Fluid Viscous Dampers

ASHUN Fluid Viscous Dampers (FVDs) are top-tier seismic energy dissipation components. By converting the kinetic energy of earthquakes and high winds into thermal energy via precision-engineered orifices, they significantly reduce structural displacement. As Taiwan's only manufacturer with end-to-end capabilities from design to TAF-certified laboratory issuance, all our products undergo rigorous physical testing on a national-grade MTS platform, establishing world-class safety assurances for critical structures.

Core Operating Principle & High-Efficiency Energy Dissipation

Utilizing fluid dynamics, the piston forces high-viscosity silicone fluid through precisely calculated orifices, converting seismic kinetic energy into thermal energy.

Extreme Condition Stability & Advanced Sealing Technology

Filled with customized high-viscosity silicone fluid and an exclusive high-end sealing system, featuring excellent shear resistance to ensure reliable damping under continuous actuation.

Reducing Structural Loads & Optimizing Engineering Value

Efficiently absorbs massive seismic energy, significantly reducing inter-story drift and floor acceleration to optimize overall building protection configurations.

Collaborative Engineering Design & Customized Applications

Working closely with structural engineers to precisely design customized specifications based on project-specific damping coefficients and velocity exponents.

The First and Only in Taiwan: End-to-End Design, Manufacturing, and TAF Certification

Taiwan's only major damper manufacturer integrating design, manufacturing, and certification, operating our own TAF-accredited laboratory for authoritative quality endorsement.
