Flameless Venting panels

Vigilex Flameless Venting Systems

The Vigilex Flameless Venting Panels systems from Atex, offer a safe and effective venting solution for explosion protection of indoor and outside locations, where a safe area cannot be established, near other hazardous processes or in personnel areas. It uses a stainless steel mesh filter to quench vented explosions and arrest flames.

Like all services from ATEX Explosion Hazards, we offer support and maintenance. The Vigilex Flameless vents from Atex offers the latest in flameless venting technology to give your operation the protection it needs.

Vigilex a Versatile, Robust Flameless Venting Panel System

The Vigilex Flameless Vents System was developed in response to a specific need, i.e. explosion venting inside buildings. Traditional explosion venting technologies require a safe venting area (usually outdoors), where there is no risk of secondary explosions or harm to personnel. Explosion vented plant has to be ducted out to a designated (external) safe area (usually within 3 to 6 metres). The only alternative was to strengthen vessels to withstand greater explosion pressures and/or to install relatively expensive explosion suppression systems.

The Vigilex design allows venting of explosions without the attendant risks of an external fireball and without the use of vent ducts. It is essentially a flame-arrester comprising a porous, heat-absorbing surface in the form of an arced quench box. The vented explosion enters the box, the gases are cooled as they pass through the porous surface, dust is filtered out and the flame is quenched. The internal surface-area of the Vigilex Flameless vent is designed so that the effective vent area is almost the same as if the vent itself was free.

The Vigilex Flameless Vent from Atex offer an incredibly effective flameless venting solution for your operation.
