IPD, the system for suppressing and isolating dust explosions from BS&B Safety Systems, detects critical rises in pressure to the millibar and reacts at lightning speed. The highly effective extinguishing agent smothers any flame in an accumulating explosion in a fraction of a second, long before the explosive pressure is unleashed. When used for isolation, the IPD system stops the explosion spreading to connected parts of the facility. To make sure the IPD system is ready for use again quickly after being triggered, the designers developed a modular design that allows for immediate resetting on site.
The extinguishing unit consists of an unpressurised, easily replaceable extinguishing agent cartridge and a pressurised container that is filled with nitrogen during installation or reset. The lack of a pyrotechnic trigger means that none of the individual components or the completed system are classified as hazardous goods. This makes both handling and management much easier. Furthermore, the extinguishing unit requires no extra discharge nozzle for the agent. Instead, the integrated rupture disc becomes an aerodynamic outlet when activated. The design avoids the use of plumbing that can become blocked.
