Unequaled Trust

Heyl Patterson Thermal Processing was created to provide reliable, custom-engineered, energy-efficient solutions for your drying, cooling, or calcining needs. Originally founded in 1874 as the Edwin Renneburg & Sons Co. of Baltimore, and later the Renneburg Division of Heyl & Patterson, the new Heyl Patterson Thermal Processing is a wholly owned subsidiary of CPEG. The name has changed a bit, but the same team of experienced engineers and craftsmen continue to produce innovative thermal processing equipment handling powders and bulk solids in the chemical, minerals, food, catalyst, metals, and biomass industries.
