What Econotherm (UK) Ltd does

Econotherm (UK) Ltd is a Bridgend, Wales-based manufacturer that designs and produces heat pipe heat exchangers for industrial waste heat recovery, founded in 2007 and operating with 16 employees. Its core technology is a patented heat pipe manufacturing process deployed at its Wales production facility, with products spanning Counter-Flow, Through-Flow, and Cross-Flow configurations in Gas-to-Air, Gas-to-Steam, Gas-to-Water, Gas-to-Thermal Oil, Steam Condenser, and Steam-to-Air variants. Solutions are custom-built and range from a few kilowatts to several megawatts, with the Through-Flow design rated for exhaust temperatures up to 1000°C, targeting difficult-to-recover heat such as hot and/or dirty exhaust streams.

The company sells into enterprise industrial customers across petrochemical, oil & gas, steel, food processing, power generation, defense, and automotive sectors, with a documented installed base of 300+ units across more than 350 production units in operation globally. Distribution is global through 15 distributors and installation partners delivering turnkey solutions, plus direct enterprise sales supported by engineering consultation; marketing is primarily via case studies, technical blog content, and joint webinars with parent company Solex Thermal Science. Econotherm was acquired by Solex Thermal Science, a Canadian thermal energy and bulk materials specialist, in July 2023 and now operates as a subsidiary within that group, continuing to land contracts internationally (e.g., Rotterdam refinery January 2026, Thai refinery March 2026) and to pursue development projects funded under EU Horizon 2020 and Innovate UK programs.
