Solution is a replacement for R-410A, with 67 percent lower global-warming-potential, superior energy performance and matching capacity

BRUSSELS, Belgium, September 11, 2018, 2018 – Honeywell (NYSE: HON) today announced the availability of Solstice^® L41y (R-452B), a reduced global-warming-potential (GWP) refrigerant designed to replace R-410A for reversible heating and cooling applications. The solution offers 67 percent lower GWP than R-410A, 5 percent higher energy efficiency and lower discharge temperature/pressure vs. R-32 that helps reduce capital costs for safety mitigation. Featuring efficiency and capacity to match R-410A, Solstice L41y is now commercially available including approved compressors for both chillers and heat pumps. This will allow equipment manufacturers to quickly transition R-410A equipment to a lower-GWP product, while minimizing redesign costs and capital expenditure. “Honeywell is working closely with leading global equipment and component manufacturers to optimize Solstice L41y for heat pump and chiller applications, where customers want to achieve high heating/cooling efficiency and water temperature while keeping the re-design costs low,” said Julien Soulet, vice president and general manager, Honeywell Fluorine Products Europe, Middle East and Africa. “The product is an immediately available solution for OEMs that cannot move directly to the latest generation long-term products such as Solstice L40X (R-455A), Solstice ze (R-1234ze) or Solstice zd (R-1233zd). With Solstice L41y, they gain compelling benefits such as fast and easy implementation, while allowing them to comply with tightening regulations. Most importantly, it helps manufacturers satisfy market demand by replacing R-410A to support F-gas phasedown without compromising capacity or efficiency both in heating and cooling operations.” Solstice^® L41y features a discharge temperature lower than R-32 and similar to R-410A, which means that discharge temperature mitigation is not required. It also has the same service pressure as R-410A, which negates system design changes in piping, brazing and vessels. Additionally, Solstice L41y enables up to 10 percent lower charge size compared to existing equipment that use R-410A. Its broader operation envelope enables the equipment to reach low-evaporating temperatures, hence outperform R-32 in heating mode and reach higher water temperatures in heat pump and chiller applications. Solstice L41y is the newest addition to Honeywell’s portfolio of solutions to help OEMs transition from high-GWP products to long-term, hydrofluoro-olefin (HFO) solutions that are currently available such as Solstice L40X, Solstice ze, and Solstice zd. Other solutions include the recently announced Solstice N41 (R-466A), a next-generation, non-flammable, reduced-GWP refrigerant that will meet the needs of direct air cooling applications requiring non-flammability such as VRF, roof-top and split air-conditioning units. Honeywell is a world leader in the development, manufacture and supply of refrigerants that are sold worldwide under the Solstice^® and Genetron^® brand names for a range of applications, including refrigeration, building and automobile air conditioning. Honeywell and its suppliers have completed a $900 million investment program in R&D and new capacity based on Honeywell’s HFO technology.
