The Q-Rohr-3 system is the only indoor explosion device that meets the NFPA codes and is approved in accordance with EU regulations (ATEX). It consists of an integrated REMBE bursting disc which vents the explosion wave in a controlled manner within the Q-Rohr-3 assembly. Flame gases with temperatures higher than 500° C (2,732° F) are cooled down to less than 90° C (195° F) via energy transfer within the specially developed stainless steel mesh filter inlet. This reduces the expanding gas volume as it extinguishes the flame.
Dust retention is guaranteed by the mesh filter ensuring that no burnt or unburnt dust particles pass through the Q-Rohr-3 assembly. Additionally, the pressure rise and increased noise level associated with free vented explosions are massively reduced to negligible levels. After an explosion event the Q-Rohr-3 is reusable immediately after cleaning and replacement of the REMBE bursting disc assembly
