Article covers company's expertise in waste heat recovery from furnace streams

 

BRIDGEND, Wales, October 9, 2025 – Econotherm (UK) Ltd. is featured on the cover of the Foundry Management & Technology Magazine's October issue.

​​

The article addresses the issues that metalcasters and other manufacturers that operate melting processes are facing beyond traditional production challenges — issues such as decarbonization, safety and global competition.

​​

Of note, the Foundry article focuses on energy efficiency, a highly engaged topic of discussion given that melting primary or secondary metal alloys is estimated to contribute more than two-thirds of total energy use and greenhouse gas emissions in many operations.

​​

Concerning Econotherm, author Scott Harris highlights innovations that are taking place in furnace design and opportunities surrounding waste heat recovery and reuse. He points to heat pipe gas-to-air pre-heaters, such as the ones developed by Econotherm, as a proven technology for capturing exhaust energy.

​

The article highlights two Econotherm collaborations:

​

• Aisin Automotive Castings: Three gas-fired aluminum furnaces were eequipped with a heat pipe heat exchange system that were designed to recover 500 kW of waste heat from the flue-gas stream to pre-heat combustion air, reducing fuel consumption by 15%.​

​

• U.S. wire manufacturer: An Econotherm heat exchanger was installed on a copper melting furnace, recovering 6.56 MMBtu/hr (1,921 kW) of waste heat, and reducing fuel consumption by up to 20%.
