HIGH RATE DISCHARGE


EXPLOSION SUPPRESSION IN THE BLINK OF AN EYE


Dry chemical suppression systems are an advanced method to secure every type of industry from the danger of explosions. Extinguishing medium, usually sodium bicarbonate, offers safe solutions in industries such as food or pharmaceuticals, requiring higher hygienic standards. The HRD System is a certified active explosion suppression system.

The HRD Explosion Suppression System is designed to provide an active method to protect process system equipment from a dust explosion hazard. The principle of operation for the HRD system is detection of the pressure rise during the initial stage of an explosion, followed by fast injection and homogeneous distribution of an extinguishing agent into the protected vessel. The chemical suppression system consists of a control unit, pressure or optical detectors, and the high rate discharge (HRD) bottles.

HRD SYSTEM COMPONENTS


As a deflagration develops, the pressure inside the vessel will begin to build rapidly. The DetEx Explosion Pressure Detector will detect the rate of pressure rise over a certain time period and activate the High Rate Discharge bottles. Once activated, the HRD bottles will disperse suppressant into the protected vessel inhibiting the explosion from further developing, thus reducing the pressure and preventing any vessel breach.
