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. The new Q-Ball flameless venting device (photo), which is primarily designed for elevators and screens, uses the principle of parallel contour relief developed by Roland Bunse. Thanks to this unique design, the weight of the Q-Ball is very low. While comparable products weigh around 45 kg, the Q-Ball only weighs around 25 kg, and is 3 kg lighter than the company’s similar Q-Box product. — Rembe GmbH Safety + Control, Brilon, Germany
