Galvanizing Furnaces

The Protherm high velocity system

Bespoke design and manufacturing

Our furnaces are meticulously designed and manufactured to your unique needs and requirements, with over one-hundred of our furnaces in use today. Extensive use of technologies such as computer-aided design (CAD) allow us to optimise the design, such as the size of firing lanes and burner positions.

Completed furnaces are usually shipped complete with thermal insulation, burners, combustion controls, and pipework - ready for immediate installation. Furnaces for kettles up to 12.5M in length have been shipped complete with the kettle as a single unit weighing over 50 tonnes.
