Honeywell announces commercial launch of HFO refrigerant range

Honeywell has announced the commercial launch of four new HFO products, including its first HFO blends, designed to replace R134a and R404A

Refrigerant manufacturer Honeywell has launched HFO-based replacements for a range of applications, including its first commercially available blends in its Solstice range. The latter, R450A and R448A are designed to offer low-GWP replacements for R134a and R404A respectively. 

The launch comes hot on the heels of rival DuPont launching its R450A and R448A products at Chillventa in October.

George Koutsaftes, global business director for Honeywell’s Fluorine Products business said: “Honeywell is committed to continuing to invest in the development and introduction of new offerings, to make it easier for industry to adopt and use alternatives to higher global warming potential refrigerants.”

The range comprises:

  • Solstice zd (R1233zzd): a non-flammable HFO with a GWP equal to 1, for use in low-pressure centrifugal chillers. Chiller specialist Trane has already announced that it will use the refrigerant in its CenTraVac large capacity centrifugal chillers in Europe and the Middle East.
  • Solstice ze (R1234ze (E)) an HFO refrigerant that can be used in equipment that traditionally used R134a (i.e., chillers and refrigeration equipment). Solstice ze offers a GWP of less than 1.
  • Solstice N13 (R450A): an HFO blend for chillers, as well as medium-temperature applications such as supermarket display cases and self-contained refrigeration units that require a non-flammable refrigerant solution. It is designed to replace R134a and offers a GWP that is 60 per cent lower than the GWP of R134a.
  • Solstice N40 (R448A): an HFO blend for low- and medium-temperature refrigeration equipment such as supermarket freezer cases. It is designed to replace R22 and R404A, and offers a GWP that is 66 per cent lower than R404A. In supermarket trials in the US and Europe, the company said, Solstice N40 demonstrated three per cent lower energy consumption in low-temperature applications and 5 to 16 per cent lower energy consumption than R404A in medium-temperature applications.
