HDB Explosion Suppressors

HDB Explosion Suppressors

HDB explosion dampers are used in ventilation systems to prevent the explosion wave from entering the building through exterior walls. They are designed with high ventilation capacity. The dampers can protect people and equipment from explosions or sudden pressure changes (such as those caused by hurricanes, etc.). When an explosion occurs, the damper closes instantly due to the shock wave; once the shock wave subsides, the damper automatically returns to its original position. They are used in major refineries, oil and gas facilities, nuclear power plants, and other facilities where there is a risk of explosion. They are installed at the air intake and exhaust points of these facilities.
