Fluid viscous dampers are highly effective at dissipating seismic energy, and do not alter the stiffness of the structure. They can also be used to dampen vibrations caused by other factors, including wind, heat and traffic.
This product is in compliance with the following standards:
- "Dampers for vibration energy dissipation of buildings" JG/T 209-2012
- "Fluid viscous damper and lock-up device for railway bridges" TB/T 3561-2020
