Product Overview

Damptech manufactures seismic and wind damping devices centred on the rotational friction damper, offered alongside V-dampers, rhombus dampers, multilevel dampers, and friction bearings. Damper capacities range from about 20 to 5000 kN.

The products protect buildings, bridges, elevated highways, towers, offshore structures, and industrial facilities. Devices are configured as single units or multi-unit assemblies with two to eight joints, and the company manufactures its dampers in-house.

Market Outlook

Demand for seismic protection continues to broaden as infrastructure owners adopt damping systems for new construction and retrofit projects. Damptech's installed references span Japan, Greece, Turkey, the United States, China, Chile, Qatar, India, Italy, Denmark, South Korea, and Hungary, showing adoption across seismic regions on several continents.

The company sells internationally through partners and distributors rather than depending on a single regional market. Its device families cover capacities from about 20 to 5000 kN, positioning the line for applications from light industrial structures to large bridges and towers.

Competitive Advantages

Damptech's rotational friction dampers are adjustable in place after installation, allowing their force threshold to be tuned on site without removal. The devices contain no fluids, so they require no maintenance and avoid the leakage concerns associated with viscous dampers.

The friction design remains stable under repeated load events, which suits structures exposed to aftershocks or multiple seismic cycles. Competing solutions on the market rely on viscous fluid, buckling-restrained brace, or base isolation mechanisms supplied by firms such as Taylor Devices, GERB, mageba, and CoreBrace.
