HIGH RATE DISCHARGE SUPPRESSOR lEPn TECHNOLOGIES . HOERBIGER Safety Solutions PRODUCT INFORMATION SHEETDescription The IEP Technologies EHRD II is a high-rate discharge suppressor used for explosion suppression and isolation systems. Upon detection of an explosion event, the Explosion Protection Control Unit sends an actuation signal to the EHRD II valve mechanism. The valve opens extremely rapidly (less than 10ms), which allows the suppressant to be discharged through the nozzle system into the protected vessel to mitigate potential damage caused by the detected incipient explosion. The EHRD II is provided with a supervisory switch that continuously monitors the suppressor's pressure level when connected to an IEP Explosion Protection Control Unit. This suppressor also includes a pressure gauge for visual indication of the suppressor pressure. Features • Improved reliability due to continuous monitoring of pressure • Can be mounted on existing IEP flanges to potentially replace existing family of suppressors • Integrated pressure gauge to visually check pressure level Rated for dust and gas hazardous locations Transportation licenses: TPED (pi-marked) and CDG-TPE (rho-marked) approval allows suppressors to be pressurised in our factory, thus improving quality and eliminating the need to pressurise on site. ATEX and UKEX approved

lEPr TECHNOLOGIES HOERBIGER Safety Solutions Application The IEP Technologies EHRD II is designed to discharge suppressant in milliseconds within a process vessel or to mitigate the propagation of flame through interconnected ductwork. It is used in conjunction with IEP Technologies' range of control panels and detectors. IEP Technologies' sophisticated computer modeling techniques determine the expected reduced explosion pressure (Pred) and the quantity and size of suppressors to be employed.
