VENTILATION AND CONTROL DAMPER
S
tructures such as tunnels, subways, mines, technical tunnels, transport systems and ships, but also complex processes in industrial plants face the challenge of specifically controlling the air or exhaust air.
The technical possibilities shows our experience
Temperatures from sub-zero to 1000C° plus
Pressure up to 40,000 Pa
Possible from very small dimensions to dimensions over 10 x 10 m

Civil engineering damper
Tunnels, subways, mines and technical tunnels have manually or automatically operated damper systems to regulate and ensure air exchange.
We are the market leader in specially developed and tested tunnel fire dampers, which secure the escape route and limit the fire in the event of a fire.

Industrial damper
Industrial dampers are systems used in industrial process control and regulation for a wide variety of media such as exhaust gases.
They serve to regulate the media and are used in the food industry as well.
