We are specialize in the design and construction of multiple and biplane dampers for refineries, cement plants, air-smoke ducts of conventional boilers, limited flow turbogas exhaust ducts and for the interception, regulation and bypass of plant components.
The type and size of the dampers depend on the specific functional requirements, sealing, temperature, pressure and flow, as well as the variety of the fluid.
With a seal rating of up to 99.9%, our multiple dampers are suitable for regulation and can be operated by pneumatic, electric or manual actuators. They have wing blades and opposing blade movement.
The biplane dampers on the other hand, have double-sheet blades and opposing blade movements. They are suitable for gas interception with a perfect seal: 100% with pressurization air and up to 99.9% without pressurization air.
