About Solstice by Honeywell

Solstice by Honeywell

Honeywell is an established technical leader in the development of  ‘4th Generation’ fluorine-based refrigerants (HFOs or hydrofluoroolefins) for the worldwide commercial and industrial refrigeration industry.

We have been at the forefront to develop safer, non-ozone depleting alternatives to older refrigerant technology (CFC and HCFC refrigerants), in compliance with global legislation for their phaseout.


  • are safe to use
  •  have significantly lower GWP than HFCs
  • are much lower than all Directives require – the GWP reduction of some Honeywell products can be up to 99.6%
  • have better performance and are more energy efficient when compared to refrigerants they are intended to replace
  • use the same technology as HFCs, so implementation and cost to serve are very simple: HFOs need only minor (if any) changes to the technology customers currently use and the differences in implementing and maintenance are minimal
  • are a global solution, as they are effective in different ambient temperatures
