Dynamic vibration damper

Dynamic vibration damper The dynamic vibration damper is specially designed by BEIRENS and installed in the head of the stack to absorb vibrations and consequently mechanical stress applied to the stack.

can particularly originate in the airflows around the stack (Karman vortex street), but also earthquakes and, in certain cases, pulsing sources of extraction linked to the stack (fan, turbine).

The dynamic vibration damper is a pendular ring made up of a mass-spring system that dissipates mechanical energy transmitted to the stack. It is compatible with Single-flue, Double-wall, Multi-flue and Gigogne chimneys.

• Performance, reliability, durability
• Stability at all heights
• Optimisation of pressure losses
• Easy to deploy
• Easy to inspect and maintain
• Wide range of fi nishes according to the stacks
