Rembe, Brilon, Germany, was recently able to demonstrate as part of a notified body inspection during EC type examination tests that its Q-Rohr® flameless explosion venting unit was able to cope effectively with extreme explosion conditions. Using a 26.5m³ test vessel, dust explosions were flamelessly vented by means of a single Q-Rohr unit, with an 800 internal diameter. The company states that previously a controlled explosion of comparable magnitude would have had to be vented by several devices. The secret to its impressive performance is the Q-Rohr’s patented, mechanical design based on the aeronautical principle of stability and flexibility. “The trick lies in riveted components capable of optimally absorbing the explosion’s shockwave. Imagine a rigidly welded aircraft wing: the slightest force would damage the wing and tear it off the body. Riveted wings vibrate, but effortlessly bear extreme forces as well” explained Rembe’s managing director Stefan Penno. www.rembe.de
