HONEYWELL AND MULTISTACK BOOST SUSTAINABLE COOLING AND HEATING IN COMMERCIAL BUILDINGS

Honeywell announced that global commercial chiller company Multistack will utilize Honeywell’s next-generation refrigerant, Solstice^® 454B in its chillers and heat pumps for commercial building applications.

This partnership comes after a decade-long collaboration between the companies on research and development of hydrofluoroolefin (HFO) refrigerants, supporting the industry-wide commitment to eliminating fossil fuels in buildings through the adoption of energy-efficient alternatives.

“Since Solstice^® 454B offers a very close performance match compared to R410A, manufacturers can benefit from an easier and faster re-design process of their existing cooling systems - making it the best choice for customers seeking low-GWP refrigerant alternatives to R410A,” said John Keating, vice president and general manager, Stationary Refrigerants, Honeywell. “By working with leading cooling and heating equipment manufacturers such as Multistack, we enable our customers to meet their sustainability targets, contributing to a more sustainable and eco-conscious approach in the HVAC industry.”




As legislation to phase-out high‐GWP refrigerants escalates, it drives the need for efficient refrigerant alternatives to support the industry’s transition to low-GWP refrigerants. Starting in 2024, the United States Environmental Protection Agency (EPA) issued a final rule that cuts the production of high-GWP hydrofluorocarbon (HFC) refrigerants by 40%, underscoring the urgency for manufacturers to identify alternative solutions to tackle climate change.
