Q-Ball® S

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

REMBE® Q-Ball® S

Flameless pressure relief for dynamic requirements.

The Q-Ball® S guarantees safe indoor explosion venting. Efficient cooling inside the Q-Ball S prevents escaping flames and pressure effects that otherwise result from an explosion. A specially designed substructure and minimal power-to-weight ratio allow the Q-Ball® S to be attached directly to the oscillating system. The Q-Ball S, with its newly developed spherical quenching factor , ensures maximum venting efficiency so there are no costly extensions or conversions. This provides optimized protection by reducing the required vent area.
The Q-Ball® S, unlike conventional flameless explosion venting devices, was therefore specifically developed and customized for oscillating and vibrating plant components with additional high dynamic requirements and KSt values up to 265 bar*m/s.

Sanitary Cover

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

SK signaling 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 signaling 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 2.732 °F (1.500 °C). This reduces the volume of gas ejected and extinguishes the explosion fireball discharge.
