SIEMPELKAMP Industrial Dampers & Slide Gates
Controlling and shutting off gas flows under extreme thermal and mechanical loads requires the highest level of engineering precision. As a premium manufacturer, Siempelkamp Industrial Fans produces tailor-made industrial dampers and slide gates that set standards worldwide in heavy industry, thermal processing technology, and environmental technology. With an operating range from -100 °C to +1,200 °C, these components offer maximum safety and reliability in Quality Made in Germany.
Every industrial damper is individually designed according to the specific requirements and process parameters of the customers. Whether for precise volume flow control or absolutely tight shut-off – the design is based on decades of experience and the use of state-of-the-art manufacturing processes. The flexibility in dimensioning allows for the realization of round designs up to a diameter of 4,500 mm as well as rectangular versions up to dimensions of 3,000 x 8,000 mm.
The technological diversity is reflected in the different designs, which offer the optimal solution for almost every industrial scenario. The portfolio includes, among others:
- Butterfly Dampers & Shut-off Dampers: For reliable regulation and separation of media flows.
- Multi-leaf Dampers: Ideal for large cross-sections and demanding control tasks.
- Guillotine Dampers & Slide Gates: For space-saving, high-tightness shut-off in ducting systems.
- Inlet Vane Controls: For flow-optimized volume flow control directly upstream of fans.
- Diverter and Directional Dampers (e.g., 3-way bypass dampers): For efficient distribution or redirection of gas flows.
- Non-return Dampers & Double Pendulum Flaps: For automated control of flow directions and material streams.
- Special Solutions: Such as tandem dampers, double shut-off dampers for sealing air systems, and high-efficiency slide gate designs.

A special focus is placed on tightness and durability. Depending on the requirement, metallic, metallic-flexible, or soft-sealing blade seals are used. Complemented by various shaft seals and gas-tight/pressure-resistant designs up to 10 bar, the components can withstand even aggressive or heavily dust-laden media. Control is achieved via diverse drive types that ensure exact positioning. This includes electric drives, pneumatic solutions (such as rotary lobe drives or piston rod cylinders), as well as manual versions using manual adjustment with a scale, worm gears, or lockable manual levers.
