Single Skinned Explosion Vent - Flat

The most cost-effective explosion venting protection to better suit your individual process conditions

Dusty conditions commonly associated with the storage and handling of grains and powders can potentially lead to dangerous explosions. Elfab’s Single-Skinned bursting panel range offers reliable and efficient protection against such disasters in conditions requiring limited vacuum capability. The flat non-fragmenting design is especially suitable where a low profile solution offers an advantage to the silo construction.

Available on Express lead-time for improved supply chain management 

Elfab’s outstanding in-house manufacturing capabilities and unique process efficiency means that it is able to offer customers a very quick product turn around to minimise down time in the case of an emergency. This flexibility also enhances the effective management of its customer’s supply chain.

Custom manufactured using outstanding in-house processes to meet your requirements

Elfab has advanced 5-axis laser cutting and extensive testing facilities that enable us to produce competitively priced, certified opening explosion vents in a wide range of configurations and bolt patterns. The range combines Elfab’s unique design and manufacturing process with the ability to tailor the solution to suit your exact needs.

To meet the relief area requirements of a wide variety of applications, Elfab offers its Single-Skinned Explosion Panels in either a square or rectangular design. Due to its construction, this unique range of bursting panels represents a cost-effective solution, while continuing to offer high performance and corrosion resistance. This non-fragmenting design is available in a wide range of sizes with wide temperature compatibility and its standard burst pressure is 0.1 BarG @ 15/30°C with a 25% tolerance.

Optional integral burst detection for immediate shut-down

The Single-Skinned Explosion Panel is available with the optional benefit of an integral burst detection system for instantaneous notification when panel has burst. Elfab’s unique ATEX-approved burst detection system, Vent-Tel, was specifically designed for its range of explosion venting panels to further ensure onsite safety for its customers. Vent-Tel is a non-invasive, fail safe, burst detection system providing an excellent solution for identifying when an explosion panel has functioned under harsh operating conditions.

Operating on a simple reed switch and magnet technology, Vent-Tel is designed to offer a practical solution for explosion vent burst detection. The magnet is pulled away from the sensor in the event of a panel burst, giving an open circuit signal. It signals a burst within the installation and in turn, can trigger an immediate shut-down of the process.

When connected to an intrinsically safe circuit this ExII 1GD EEx ia IIC detection device ensures a safe and compliant plat that fulfils the demanding regulatory developments within the bulk handling industry. An EC-Type Examination Certificate ITS03 ATEX 11359 is available.

Existing explosion venting panel installations without a burst detection system can be retrofitted with the Vent-Tel system.

  • Lowest profile possible
  • Resistant to abrasion, corrosion and moisture
  • Maintenance Free
