Flameless Venting

Q-Rohr®

Safe and cost-effective solution for indoor applications.

 

Safety and operating efficiency go hand in hand.The Q-Rohr® enables you to implement flame arresting and particulate retention explosion venting inside facilities. No complicated ducts for outdoor venting or associated restructuring of production equipment are required. With the Q-Rohr® there is now nothing to prevent you from using the optimum layout for your production plant while guaranteeing the best possible explosion safety. In addition, Q-Rohr® is unrivaled in terms of operating cost. Eliminating vent ducts saves you money not only on installation but also on servicing and maintenance. Q-Rohr® is also suitable for metal dusts, gas and hygienic applications. Q-Rohr® is available in the sizes DN 200 to DN 800. Customized versions up to DN 1400 are also possible.

The all-rounder.

Application

The Q-Rohr® is ideal for indoor plants that are at risk of dust and gas explosions. Many new plants are equipped directly with the Q-Rohr® as it offers a wide range of flexible installation options. Retrofitting is also simplicity itself. The Q-Rohr® can be used to protect filters, dryers, cyclones and can be used with gases, hybrid mixtures, metal dusts, melting dusts or fibrous dusts.

Mechanism

The hot flame gases, which can reach temperatures of up to 2.732 °F (1.500°C), are cooled extremely efficiently in the special stainless steel mesh filter inlet developed by REMBE®. This reduces the volume of gas ejected and extinguishes the explosion flame discharge.

Rupture Disk

The disks provide reinforcement.

Seal

The seals are available for all process conditions: Also suitable for high temperatures or sterile requirements.

  • Perfect protection of the surrounding area. Guaranteed flame arresting and particulate retention – no hazardous pressure wave effects.
  • REMBE® is the first manufacturer in the world to be certified for metal dusts.
  • The complete production process remains in the building.
  • No reoccurring costs for vent ducts or external maintenance, a visual inspection is sufficient.
  • The Q-Rohr® is a flexible solution – it can even be used in the middle of your production halls. Proximity to an external wall is not required.
  • Integrated signaling unit for reliable monitoring.
  • Noise level and pressure rise typically associated with explosions are greatly reduced to an acceptable harmless level.
  • Immediately reusable and operational after cleaning of the flame filter and replacement of the explosion vent.
  • Process-optimized plant layout.
  • No external maintenance costs.
