    Active Dry Chemical Suppression

    Chemical Suppression

    The most universal solution for explosion mitigation, chemical suppression systems are the most flexible choice since they can be used on nearly every application.
    Whether a vessel is located indoors or outdoors, chemical suppression provides a contained solution for explosion mitigation.
    CV Technology’s Interceptor®-HRD suppression system is the most advanced in the world with High Rate Discharge bottles, cutting edge detectors, and intuitive controls.


    The Interceptor®-HRD™ chemical suppression system is designed to provide an active method to protect process system equipment from a dust explosion hazard. The fundamental operation of the Interceptor®-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 controller, pressure or optical detectors, and the high rate discharge (HRD) bottles. As a deflagration develops, the pressure inside the vessel will begin to build rapidly. The DetEx 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.


    Chemical suppression equipment can be used on a variety of process equipment including as isolation for ductwork. Suppression systems are ideal for pneumatic conveying equipment, dust collectors, bins, cyclones, bucket elevator, mills, silos, fluid bed dryers, spray dryers, and pipes.
