Indoor Flameless Explosion Venting - Q-Rohr^®-3

During conventional explosion venting, flame propagationas well as shock waves are only permitted to be directed into safe areas.

However, those effects could lead to catastrophic consequences for anyone who is located in the immediate vicinity or surrounding areas. As a certified solution, the Q-Rohr^®-3, with its patented system of flame absorbing and dust retaining materials, guarantees hazard-free indoor explosion venting. 

Difficult to access machines or facilities located amidst production halls can be quickly, simply and safely vented, without cost-intensive, space issues and time-consuming reconstruction. When deploying this maintenance-free protection system: A purely passive solution; no additional operating costs are incurred.

Q-Rohr^®-3 is the only system worldwide that is approved for deployment in Zone 22 according to VDI-3673, DIN EN 14797, DIN EN 16009 and NFPA 68 and certified by FM Global. Insurance companies across the globe recognize the Q-Rohr®-3 as a safe system for flameless explosion
venting.

Flame gases reaching temperatures of up to 2,732 °F (1,500 °C), are instantaneously cooled down via an energy transfer within the specially developed stainless steel mesh filter inlet.

Thus, the emergent resultant gas volumes are reduced and the flames extinguished. At the same time, the typical rise in pressure as well as the noise level associated with an explosion can be reduced to a very low harmless level. The special filter design prevents the escape of the majority of any burnt or unburnt dust particles.
