Q-Rohr Flameless Venting - The Original
Stay Qool – REMBE Q-Rohr Innovation is a tradition at REMBE. In the area of explosion safety, the invention of flameless venting solutions – the Q-Rohr and Q-Box – is probably the most important in the history of the company. We have continuously developed and improved these products since the 1980s and they are now in use worldwide. The Q-Rohr and Q-Box can be found in a whole range of sectors from the food processing industry to chemicals and pharmaceuticals. The advantages of flameless venting are immediately obvious: the entire production process remains inside the building and there is no need for expensive, bulky venting ducts that require modifications to be made to existing structures. The integrated explosion vent is fitted with a signalling unit that immediately reports any incidents to the process control system. The special stainless steel mesh filter inlet ensures that the pressure rise and increased noise level associated with free vented explosions are massively reduced to negligible levels in the production room. Dust and flames are retained by the mesh filter inlet. The Q-Rohr has a round design. Consequently, it is vacuum resistant and ideal for the protection of pneumatic conveying systems as well as many other applications. The Q-Rohr and Q-Box also compare favourably with active fire extinguishing systems. They generate no running costs, false triggering damages only the bursting disc and the product remains unaffected. No regular maintenance is required, an annual visual inspection is more than adequate. The products are certified by ATEX and also comply with many other currently relevant standards. New: The Q-Rohr can now also be used with metal dusts. Due to their extreme properties in explosive situations (e.g. temperatures can be twice as high as those with most other dusts), metal dusts create special challenges for protection systems. The Q-Rohr is the first system to be certified in accordance with DIN EN 16009.
EXKOP quench valve
Firstly, the tried and trusted EXKOP QV II is now also available for dust class 2 and a reduced explosion pressure (pred) of up to 2 bar. In addition, the launch of the EXKOP QV III, the new big brother of the QV II, means it is now possible to protect lines with diameters of between 300 and 600 mm. With an innovative, space-saving design, it can even be installed in confined areas where space is at a premium. Direct integration of the pressure storage tank keeps the dimensions to the minimum.
EGV HYP - The perfect explosion vent for hygienic applications
The smooth surfaces, in combination with the patented, full surface and tapered sealing concept, enable these special explosion vent to be implemented in previously critical plants, e.g. spray-dryers with/without wet cleaning, fluidized bed dryers, filters and mixers. EGV HYP successfully passed the cleanability tests conducted by the commission of the EHEDG (European Hygienic Engineering & Design Group) and confirmed its suitability for CiP cleaning. The EGV HYP can be adapted to the radius of the container avoiding unwanted dead spaces and making it ideal for use with cylindrical tanks. If the product is to be used in outdoor areas, a closed cell silicon cushion insulation is available to prevent the build up of deposits that may occur when the temperature drops below the dew point. Insulation also minimises temperature and energy losses. These features of the hygienic design of the EGV HYP improve product quality and also protect processes against contamination and production standstills.
KUB® - our most robust rupture disc
REMBE® has developed a unique two-layered reverse acting rupture disc. KUB® is not only extremely easy to install – it is also simple to remove and reinstall. The KUB® design has a unique construction which makes it the most robust rupture disc on the market. KUB® is the ideal solution for a wide range of challenging industrial processes with low to high operating pressures or vacuum, e.g. in liquid, gas or vapour applications as well as in two-phase flow applications.
Q-Flap RX™
Isolation is a decisive component of an Explosion Safety concept. No matter how much operators invest into (flameless) relief - if an isolation is missing, an explosion can spread within the system, and continue to propagate from facility section to facility section. In the worst case, the blast wave will overtake the flames, and the explosion will turn into a detonation. If a sensible isolation is part of the system protection strategy, then there's no reason to worry about such horror scenarios any longer. The Q-Flap RX™ explosion isolation flap valve is a joint development between REMBE® and the Swiss company RICO. "A combination of German engineering and Swiss precision", that's how Dr.-Ing. Johannes Lottermann, Director for Explosion Safety at REMBE® describes the new product. The strict requirements of EN 16447 for the maximum safety and reliability are particularly achieved by the very high strength and extremely flexible installation distances - and all of this thanks to the patented swivel carriage principle. The Q-Flap RX™ is available for all common nominal pipe sizes up to DN 1250.
Q-Ball® E
In addition to the requirement that neither flames nor pressure escape from the protective system, flameless venting devices should also be evaluated in terms of their relief effectiveness and weight. Because: Low efficiencies mean that more relief openings and associated protective systems are required. A too heavy weight requires conversions to the container in order to ensure its stability. The Q-Ball® E has been specifically designed for the protection of mechanical conveyors, which usually have long and sleek geometries. Based on the contour-parallel venting (CPV) invented by REMBE®, the innovative design has resulted in a low weight of the Q-Ball® E while also have a higher effectivity. While comparable products from other suppliers weigh between 100-200 kg, the Q-Ball® E is an absolute lightweight with just 25-50 kg. This particularly facilitates the handling during assembly, as well as the requirements for the installation on the systems.
Q-Bic™
Plant components like silos, mills, filters, collectors, mixers or dryers, in which bulks are processed, conveyed or stored are hazardous areas where fine dust can be found in quantities. Explosion solutions are required when ignition sources cannot be reliably prevented. With use of the Q-Bic™ safety suppression system, the starting explosion is instantly detected by the redundant related detectors and the prompt blowing of dry powder within the endangered area extinguishes the flame. The explosion is extinguished at the point of ignition and cannot be discharged to the outside atmosphere. Q-Bic™ is especially suitable for applications with toxicants, which must not be released in case of explosion.
