[Birmingham, UK – Feb 2026] – Grayson Thermal Systems has reached a major production milestone on one of its longest-running programmes with Dennis Eagle, delivering the 10,000th engine cooling pack for the manufacturer’s Elite Euro 6-compliant refuse collection vehicle (RCV) platforms.
The milestone highlights a partnership spanning more than 20 years, during which Grayson has consistently supported Dennis Eagle across multiple vehicle platforms. The Birmingham heating and cooling specialist began supplying its coolers for the Elite 2 Euro 5 in 2005, continuing through to the Euro 6-compliant Elite 6, launched in 2014, and its Elite+, launched in 2022.
Developed to meet stringent Euro 6 emissions standards and enhance driver safety through a low-entry, direct-vision cab, the Elite 6 and Elite+ platforms are powered by the Volvo Penta MDE8 280HP and 320HP diesel engines. Grayson was re-selected in 2012 to design and manufacture a bespoke, compact under-cab cooling module capable of maintaining thermal stability under the demanding stop–start conditions typical of urban waste collection operations.
Building on its proven experience from the Elite 2 project, Grayson engineered the new system to deliver reliable thermal performance within challenging packaging and airflow constraints. Since entering production, the Grayson-designed cooler has demonstrated exceptional reliability and durability, supporting municipal and commercial fleets worldwide.
Commenting on the milestone, Stuart Hateley, Managing Director at Grayson, said: “Reaching 10,000 units supplied to Dennis Eagle is a proud moment for everyone at Grayson. It reflects not just the success of a single product, but the strength of a partnership built on trust, consistency and shared standards of quality.
“Dennis Eagle is recognised as one of the most respected names in the refuse vehicle sector, and we’re proud to have supported them over the past 20 years as a dependable and responsive supplier. For us, reliability goes beyond product performance: it’s about being there for our customers, adapting to their evolving needs, and continually earning their confidence through engineering excellence.”
Chris Benton, Head of Purchasing and Supply Chain at Dennis Eagle, said: “Grayson has consistently delivered high-quality cooling solutions that meet the rigorous demands of our refuse collection vehicles, helping to ensure our customers’ fleets operate efficiently and safely. Grayson’s thermal management expertise and its team’s commitment to outstanding engineering, quality and reliability have made it a valued supplier. Achieving the 10,000-unit milestone and sustaining a partnership for over two decades underscores the strength and excellence of this collaboration.”
The milestone underlines Grayson’s ongoing role as a trusted international supplier of engineered cooling systems to OEMs. The company continues to collaborate with Dennis Eagle on future vehicle platforms while supporting other leading manufacturers across the commercial, special and off-highway vehicle sectors.
Over its two-decade partnership with Dennis Eagle, Grayson has also supplied systems for vehicles operating as far afield as Australia and New Zealand, demonstrating the company’s ability to deliver dependable thermal management solutions on a global scale.
