New fire damper

We created a new fire damper which was tested for seismic and fire proof protection especially for nuclear industry.

Construction of this fire damper allows to use big dimensions and to install in parts that means starting with a casing as a lost formwork and adding later all components.

See our leaflet and film showing installation advantages of this product.

We are able to certify this product according to your needs and expectations.

Fire proof time of 240 minutes could be easily certified as well as seismic calculation and resistance against shock wave load.
