Perfect protection of the environment.

Made in Germany
The Q-Box® is designed for plant components that are at risk of dust explosions, such as filters, elevators or silos with KSt-Values less than 200 bar × m/s and large explosion venting areas.
The rectangular connection complements the dimensions of standard explosion vents, thus allowing it to be retrofitted to existing indoor and outdoor equipment. The sanitary cover protects the Q-Box® against dust from outside sources. Q-Box® is also suitable for outdoor application. Easy retrofitting: The dimensions of the Q-Box® perfectly match the dimensions of REMBE® standard explosion vents.
REMBE® Q-Rohr® with Accessoires

Sanitary Cover

protects the Q-Box® against dust from outside sources.
  • Flexible use of the Q-Box® permits process-efficient plant design.
  • Reduces noise levels.
  • Perfect protection of the surrounding area.
  • Neither heat, dusts nor a dangerous pressure wave emerge from the vessel – everything stays in the Q-Box®.
  • Cost-effective alternative to venting ducts. No running costs for venting ducts and external maintenance, a visual inspection is sufficient.
  • Integrated signalling unit for reliable monitoring.
  • Reduced downtime: Access to the protected system doesn't require a safety-related locking mechanism (LOTO).
  • Flexible solution for indoor and outdoor use.
  • Simple retrofitting to existing explosion vent installations.
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.
