Dynamic flameless explosion venting for oscillating machines such as vibrating screens

The Q-Ball® S guarantees safe indoor explosion venting in the operating area. An escape of the flames as well as pressure effects as a result of the explosion are prevented inside the Q-Ball® S by efficient cooling.

The Q-Ball® S, unlike conventional flameless explosion venting devices, was therefore specially developed and customized for oscillating and vibrating plant components with additional high dynamic requirements and KSt values up to 265 bar*m/s.

A specially designed substructure and minimal power-to-weight ratio allow the Q-Ball® S to be attached directly to the oscillating system. There are no costs for extensions or conversions with the application of the newly developed spherical quenching factor, the Q-Ball® S ensures maximum venting efficiency. The required venting area can thus be reduced to a minimum.
