Viscous dampers (also known as seismic dampers) are hydraulic devices that dissipate the kinetic energy of seismic events and cushion the impact between structures. They are versatile devices that can be designed to allow free movement as well as controlled damping of structures to protect them from wind load, thermal motion, or seismic events.

Seismic Dampers, Viscous Dampers, fluid viscous dampers
Our seismic dampers are well-suited for large displacement and/or large load applications such a bridges, buildings, and other large structures. Available in ratings up to 1,000 KIP.
