HOERBIGER Safety Solutions Explosion Protection System Components Advantages: • Allows explosion relief venting to be applied in areas where flame ejection cannot be permitted • Proven design provides fast, reliable operation • Suitable for venting applications where use of a vent duct is not practical or feasible • Requires minimal maintenance Application IEP Technologies offers flameless vents for applications requiring indoor or outdoor explosion relief venting where flames cannot be directed to a safe location or where the use of a vent duct is not practical or feasible. Standard Flameless Vents Both the IndoorVent IV and the IndoorVent EXL are ATEX compliant flameless vents comprising of a bursting disc, a burst-sensor, a gasket, and a ceramic mesh vent filter to quench the flame. When an explosion occurs, the bursting disc ruptures once the pressure increase exceeds the burst disc rating. The fireball passes through the ceramic mesh vent filter where the flame is quenched, and cools the combustion gases as they pass through the filter. The integrated electronic burst indicator keeps plant personnel informed of the status of the system.

Spring-Loaded Flameless Vents The EVN 2.0 is an ATEX compliant round flameless vent comprising of a re-closeable, spring-loaded valve plate, a switch to detect the opening of the valve plate, a gasket, and a stainless steel flame arrestor. When an explosion occurs, the valve plate opens once the pressure increase exceeds the opening pressure. The fireball passes through the stainless steel flame arrestors, which quenches the flame and cools the combustion gases as they pass through them. The integrated switch keeps plant personnel informed of the status of the system. Ordering Information...
