Thermo-processing Industry: High-performance air handling for extreme heat
In the thermo-processing industry, especially in industrial furnace construction and the heat treatment of metals, glass, or composite materials, process air is responsible for heat transport and maintaining the atmosphere. Fans and dampers often have to operate in close proximity to the combustion chamber. Quality Made in Germany provides the necessary technological reliability to permanently master these extreme thermal stresses.
Challenges and risks under massive heat load
The biggest challenge in the thermo-processing industry is material fatigue caused by extreme heat and frequent temperature changes. Components are often exposed to temperatures exceeding 800 °C, which places the highest demands on shaft sealing and bearing cooling. A failure of the circulation fans leads to uneven heating of the material, resulting in rejects due to structural changes or warping. Unplanned downtimes in thermo-processing technology often lead to days of downtime, as the furnaces can only be cooled down and reheated slowly and in a controlled manner.
Solutions and retrofit expertise: Durability under extreme conditions
Siempelkamp Industrial Fans manufactures specialized high-temperature fans for these extreme ranges, featuring water-cooled shafts and thermally decoupled motor pedestals. Our industrial dampers and slide gates made of high-temperature-resistant special alloys withstand loads of up to 1,200 °C and ensure gas-tight shut-off. To prevent energy losses, we integrate customized insulation systems directly into the components.
In the field of retrofitting, we support furnace manufacturers and operators in extending the service life of thermally stressed components. We modernize existing plants, independent of the manufacturer, by using heat-resistant impellers and optimizing sealing systems to minimize heat loss. Using FEM structural analyses, we ensure that the components can permanently withstand mechanical stresses even at maximum heat. Our full service ensures the operational safety of complex furnace systems worldwide.
