Solstice refrigerants are Honeywell’s brand name on new HFO refrigerants that it produces. At the moment there are only two mainstream producers of HFO refrigerants in the world. The first being Honeywell and the second being the Chemours Company. HFOs are a new class of refrigerants that are aimed to have a significantly lower Global Warming Potential than their HFC counterparts. (HFC examples include R-134a, R-410A, and R-404A.)
HFO refrigerants are the products of the future and we will be seeing more and more on Honeywell’s Solstice product line. So far in 2015 there are six Solstice refrigerants that Honeywell has developed. You can visit their website by clicking here.
