The principal of flameless venting is a Rembe invention from the 1980s, which has changed the world of Explosion Safety like no other. It all started with the Q-Rohr, and is now continued with the Q-Ball. In addition to the requirement that neither flames nor pressure escape from the protection system, flameless venting devices should also be evaluated in terms of their venting efficiency and weight. Because: Low efficiencies mean that more / bigger venting areas and associated protection systems are required. A too heavy weight requires conversions to the vessel in order to ensure its stability.
Very low weight
The Q-Ball, which is primarily designed for elevators and screens, uses the principle of the parallel contour relief developed by Roland Bunse. Thanks to the innovative design, the weight of the Q-Ball is very low. While comparable products from other manufacturers weigh around 45 kg, the Q-Ball which only weighs around 25 kg is an absolute lightweight, and 3 kg lighter than the Q-Box, the previous record holder in terms of weight.
