Flameless Venting for Elevators and Screens


The Q-Ball® guarantees a safe explosion venting in the operating room. The flame gases are immediately suffocated inside the Q-Ball® through an efficient cooling.

The Q-Ball® is suitable for system components with a low strength as well as dust-explosive systems such as elevators or screens with KSt values < 200 bar × m/s.

Through the low weight, and the high degree of relief effectiveness, you can avoid conversions and attachments to the vessel and reduce the required vent area to a minimum.

Your advantages

  • Maximum venting effectiveness through a contour parallel 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.
