The dampers can be provided with a pneumatic, hydraulic or electric actuation system that will move the blades between 0-100% exhaust gas flow controls.
The blades are fitted with flexible seals that are forced on to landing bars which provide a high sealing efficiency on flow.
A sealing air skid comprising of duty/standby fans complete with pressure switches and non-return valves can be provided to ensure 100% sealing of the duty damper to eliminate any exhaust gas leakage to the heat exchanger.
- Flexible: The size, number and shape of the blades can be modified to fit most applications.
- Fast reaction time: Minimal time for the damper to travel from fully open to fully closed.
- Lower power consumption: Actuation system power requirements are low
- Fail Safe: An air reservoir can be fitted to ensure that there is always sufficient air available to drive the dampers to the fail-safe position.
