Automatic doorway spillbarrier FM approved

High temperature resistant, according to Hydrocarbon curve over 30 minutes up to 1000 °C tested barrier, to retaining burning and non-burning, solid and liquid substances. Automatically and without external energy closing and secure sealing barrier – consists of a perpendicularly standing metal barrier body with revolute joint and a barrier box on one side and a U-profile with impulse tensioner on the other side. The metal barrier is held at its vertical rest position by an electrical magnet.

When the standard liquid probe is triggered, or the close button is pressed, or there is a power blackout, or any other alarm signals of the central alarm system are active, then the closing process starts. The closing process is fully automatical and without any external energy. From the vertical position of rest, the barrier rotates vertically and slowly to the horizontal closing position at the bottom into the U-profile. In the lower horizontal closed position arrived, the metal barrier is automatically locked by an impulse tensioner. The unlocking of the tensioner is to do manually and the opening of the barrier is done by hand via chain or hand wheel.

FM class number 4985 produced, tested and approved barrier. Type tested through FM Approvals. Type tested through MPA Dresden. Delivered and installed ready to use by us as professionals to WHG for light and highly flammable substances and water-polluting / non-combustible substances. However plus customs, travel costs, freight and packaging.
