Product Announcement: Honeywell’s Solstice Launched as Environmentally-friendly Refrigerant

 

Honeywell has unveiled SolsticeN41 (provisional R-466A), a nonflammable and lower global-warming-potential (GWP) refrigerant for use in stationary air conditioning systems.

Honeywell claims that once on the market, Solstice N41 will be the lowest GWP, nonflammable, R-410A replacement refrigerant available worldwide. The refrigerant has received a provisional number and a preliminary A1 designation from the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE).

It is expected to be available commercially in 2019.

The product comes after years of research and development by Honeywell scientists who set out to address one of the most vexing regulatory and safety challenges facing the HVAC industry.

Honeywell claims that early testing indicated that switching to Solstice N41 would require minimal changes to equipment and no additional training for installation and repair technicians. Preliminary data indicates that the refrigerant may allow OEMs to easily convert from R-410A.

With numerous regulations (including Europe’s F-Gas regulation and the internationally adopted Kigali Amendment to the Montreal Protocol) requiring the phase down of high-global-warming products, the HVAC industry has been looking to replace the current industry standard refrigerant, R-410A, with an energy efficient, nonflammable, and lower GWP solution with a similar or better performance. Solstice N41 is the only refrigerant that combines those attributes.

Solstice N41 joins the family of Solstice products which Honeywell developed to accelerate the transition from away from materials with high GWPs.
