REMBE Q‑Rohr® - Flameless Explosion Venting for Indoor Use
This video explains how the REMBE Q‑Rohr® system safeguards indoor equipment such as filters, dryers, cyclones, and pressure vessels against dust and gas explosions.
The system eliminates fire and pressure hazards while maintaining production flow within existing facilities.
Purpose of Flameless Venting
Traditional explosion panels rely on ruptured discs to release pressure. But flames and hot gases still escape. In enclosed spaces, these can cause injury and spread fire.
The Q‑Rohr® offers flameless venting. It provides a safe method to handle explosions without releasing flame or debris into the surroundings.
Design and Function
The Q‑Rohr® uses a stainless steel mesh filter that cools hot gases (up to 1 500 °C or even 3 000 °C for metal dusts). The filter extinguishes flames and retains particles behind a pressure-absorbing structure. This prevents hazardous pressure waves from entering the building.
The system triggers at burst pressures as low as 0.1 bar. It handles pressures up to 2.0 bar and works with dusts having KSt values up to 400 bar·m/s. It supports sizes from DN 200 to DN 800, with custom options up to DN 1400.
Core Benefits
- Flame arresting and particle retention: eliminates fire propagation and pressure waves outside the protected area
- Metal‑dust certification: first system certified to EN 16009 for metal dust applications
- No need for external vent ducts: supports compact layouts and avoids costly installations
- Immediate reuse: after cleaning and replacing the vent, normal operation resumes without delay
- Low maintenance: only a visual inspection is needed. No recurring servicing or sludge disposal
- Flexible placement: can install indoors, even away from external walls
- Integrated signaling unit: supports monitoring and maintenance
- Noise and pressure damping: controls explosion effects to acceptable levels
Model Variants
- Standard Q‑Rohr®: suited for general dust and gas applications
- Q‑Rohr® 6T: designed for metal dusts, certified to EN 16009, ideal for indoor metalworking facilities
- Q‑Rohr® DFE Gas: optimized for gas‑fueled engine exhausts, allows indoor installation and fast restart after activation
- Q‑Rohr® DFE Maritime: certified for marine environments and dual‑fuel engines, supports compact installations in engine rooms
Typical Use Cases
- Indoor dust‑explosion‑prone equipment in food, pharmaceutical, chemical, recycling, or metalworking plants
- Gas‑fueled engine rooms in power plants and ships
- Retrofit projects needing explosion protection without structural changes
Technical Highlights
- Pressure range: 0.1–2.0 bar; KSt up to 400 bar·m/s
- Operating temperatures: −10 °C to +230 °C (or +550 °C for gas variants)
- Sizes: DN 200–800 standard, up to DN 1400 custom
- Certifications: ATEX, EN 16009, EN 14797, NFPA 68, cFMus, DNV‑GL, Lloyd’s, ABS
