In a statement the company said that the exemption “further demonstrates the environmental benefits of Solstice zd refrigerant, which has a global warming potential (GWP) of 1 (equal to carbon dioxide), significantly lower than the GWP of traditional hydrofluorocarbon (HFC) refrigerants, and an order of magnitude lower than the GWPs of many hydrocarbons.”
“Manufacturers of centrifugal chillers need a refrigerant that offers both outstanding heat transfer performance and superior environmental properties. Solstice zd offers exactly that — it is VOC-exempt, has an ultra-low GWP, and is nonflammable,” said Rajiv Banavali, chief technology officer for Honeywell Fluorine Products.
