Honeywell has announced the launch of new lower-global-warming- potential (GWP) products for applications ranging from supermarket refrigeration to industrial cooling. The new products expand Honeywell’s Solstice® line of hydrofluoro-olefin (HFO) refrigerants, blowing agents, aerosol propellants and solvents. Honeywell’s offerings include:
• Solstice zd (R-1233zd): a non-flammable HFO refrigerant with a GWP equal to 1, for use in low pressure centrifugal chillers. Trane, a leading air conditioner manufacturer, has announced that it will use Solstice zd in its new Series E CenTraVac large capacity centrifugal chillers in Europe, the Middle East and other markets.

• Solstice ze (R-1234ze): an HFO refrigerant that can be used in equipment that traditionally used R-134a (i.e., chillers, heat pumps, appliances and refrigeration equipment). Solstice ze offers a GWP of less than 1.

• Solstice N13 (R-450A): an HFO blend for chillers, medium-temperature applications such as supermarket display cases and self-contained refrigeration units that require a non-flammable refrigerant solution. Solstice N13 is designed to replace R-134a and offers a GWP that is 60 percent lower than the GWP of R134a.

• Solstice N40 (R-448A): an HFO blend for low- and medium-temperature refrigeration equipment such as supermarket freezer cases or transport refrigeration. Solstice N40 is designed to replace HCFC R-22 and HFC R-404A, both for new equipment and retrofit, and offers a GWP that is 66 percent lower than R404A.
