Domed Explosion Vent

Multi-Layered Explosion Vent – Domed (VNT-XSD) (VNT-XRD)

Excellent service life for processes with medium vacuum and back pressure conditions
The storage and handling of grain and powders inherently produces dusty conditions that can lead to potentially dangerous explosions. Elfab’s explosionventing panel range offers protection against such disasters. Elfab is unique in having its panels approved as a “protective System” II GD (when used with an Elfab approved Frame).

Its domed design Multi-Layered Explosion Vent brings the additional benefit of enhanced operating performance under cyclic pressure, back pressure and vacuum conditions. With the highest Operating Ratio across the Elfab explosion panel range of 80%, this distinctive bursting panel allows for enhanced cycling characteristics.

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 option to tailor a solution to meet your exact requirements.

To meet the relief area requirements of a wide variety of applications, Elfab offers its Multi-layered Explosion Panels in a square, rectangular, round or trapezoid construction with a wide range of bolt pattern configurations. This unique range of non-fragmenting bursting panels is available with a standard burst pressure of 0.05 or 0.1 BarG @15/30°C with a 25% tolerance. Elfab’s multi-layered design venting panels are suitable for use in high temperature conditions.

Optional integral burst detection for immediate shut-down
Elfab’s Multi-layered Explosion Vents 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.

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.
