Explosion Venting Solutions By IEP Technologies Since 1956

Explosion Venting Limiting the destructive effects of a dust explosion within an industrial process is the goal of a comprehensive safety strategy. One of the most cost effective and proven methods to do so is by using rupture-style explosion venting when the application is suited. When an explosion vent activates, it essentially creates an opening in the process equipment to release the deflagration overpressure and fireball to reduce the residual pressure in the equipment to a safe level. The diagram below shows the pressure development of an explosion in a closed vessel, reaching peak pressures...

Rupture style vents are economical to install and these highly efficient vents fit into the walls of a process volume. They are available in a variety of sizes, configurations and materials to ensure fast reliable operation during an explosion event. Explosion venting is a very cost effective option to limit the destructive overpressure from an explosion however it may be just one component of a comprehensive explosion protection solution. Proper review and design of a comprehensive protection solution will also include suitable isolation methods if required. Our protection specialists are available...

Explosion Vent GE Filter installations with pneumatic cleaning systems and a very high vacuum operation require an explosion vent that withstands vacuum and positive pressure cycling for a long time. For such requirements the GE is the best choice. Its domed design enables negative pressure resistance without the need for an extra vacuum support. The GE type vents feature pressure peak damping as well as integrated flange gaskets. Inside Diam Outside Diam Inside Diam Outside Diam **Chart details standard size vents.

Explosion Vent KE If the negative pressure is not greater than 60% of the rated rupture pressure, installation of a domed vent has no extra benefit. For this application the KE 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 dampening, integrated flange gaskets, cross rib and folded edges are standard KE design features. Inches Outside Width Outside Width **Chart details standard size vents.

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 standard KER design features. Each vent comes with an integrated flange gasket. Millimeters Length Inches Outside Outside Width **Chart details standard size vents.

The round GT type vent is specifically designed for applications with increased Pstat levels. Special applications with elevated operating pressure require explosion vents with static opening pressures that exceed the standard of 0,1barg. The GT type vent series is available from DN 200mm up to DNIIOOmm and can be adjusted with Pstat levels of up to 0,5bar even at elevated process temperatures. **Chart details standard size vents. Contact IEP for any custom requirements** All vents are supplied with “factory-installed” integrated flange gaskets. The standard material is EPDM and can be used from...

Accessories Mounting Frames The necessary outlet flange for types GE / KE can also be supplied. The following material is available: Zinc plated carbon steel or stainless steel. Insulation Insulation consists of a fire-proof mineral wool according to DIN 1259. The insulation is directly mounted to the “vent-side” of the explosion vent and is protected by a light-weight aluminium cover with a water-tight seal. It is secured to the disc to prevent it from flying away during venting. IEP insulation does not have any effect on the venting relief capability or efficiency. This has been proved by notified...

Flameless Explosion Venting In cases where standard explosion venting cannot be used due to the plant part being located indoors or where no means of venting into a safe place can be realised, flameless venting offers a great alternative. The unique IEP Technologies flameless vents are designed to escaping flame front and relieve the pressure to the surrounding in a safe way, without the need for an expendable rupture panel. A flameless venting system always consists of two parts: One is the venting device which is completed with a downstream flame arrester. Whereas the venting device mainly...

The reliable and proven design of the EVN 2.0 Flameless Explosion relief valve offers low profile mounting, low opening pressure and full vacuum resistance. The standard range features an opening pressure of 0,05 bar +/- 20%. Standard range components are made of carbon steel, coated. Special materials are available on request. Each valve is equipped with an opening detection as standard. For specific efficiency values (%EF) mandatory for correct sizing of the necessary relief area, please contact the manufacturer.

The newest addition to the portfolio is the EVN 3.0H Flameless vent. Specifically designed for processes with higher demands to process hygiene and in place cleaning capabilities. The EVN 3.0H features a unique food grade silicone quality lip seal featuring a flush inside geometry and acts as a flange gasket in one unit. The stainless steel valve plate in conjunction with an appropriate shape of the process outlet flange makes it perfectly suitable for processes which demand a low crevice design.
