Multi-Layered Explosion Vent – Flat (VNT-XSF) (VNT-XRF)

Robust flat explosion venting panel for excellent service life

Dusty conditions commonly associated with the storage and handling of grains and powders can potentially lead to dangerous explosions. Elfab’s multi-layered bursting panel range combined stainless steel and fluropolymer to create a high performance explosion venting solution. Elfab is unique in having its explosion vents approved as a “protective System” II GD (when used with an Elfab approved Frame).

To meet the relief area requirements of a wide variety of applications, Elfab offers its flat Multi-layered Explosion Vents in a square, rectangular, round or trapezoid construction with a wide range of bolt pattern configurations. This unique range of explosion venting panels are of non-fragmenting design and are available in a selection of sizes. The Multi-layered explosion vent range is suitable for high temperature applications with a standard burst pressure offering of 0.05 or 0.1 BarG @15/30°C with a 25% tolerance.

Offering a low maintenance solution with a dust tight seal and excellent corrosion resistance, this flat non-fragmenting design is now a widely-used explosion protection solution for limited vacuum applications.

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

Elfab’s outstanding in-house manufacturing capabilities and unique process efficiency is enhanced by its state-of-the-art machinery, including a 5-axis laser cutter and extensive testing facilities.

The expanding range of competitively priced, certified opening explosion vents combines Elfab’s distinctive design and manufacturing process with the ability to customise a solution to suit your specific requirements.

Optional integral burst detection for immediate shut-down

Elfab’s flat Multi-layered Explosion Panels are 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 Vent-Tel.
