New environmentally preferable refrigerant can replace high global warmers slated for phaseout.

Honeywell (NYSE: HON) announced today that the U.S. Environmental Protection Agency has added Solstice™ zd refrigerant, also known as 1233zd, to the list of materials exempted from volatile organic compound (VOC) regulations.

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.

Honeywell now offers Solstice zd as well as Solstice™ ze refrigerant and Solstice™ N-13 (a refrigerant blend) as cost-effective, energy-efficient and environmentally preferable alternatives to high-global-warming-potential refrigerants typically used in centrifugal chillers.

VOCs are organic compounds that break down quickly in the lower atmosphere and participate in chemical reactions that ultimately create tropospheric (ground-level) ozone, which is an irritant and a major component of smog. The EPA provided the VOC exemption for Solstice zd based on the material’s low photochemical reactivity and negligible contribution to the generation of ground-level ozone.

In addition to Solstice zd refrigerant, Honeywell's family of Solstice-branded products includes gaseous blowing agents, propellants and solvents based on Honeywell’s new hydrofluoro-olefin technology that helps customers lower their carbon footprint without sacrificing end-product performance. The products have been developed and are being commercialized by Honeywell’s Fluorine Products business, a leader in the manufacture and supply of non-ozone-depleting blowing agents for energy-efficient foam insulation.
