Flameless Venting for Elevators

The Q-Ball® E guarantees safe explosion pressure relief in the operating area. Efficient cooling inside the Q-Ball® E prevents the flames from escaping and eliminates pressure effects as a result of the explosion.

The Q-Ball® E is suitable for flameless venting of mechanical conveyors with low design strength such as elevators. Explosions with KSt values up to 200 bar × m/s can be handled.

The connecting dimensions of the Q-Ball® E perfectly complement the standard sizes of mechanical conveyors such as elevators.
This avoids the need for work-intensive adjustments of the flanges. Due to the low weight of the Q-Ball® E, any reinforcements of the conveyor‘s shaft also become unnecessary. With the newly developed principle of full body flameless venting, the Q-Ball® E ensures maximum relief efficiency. The necessary relief area can thus be reduced to a minimum.

Your advantages

  • Maximum venting efficiency through a full body flameless venting.
  • Easy maintenance through an integrated inspection opening.
  • Integrated signalling for a reliable monitoring.
  • Can be utilized flexibly indoors and outdoors.
  • Easy retrofitting of existing vent panels installations possible.
