Utility Trailers: Delivering for the Planet

Even before they hit the road, Utility Trailer reefers are making a positive impact on the environment. For Utility, enhanced performance and energy efficiency are top priorities. That’s why when they needed a more energy-efficient foam insulation for their trailer, Utility chose Honeywell’s Solstice® Blowing Agents with ultra-low global warming potential (GWP).

The reefer industry faced an environmental challenge due to the utilization of high global warming potential (GWP) materials, including hydrofluorocarbons (HFCs), in the production of insulation foam. Although HFCs were the favored blowing agent for polyurethane foam insulation applications for years, their use contributes to greenhouse gas emissions. Consequently, HFCs are now undergoing phased-out measures. The industry looked for an alternative that minimized global warming potential (GWP) while maximizing energy efficiency. Additionally, Utility needed a solution that delivered superior insulation performance.

“Our 3000R reefers are fully insulated with a 360° void-free, foam-in-place insulation. We needed a non-HFC, ultra-low GWP blowing agent for our foam insulation that can improve thermal efficiency and is good for the environment. Solstice met those requirements,” said Steve Bennett, Utility President & COO.
In addition to refrigerated trailers, Solstice is used in the side wall’s polyurethane foam core of Utility’s 4000D-X Composite series of dry vans, as well as Cargobull North Americas line of TRUs. The 625 Hybrid and 655MT Hybrid TRUs use a Solstice-based R-452A for their refrigerant, replacing 404a and reducing greenhouse gas emissions.

“We value our sustainability practices and goals. Since converting to Solstice, we know that our ongoing efforts are having a substantial effect in reducing carbon dioxide levels,” added Steve Bennett.
