Refractory Lined Dampers

Our preferred design for very high temperature dampers is one where the entire damper (body, vane and spindle) are manufactured from high temperature grades of steel (e.g. 253MA, SS310). We manufacture dampers of this design to work up to 950⁰C. However, we can also offer internally refractory-lined dampers with carbon steel bodies, where only the vane and spindle need to be made from high temperature grades of steel. This design is best suited to ductwork which itself is refractory lined.
