Protect important equipment and areas from flooding with top-class water resistance performance.
The "Handle Tight Waterproof Door," which can handle water heights of up to 30 meters, and the "Self Tight Waterproof Door 3," which does not require tightening operations, are equipped with special mechanisms such as dual-axis hinges that utilize water pressure to ensure the door is tightly sealed. The leakage amount is only 0.001 cubic meters per hour per square meter of door area, demonstrating top-class flood prevention performance equivalent to JIS Ws-6 and JSTM HWL-5 standards. By keeping the leakage amount low even during prolonged flooding, the risk of damage can be reduced.
