Custom air heater seal information

Air Heater Seals

Valmet manufactures a complete range of hot and cold end radial, circumferential, bypass, axial, and post sealing assemblies including holding strips and hardware. Our technical library contains the dimensions and specifications for the majority of air heater seals. Periodically, a template or sketch of the seal segment requested is required to ensure exact duplication of the component.

Air heater seals greatly reduce regenerative leakage, improving heat rate, reducing fan operating cost and reducing gas volume to your pollution control equipment.

Valmet fabricates exact replacement-in-kind seal assemblies.

As circumstances and individual customer applications indicate, we will recommend alternate gauge and/or material specifications to reduce leakage, enhance reliability and longevity. We manufacture in Corten, or any grade of stainless steel, including 304, 309, 310, and 316.
