Caltherm, a globally recognised manufacturer of industrial ovens, dryers, and furnaces, has been named a finalist in the Small Business of the Year category at the 2025 Staffordshire Chambers of Commerce Business Awards. Sponsored by Sempar, this prestigious award honours outstanding businesses with fewer than 50 employees, with judging criteria focused on leadership, innovation, environmental impact, staff development, and long-term business sustainability.
With over 46 years of continuous operation from its Chesterton site, Caltherm has become a trusted name in British engineering, serving blue-chip clients across the Aerospace, Automotive, Pharmaceutical, Composite, Heat Treatment, and Defence sectors. Its global customer base includes industry giants such as Rolls-Royce, BAE Systems, Bombardier, RNLI, Ryanair, and Federal Mogul, with projects delivered across the UK, China, USA, Mexico, Italy, Singapore, and beyond.
Despite global competition, Caltherm remains firmly committed to British manufacturing. The company has grown its workforce and turnover year after year while continuing to support local employment and industry skills development. Many team members have been with Caltherm for decades, and the company’s active apprenticeship programme ensures that essential engineering knowledge is passed on to the next generation.
As it looks to the future, Caltherm continues to combine the personal touch of a family business with the global reach and capability of a market leader.
