Experience with Every Type of Heat Processing Equipment

Since 1946, F.S. Sperry has been extensively involved in the engineering, design and construction of most types of heat processing equipment. We’re contractors and engineers, and we love our work.

Over that time, we’ve built a tremendous knowledge base about refractories and manufacturing equipment. Some of this equipment has been out of production for decades – but is still being used in plants – and we might be the only ones left who understand it.

Check out our experience by equipment type below, or visit our Resource Center to learn more about the volume of blueprints and schematics we have in our possession.
