Explosion Vents

IEP-BRILEX Explosion Vents (now owned by IEP Technologies – Hoerbiger Safety Solutions) combine safety and shorter opening times. The lightweight and simple construction guarantees a quick and safe opening of the disc. Most IEP-Brilex designs have 100% venting efficiency (contact us for specific details). The higher service life enables their use under the hardest conditions. This can be as high as a “sixty-fold” benefit compared to traditional triple-section designs that are now “out-of-date”.

Explosion Relief Venting

Explosion Venting

Venting of dust explosions has been practiced for more than 50 years and provides the best protection for facilities where dust explosions can occur. When specifying explosion vents, the immense impact of pressure waves and flame propagation in the outside area needs to be considered. Explosion relief must therefore be directed to a safe area. The flame width and length can be calculated with EN14491:2012. If the area cannot be made safe, then our flameless vent designs should be considered. This could be our Hoerbiger EVN series or our IV8 series.

IEP-Brilex Type KE – Flat Single Section Explosion Vent

If the negative pressure is not greater than 50% of the rated rupture pressure and the pressure cycling is not severe, installation of a domed vent has no extra benefit. For this application, the IEP-Brilex KE is an alternative to the domed GE. The IEP-BRILEX – KE provides long durability and aerodynamic advantages compared to the domed type, for example in cyclones. Pressure spike control, cross rib stiffening, folded edges, and laser cut slits in the flange area are standard KE design features. Type KE can also be manufactured/rolled in a curved configuration to match the diameter of the vessel. Venting efficiencies are generally 100% throughout the size range and available with values of Pstat down to 0.02 bar.

By using IEP-BRILEX Explosion Vents in combination with a unique IEP-BRILEX Ceramic Filter, economical venting of dust explosions is possible. When the vent opens during an explosion, the ceramic filter retains the dust and cools down the hot gases.

Times have changed since explosion quenching systems had to be thrown into the waste bin after a single use. The IEP-BRILEX IndoorVent can be re-used after changing the filter cartridges and the explosion vent. A maintenance time of approximately 30 minutes is only needed before it can be used again. IEP-BRILEX guarantees this after each dust explosion.
