Honeywell and Trane Technologies have joined force to accelerate the transitions to a next-generation, environmentally preferable refrigerant.

As part of the partnership, Trane will deploy and by field test Honeywell’s Solstice® N41 (R-466A) refrigerant at three difference US-based customer locations as part of a one-year field trial.

Trane is currently testing Solstice N41 at the Western Cooling Efficiency Center (WCEC) at the University of California to evaluate its performance with a Trane rooftop HVAC unit used in light commercial applications.

The trials will test compatibility with new equipment installations and retrofit conversions. Trane will closely monitor power and energy consumption and analyse the refrigerant characteristics to further assess Solstice N41 as a replacement for R-410A.

Commenting on the news, Randy Newton, Vice-President of Engineering at Trane Technologies, said, “As a global climate innovator who is leading the industry transition to next-generation refrigerants, we have invested more than $500m to identify safe, sustainable options.”

“Our continuous testing, research and development supports new technologies that improve the carbon footprint in support of our customers’ needs and contribute to our Gigaton Challenge.”

“As we evaluate refrigerants to replace R-410A, we seek to balance environmental impact, safety, efficiency, and affordability. We look forward to working with Honeywell to assess the feasibility of Solstice N41 as a safe option for the industry that could enable ease of transition to meet regulatory deadlines and help our customers meet their overall sustainability goals.”

Ken West, Vice-President and General Manager, Honeywell Fluorine Products, added, “Honeywell scientists devoted years of research and development to develop a non-flammable product that can replace R-410A in homes and small business as a near drop-in replacement within existing infrastructures, while providing reduced global warming potential coupled with similar energy efficiency.”

“Solstice N41 is a great option for both commercial and residential end users. This next step with Trane solidifies our confidence in moving toward industry adoption of R-466A.”
