Manager Harald Van Dillen, said, “This is a great advantage to retailers, as food remains undamaged and sales continue without interruption. This saves us both precious time and money.”

The ISCEON® 9 Series blends were used in refrigeration and air-conditioning equipment, including low temperature freezer rooms and pack systems, cold rooms, roof top packaged reverse cycle heat pumps, split air-conditioning systems and control computer rooms. In the majority of these cases, the ISCEON® 9 Series family of refrigerant blends were used with existing lubricating oils and did not require significant modifications to the systems and demonstrated improved energy efficiency, leading to substantial cost savings for the supermarket retailer.

“We appreciate working with the European refrigeration Industry and helping them meet their sustainability goals,” said Mark Baunchalk, global business manager, DuPont Refrigerants. “We’re very excited about the potential for ISCEON® 9 Series refrigerants to help the global industry meet its needs to move from CFCs and HCFCs to HFC alternatives.”
