 WILMINGTON, Del., Sept. 14 /PRNewswire/ -- DuPont (NYSE: DD) has announced commercial availability of the first non-ozone-depleting alternative blend for commercial refrigeration applications such as the transportation, storage and retail sale of food.
 Suva HP62 is a nonflammable substitute that replaces R-502, a chlorofluorocarbon (CFC)-based product that has been in use by the commercial food industry for over 30 years. Suva HP62 is a blend of hydrofluorocarbon (HFC)-125, HFC-143a and HFC-134a. Its formulation provides the industry with the closest performance match to R-502. The product can be used in new or existing equipment.
 Reliable refrigeration is critical to the preservation of our food supply, said Joseph P. Glas, vice president and general manager-Fluoroproducts. About 75 percent of our food is refrigerated at some point between harvest and the dinner table. Suva HP62 will make the transition away from CFCs easier for end users because it offers an environmentally acceptable, performance match for R-502-based equipment.
 DuPont also produces Suva HP80 and HP81 -- products specifically designed for easy, low cost retrofits in existing R-502 equipment.
 In the U.S. alone, about two million grocery and supermarket food display cases rely on refrigeration, much of it using R-502. Approximately 1,000 new supermarkets were built last year. With the imminent phaseout of CFCs, the use of Suva HP62, and the HP series in general, offers the industry environmental solutions for their near-term and long-term needs.
 Suva HP62 is the ninth product in DuPont's family of alternative refrigerants, which includes low or non-ozone-depleting options for major refrigeration and air conditioning applications.
 Key companies working with Suva HP62 include global compressor manufacturers Copeland Corporation, Bristol Compressors, Inc., Tecumseh, Carlyle Compressor Company and Bitzer; food display case and rack manufacturers Hussmann Corporation, Tyler Refrigeration Corporation, Hill Refrigeration and Kysor/Warren; and leading transport refrigeration companies Thermo King and Carrier Transicold.
 The product is scheduled for use by The Kroger Company, American Stores Company, Safeway, Inc., Giant Food, Inc., and Jitney Jungle Stores of America, Inc., in addition to other national and regional supermarket chains.
 Suva HP62 is manufactured at DuPont's Deepwater, N.J., facility. Its components are sourced from the company's plants in the U.S. and Japan.
 DuPont produces the broadest range of CFC alternatives with four families of products -- Suva refrigerants, Formacel foam expansion agents, Dymel propellants and Axarel cleaning agents.
 DuPont will phase out the production of CFCs in developed countries by year-end 1994. The company has invested more than $500 million in the development and commercialization of CFC alternatives.
