Q-Ball® S

Stable + light as a feather for oscillating machines such as vibrating screens.

REMBE® Q-Ball® S
Made in Germany

Flameless pressure relief for dynamic requirements.

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. 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.
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.
REMBE® Q-Ball® S with Accessoires

Sanitary Cover

protects the Q-Ball® S against dust from outside sources.

SK signalling unit

uses the closed-circuit current principle.
  • The only approved flameless explosion venting for oscillating and vibrating systems with high dynamic requirements.
  • Maximum venting efficiency due to spherical quenching factor.
  • Easy maintenance due to integrated inspection opening.
  • Integrated signalling for reliable monitoring.
  • Can be used flexibly indoors and outdoors.
  • Simple retrofitting of existing explosion vent installations possible.
The special stainless steel mesh filter inlet developed by REMBE® cools the hot flame gases extremely efficiently (up to 1.500 °C (2.732 °F). This reduces the volume of gas ejected and extinguishes the explosion.
