Q-Flap RX™ non-return valve
The new Q-Flap RX™ non-return valve is a joint development between REMBE® and the Swiss company RICO. The Q-Flap RX™ is available up to DN 1250.
The strict requirements of EN 16447 are mainly achieved through the very high strengths and flexible installation distances. This is made possible by the so-called swivel carriage principle.
Isolation is essential for an effective Explosion Safety. No matter how much operators invest into (flameless) venting, if an isolation is missing the explosion can spread within the system and continue to propagate from one facility part to another.
Flameless pressure relief for elevators: Q-Ball® E
The Q-Ball® E, which is primarily designed for elevators, uses the principle of the contour-parallel relief developed by REMBE®. Thanks to the innovative design, the weight of the Q-Ball® is very low. While comparable products from other suppliers weigh between 100-200 kg, the Q-Ball® is an absolute lightweight with just 25-50 kg. This particularly facilitates the handling during assembly, as well as the requirements for an installation on the systems in the truest sense of the word.

Michael Hüske, Sales Manager Germany, is especially looking forward to introducing the NIMU to the visitors. It's not the first non-invasive signalling device for rupture discs, but the latest and therefore state-of-the-art technology.
Conventional signalling devices require cables to be mounted on the rupture disc, which must then be routed out through the rupture disc holder. This is not the case with the NIMU. Here, a signal indicator is attached to the rupture disc during the manufacturing process. The actual sensor is screwed into a blind tapping in the rupture disc holder, where it monitors the position of the signal indicator on the rupture disc. This means that the wiring only starts outside the rupture disc holder.
The system is leak-proof, and back in operation quicker
After an overpressure event, and the associated opening of the rupture disc, the outlet part of the rupture disc holder must be removed, the rupture disc replaced, and afterwards the system can be put back into operation. The days when the signalling cables also had to be routed again to the respective switching box are finally over. This allows colleagues from the electrical department to devote their attention to other tasks.
Additionally: The process is absolutely leak-tight. The blind tapping in the holder replaces the tapping which is usually required. The absence of cable glands (required for the holder tappings for conventional signalling cables) means that the cable glands used cannot become porous, thus preventing an escape of the process media.
NIMU, the non-invasive signalling: Sensor in a blind tapping in the rupture disc holder, and signal indicator on the rupture disc.
When the KUB® rupture disc opens, the NIMU sensor will output information to the process control unit of the system.
GRX® - cool and hot
If the process temperature is between -180 °C and 1,500 °C, the process involves corrosive media, and the rupture disc must already respond at a relatively low pressure, then the REMBE® graphite rupture disc GRX® is ideally suited to relieve the pressure. Thanks to a specially developed coating, the GRX® does not require polymeric sealants, and is able to withstand the aforementioned demanding process conditions, while still guaranteeing absolute leak-tightness. This in turn reduces the emissions of the system.

The original of the flameless venting devices, the Q-Rohr®, is now certified for gas explosions. Originally developed for organic dusts, it has also been approved for different types of metal dusts, dual-fuel and gas engines for some time. In the field of gas applications, a broad range of plants in the chemical industry, as well as various test rigs have already been equipped with the Q-Rohr®.
Roland Bunse, responsible for new applications and upgrading (further) development of the Q-Rohr® since the 1990s: "The Q-Rohr® can be used anywhere, where gas-air mixtures could enable an explosion. This is the case in many industries and factories, whereas test benches are only one example thereof. I am looking forward to the upcoming inquiries - of which there are several interesting challenges currently available with very different applications, which we can all protect with the Q-Rohr®."
The Q-Rohr® consists of a explosion vent with a burst indicator, as well as a stainless-steel mesh filter. In case of an explosion the explosion vent of the Q-Rohr® will open, the inserted special mesh filter will efficiently cool down the flames of the explosion and reduce any escaping pressure to a safe minimum. System and environment are therefore ideally protected.

Dr. Johannes Lottermann, Head of Explosion Safety: "To simply sell products is not the key goal in the field of explosion safety. In adherence with our motto “Consulting. Engineering. Products. Service.” we support our customers in every project stage. And to prove our superior performance capability, we had it officially confirmed with the IECEx Certificate.” Congratulation to our colleagues!
An active system is alerted to an explosion at an early stage, when an explosion begins to develop. This is done through sensors or detectors which register the rise in pressure or the formation of flames and respond by activating the relevant isolator, e.g. a quench valve.
Passive isolation, on the other hand, responds purely mechanically to the spreading or loss of pressure, on account of its structural characteristics. This also applies to explosion valves. Under normal operation an explosion valve in a pipeline is kept open by the available flow. When an explosion occurs, the valve is closed by the spreading of the pressure front, thus effectively preventing the pressure and the flames from propagating any further.
In addition to the method mentioned so far, another constructional precaution is explosion suppression. It means eliminating the explosion at its very onset. This is made possible by detectors which register the presence of sparks or flames through sensors and immediately trigger the opening of tanks containing an extinguishing agent (also installed in the system). A highly effective extinguishing agent is released within milliseconds, nipping the explosion in the bud straightaway. If required, an explosion suppression system can also be used for explosion isolation purposes.
