In October, more than 190 countries agreed to an historic amendment to the Montreal Protocol that would phase down the use of high global-warming-potential (GWP) hydrofluorocarbons (HFCs) in many applications, including supermarket refrigeration. Japan’s revised Fluorocarbons Law enacted in April 2015 set the HFC phasedown target of condensing units and stationary refrigeration units at GWP 1,500 by the year 2025.
These commitments mean that supermarkets need an HFC alternative that is available today, offers ease of conversion, and performs as well as, if not better than, previous solutions. Honeywell offers a new generation of products, called hydrofluoropolefins (HFOs), which are being adopted globally, that meet these goals. Marketed under the Solstice brand, an excellent solution for supermarkets is available: Solstice N40 (R448A).
