Citing the globally mandated transition away from ozone-depleting refrigerants, York International Corporation announced it will stop offering new chillers using HCFC-123 refrigerant beginning November 15, 2004.
York Americas president Iain Campbell noted that HCFC-123, an ozone-depleting chemical, is designated by the Montreal Protocol and the U.S. Clean Air Act as a transitional refrigerant. It is to be used for only a limited time, to enable manufacturers to develop centrifugal chillers utilizing refrigerants with zero ozone-depletion potential (ODP). "The legislated phase-out of HCFC refrigerants began in 2004," said Campbell, "and the demand for HCFC-123 chillers is falling globally. York believes the time has come to complete the transition by ceasing to offer new HCFC-123 chillers. Today, we have a full line of zero-ODP chillers utilizing HFC refrigerants, which have no phase-out schedule."
