Under this program, said Wolf, "Trane HCFC-123 chillers will emit 0.5 percent or less refrigerant annually or Trane will provide the refrigerant to the customer at no cost."

He stated, "This leak-tight warranty is provided to the client at no cost for the first five years of ownership for all new centrifugal chillers, starting in September of this year. And, if the equipment is covered under a Trane service contract, the leak-tight warranty covers the equipment for its entire life."
