Furnace controllers are used to control temperature, heat delivery, and other variables in industrial furnaces. They control the burner flame, air mixture and trim to maintain and optimize furnace performance.
Industrial furnaces are built of several kinds of high temperature (refractory) materials to hold the process material and hold in the heat without breaking down during the several months that they usually run.
Vacuum chambers and components are specialized vessels that can maintain a high vacuum process environment for manufacturing thin films, microelectronics, optics and materials.
