Q-ROHR® G Flameless venting for gas applications The Q-Rohr® G enables economical flameless venting without any cost-intensive conversion measures like the creation of wall openings. GBPI-QR3-G-16222/1 | © REMBE | All rights reserved | Valid from 10.10.2023 | Subject to technical change without notice Reliable protection against gas explosions Are you looking for an economical solution to relieve gas explosions without emissions and without complex additional installations such as catch baskets? That is exactly what the Q-Rohr® G can offer you. With a quick installation and its minimal dimensions, it can adequately protect systems, peripherals and the environment from the effects of a gas explosion. Production can be quickly resumed again after an explosion event: Simply replace the explosion vent. However, the Q-Rohr® itself only needs to be refurbished after three explosions. Mechanism The flame gases, which can reach a temperature of up to 1,500°C, are cooled down extremely efficiently in the special stainless steel mesh filter inlet developed by REMBE®. This reduces the discharged gas volumes, thus extinguishing the explosion. Your advantages ✓ Rapid restart of operations. ✓ REMBE® stainless steel filter ensures a high level of noise reduction during normal operation and in the event of an explosion. ✓ Eliminates the need for complex vent ducts and wall openings. ✓ 100% leak-tightness, to eliminate danger of asphyxiation. ✓ 100% venting efficiency. ✓ Individually definable opening pressure. ✓ 100 % stainless steel for corrosion resistance. ✓ Connection flange in accordance with EN 1092-1 standard and DIN 86044. ✓ No separate safety zones required in outdoor areas. ✓ No maintenance required, visual inspection by a technician is sufficient.
