Industrial Equipment

OEM replacement & custom components

Knoxville's industrial equipment sector benefits from TVA's extensive power infrastructure and the region's manufacturing base. TVA's Bull Run and Kingston power plants require turbines, pumps, valves, and heat exchangers. Y-12 National Security Complex in Oak Ridge machines precision components with applications in industrial valve and flow-control equipment. Denso Manufacturing in Maryville requires hydraulic systems and material-handling equipment, and Knoxville's growing food processing sector — including Bush Brothers and Mayfield Dairy — adds demand for sanitary pumps, conveyors, and packaging machinery.
