The BS&B Type IPD Explosion Suppression System provides protection of process enclosures where dust suspended in air represents an explosion hazard. The early stages of the pressure rise associated with a dust explosion are detected by the Unitized Sensor which is mounted to the equipment to be protected.

When at least two of three individual pressure sensors within the Unitized Sensor respond, an electrical signal activates the Explosion Suppression Cannon(s) installed on the equipment causing the pulverized suppression agent (food compatible sodium bicarbonate) to be energized & discharged from the front of the Cannon into the equipment. This extinguishes the early stages of combustion of the process material before it builds into a deflagration which can generate a pressure spike exceeding the strength of the process equipment.
