DuPont™ ISCEON® refrigerants have proven to be the most cost-effective R-22 replacement refrigerants. In many cases, systems retrofitted with these refrigerants are operating with the same mineral oil or alkylbenzene lubricant that was used with the previous CFC or HCFC refrigerant, and have been shown to provide similar system performance as when operating with the previous refrigerant.
Using these retrofit guidelines, direct expansion (DX), residential and commercial air conditioning (AC), and medium- and low-temperature refrigeration systems containing R-22 can be easily and economically retrofitted. This allows existing equipment to continue operating safely and effectively for the remainder of its useful life.
