Non-invasive, ATEX approved, reusable burst detection

Vent-Tel is a non-invasive and fail-safe burst detection system. Operating via a simple N/O reed switch and magnet technology, the detector can trigger a safe and rapid shutdown of the process should an overpressure event occur.

Sanitary applications

Vent-Tel can be fitted to the full range of Elfab’s sanitary discs, including our innovative sanitary rupture disc solution, Pure-Gard. The detector is an independent, reusable solution mounted directly to the Tri-Clamp, making disc inspection and replacement quick and simple.

In addition, as Vent-Tel is non-invasive to the process, it does not need to be replaced after a pressure event: it remains in situ and connected to the control system. It can be reused with the new, replacement disc.

This detection system is compatible with ferrule and NAC pad type connections.

Explosion vents

When fitted to explosion panels, Vent-Tel (previously known as Panel Flo-Tel) provides an instantaneous signal of panel actuation within any application. Being non-invasive, Vent-Tel is not susceptible to process change or false signals and does affect the performance of the panel. Vent-Tel can also be retrofitted to our range of explosion panels.
