Simply install the unit on the ventilation duct that connects to the underground, and it will automatically open and close the gate using the power of water, preventing flooding in the underground space.
VSS from FloodBreak, a company for which we are the agent. It utilizes the power of water during floods to automatically close the panels within the unit. There are no mechanical or electrical mechanisms, so no personnel or power are needed to close the gate. This is a unique and groundbreaking system that avoids human risk during installation and automatically deploys even when lifelines are lost. Once the water recedes, it automatically returns to the open position, ensuring that ventilation functions are not compromised during normal conditions.

Applications/Examples of results
To prevent water from flowing into underground spaces, using only water stop boards is insufficient. By incorporating custom-made VSS units into the above-ground ventilation sections connected to the underground, we can maintain ventilation functionality during normal conditions while shutting down the flow of water from above ground to below ground. - Ideal for preventing flooding in subways, underground roads, underground passages, and various underground facilities.
Detailed information
-
1) Water flows into the VSS. There are two panels installed at the top and bottom inside the VSS (the number of panels may change depending on the installation site conditions). 2) The lower gate automatically moves to the "closed" position due to the incoming water. 3) As more water flows in and the water level rises, the upper gate automatically moves to the "closed" position. - The ventilation openings become completely watertight, preventing water from flowing into the underground. - When the water level decreases, the panels automatically return to the "open" position.
