IEP Technologies range of Industrial Explosion Protection solutions includes the Brilex and HOERBIGER range of venting solutions. Further details on the Brilex and HOERBIGER product range including standard and flameless vents is available in the specific venting sections below.

Asset 1

The Brilex range of high quality explosion venting solutions are manufactured at our plant in Brilon Germany using state of the art technology to ensure unparalleled quality and efficiency.

BRILEX and HOERBIGER venting solutions offer a range of certified protection devices to safeguard production processes from the destructive power of industrial explosions. The manufacture of these high performance life-safety systems requires production processes that comply both with international standards and directives and that meet the requirements set out by multiple quality-assurance systems.

Explosion Relief Venting

Venting of industrial dust explosions has been practiced for many decades and provides an economical protection solution for facilities where dust explosions can occur. When specifying explosion vents, the impact and associated risks of the ejected fireball (both pressure and flame) in the vicinity of the installed vent needs to be considered. Explosion relief must therefore be directed to a safe area. If explosion venting is a suitable option for an application then explosion isolation must also be considered in order to reduce the risk of flame propagation along ducting to connected process plant.


IEP Technologies complete range of Explosion Vents is specially designed for relief of industrial dust explosions protecting people and industry worldwide.

IEP Technologies explosion vent panels are designed to open at a predetermined pressure, to allow the fireball and explosive pressure to vent to a safe area. Vent panels are available in a full range of sizes, configurations and opening pressures. Depending on the specific application, explosion vent panels are available in flat, multi-layer and domed formats to provide the right protection solution. Suitable for a very wide range of explosion parameters ranging from very high KSt values down to very low pred levels, engineered and selected correctly explosion venting can serve as the simplest protection method. Whether the best venting option for a specific application is a standard or a flameless vent; explosion isolation must also be considered in order to reduce the risk of flame propagation to interconnected process vessels or the plant itself.

Standard & Flameless Venting Solutions

IEP Technologies provides the appropriate explosion vent for the application with a wide range of vents available. The venting protection options available include standard vents for applications where the fireball and associated pressure can be released into a safe area and flameless venting are possible solutions for those applications where flame ejection cannot be tolerated. Standard and Flameless Venting solutions are detailed below.

Explosion Vents

Explosion Vent - GE (rectangular and round)

Filter installations with pneumatic cleaning systems and high vacuum operations require an explosion vent that can withstand vacuum and positive pressure cycling for a long periods of time. For such requirements the GE style vent is the best choice. Its domed design enables negative pressure resistance without the need for an extra vacuum support. Standard GE features include pressure spike tolerance and integrated flange gaskets.

Explosion Vent - KE

If the negative pressure is not greater than 60% of the rated opening pressure, installation of a domed vent has no extra benefit. For this application the KE style vent is an alternative to the domed GE. The KE provides long durability and aerodynamic advantages compared to the domed type, for example in cyclones. Pressure spike tolerance, integrated flange gaskets, cross rib and folded edges are standard KE design features.

Explosion Vent - KER

The KER style vent is perfect for standard applications in powder handling and storage. The KER is suitable for plant equipment with static over/under pressure conditions up to 50% of the rated rupture pressure. A unique feature with the KER is that edge reinforcement in its design allows the KER to be mounted without an outlet flange thus reducing installation costs. Cross rib and folded edges are other standard KER design features.


Dust Explosion Venting solutions can be provided with a range of accessories from components which assist in installation to sensors which interface with controls devices Detail on the complete range of venting accessories can be viewed here.

Flameless Venting

The EVN Flameless Vent

The EVN range of flameless vents are designed to quench the ejected flamefront and relieve the pressure from a dust explosion. Offered in a range of styles each with an integrated flame arrester designed to provide flameless pressure relief. The revolutionary EVN range of flameless vents have a low-mass valve plate and low opening pressure. This flameless vent reacts within fractions of a second in the event of an explosion. Following an explosion, the valve plate closes and seals again, lowering the risk of post-explosion fires.

The IV8 Flameless Vent

The IV8 Flameless Explosion vent provides an explosion protection solution for process vessels which are located inside a building or areas where standard explosion venting cannot be safely employed. For these applications, flameless explosion vents may be the best protection solution. When an explosion occurs, the venting device opens and vents the explosion pressure and flame through a flame arrester, thereby cooling the hot gases and quenching the flame. The IV8 utilizes a stainless steel explosion relief vent and flame arresting mesh enclosed in a durable carbon steel coated frame. The integrated vent burst detection sensor allows plant personnel to respond accordingly in the event of an explosion within the protected application.
