SHERIDAN, WYOMING – July 13, 2025 – Boaters looking to reduce their carbon footprint without sacrificing onboard comfort have reason to celebrate as Dometic unveils its 2025 marine air conditioning systems, featuring next-generation refrigerants with dramatically lower global warming potential (GWP).
These cutting-edge AC systems mark a major step forward in sustainable marine technology. Dometic’s new refrigerants are designed to comply with upcoming global environmental regulations while ensuring the same premium performance and comfort that customers expect from the brand.
Introducing R-454B and R-32 Refrigerant Technologies
At the heart of Dometic’s 2025 lineup are two new refrigerants engineered for lower emissions and higher efficiency:
- R-454B Refrigerant: "The R-454B gas delivers a 78% reduction in GWP compared to the commonly used F-Gas R-410A, making it an excellent choice for a wide range of marine air conditioning applications."
- R-32 Refrigerant: "For specific A/C applications, Dometic is transitioning to R-32 technology, which offers a 68% reduction in GWP versus R-410A. This transition contributes to reducing the overall environmental footprint of its systems while maintaining high cooling efficiency."
This refrigerant shift reflects Dometic’s broader goal to lead the marine climate technology space with innovations that protect the planet.
Revolutionizing Marine Climate Control Systems
To support these new refrigerants, Dometic has upgraded its marine climate control systems with advanced engineering enhancements. These improvements ensure that boaters continue to experience exceptional cooling performance — now with less environmental impact.
"These moves clearly demonstrate a company-wide commitment to build and support the best solutions for the industry while meeting global sustainability goals. Towards this end, Dometic will continue to work closely with organizations such as NMMA and ABYC to develop safe, sustainable solutions,” said Eric Fetchko, Dometic Marine Segment President.
A Commitment to Sustainability
The new refrigerants aren’t just a compliance move — they’re part of a larger vision.
"The use of low GWP refrigerant coupled with our high-performance, variable capacity systems will make Dometic climate solutions one of the most energy-efficient and low-emissions products on the market. This demonstrates that we are always looking for ways to make things better for our OEM customers, boaters, and the planet.” added Fetchko.
Dometic’s marine systems — used on boats ranging from 20 feet to superyachts — are designed, developed, tested, and built at state-of-the-art facilities in Pompano, Florida, and Milan, Italy. Each unit is engineered with quality, performance, and sustainability in mind.
Future-Proofing Marine Technology
As climate-focused regulations continue to evolve, Dometic is preparing the industry for a more sustainable future. Its 2025 air conditioning systems are aligned with global efforts to phase out high-GWP refrigerants — keeping boaters compliant, efficient, and eco-conscious.
