VIGILEX VQ: FLAMELESS EXPLOSION VENTING
DESCRIPTION

To protect indoor machinery the model, VQ, guarantees flameless venting and dust protection. No burnt or unburnt dust passes off. Even high temperature is reduced to a minimum. During normal venting an explosion is freely discharged, allowing flames and dust to exit from the process vessel. When the process is located indoors, ducts are generally used to convey the explosion outside the building. However, the cost and options of implementing explosion vents and ducts are limited.

 

Model VQ is an ATEX approved flameless explosion vent. It is used with great effect indoors and outdoors. It is the best and easiest solution instead of cumbersome and expensive solutions with pipe installations to the open air. The VQ provides low pressure resistance effectively eliminating flame and heat emissions thereby easing indoor installation and positioning of relevant machinery.

 

VQ is rectangular and supplied with a standard rectangular bursting panel and it is available in different sizes. A burst sensor is included in the delivery. Model VQ is certified by the French notified body INERIS and will comply with the latest standard for Flameless Explosion Venting Devices: EN 16009 : 2011.
