New passive, Pop-Up Spill Barriers from DENIOS automatically engage at the first flow of liquids, protecting against catastrophic spills and sprinkler releases.

Installed in doorways, these unique designs can limit the spill or sprinkler release to a single room within the facility, reducing the cost for cleanup or facility damage. Pop-Up Spill Barriers are fully automatic and require no external power source or compressed air supply.

Flexible design allows installation on inside or outside of exterior doors, with widths available up to 16-feet. Constructed of solid welded stainless steel for chemical resistance and long service life. This self-contained one-piece design is factory adjusted and lubricated, and easily installs in existing doorways. Built in Louisville, Ky., and proven in thousands of installations worldwide, DENIOS Pop-Up Spill Barriers are ideal for use anywhere that sprinkler release or spill containment is desired.

How it works

When not deployed, the Pop-Up Barrier stores flat in the floor, so there is no need for berms or ramps, and allows for normal vehicular traffic of up to 6.5 tons axle weight to pass. It automatically “pops up” when liquid enters the built-in collection sump creating a liquid tight seal which prevents the liquid from entering the doorway. There is no power, air supply, or external sensor required, nor is any human interaction needed. It provides instantaneous, automatic protection against spills and sprinkler releases. After the event, Pop- Up Barriers can be reset and reused.

Barriers are built specifically for the doorways they protect, with sizes from 3-feet to 16-feet wide and heights of 12-iches, 18-inches or 24-inches tall (16’ x 24” not available). A video demonstration of this technology can be seen here:
