When a combustible material, an ignition source and atmospheric oxygen collide in a confined space, the result is an explosion. Preventative explosion safety measures aim to stop this potentially lethal mixture from occurring. However, in practice, the vast number of potential ignition sources alone almost always makes this impossible. Consequently, the most important safety features for industrial companies are protection measures that minimise the damage caused by an explosion. Industrial plants must always be protected against the consequences of explosions to ensure that employees are safe and production can be resumed quickly. After all, every hour of lost production costs money. In most cases, explosion safety can be provided cost-effectively through explosion venting and explosion suppression.
We will be pleased to show you solutions tailored to your processes that will reduce the damage caused by an explosion to a negligible level – enabling you to resume production quickly after an explosion.
All REMBE® explosion vents are Made in Germany and certified in accordance with directive 2014/34/EU (ATEX) and EN 14797.
The right bursting disc for all applications + operating conditions.
In the case of a deflagration, an explosion vent will rupture and thus protect the vessel by reducing the overpressure within it and releasing the explosion into the surrounding environment in a controlled manner. Industrial processes vary widely depending on the sector and the product. No two processes are identical. For this reason, REMBE® supplies explosion vents in a variety of different shapes, materials, temperature- and pressure resistances and many other specifications. we can supply you the optimum REMBE® explosion vent for your requirements. You will receive a complete protection concept that is perfectly adapted to your process.
Explosion isolation systems use components such as quench valves and non-return flaps or valves. Chemical extinguishing barriers are also commonly used to smother the explosion flames. Valves and extinguishing barriers are capable of isolating components in both directions simultaneously. Active systems have detectors or sensors which register the pressure rise or flames and trigger countermeasures, e.g. closing a valve. Passive isolation systems react simply due to the effect of the explosion. Their structural design prevents flames and pressure waves from spreading. The objective of explosion isolation or decoupling is to protect adjacent parts of the plant and prevent the explosion from propagating.
Explosion suppression is an explosion protection measure in which the combustion of an explosive atmosphere in a closed or essentially closed volume is detected (recognised) and stopped in the initial phase, thus preventing destructive pressure increases. A controller initiates the sudden release of extinguishing powder from the extinguishing bootle into the volume to be protected in the shortest possible time. An explosion is considered suppressed if the explosion pressure does not exceed the engineered strength of the affected volume, or the degree of flame propagation remains within the specified limits in open spaces.
During flameless explosion venting, the flames are cooled rapidly and efficiently in the mesh filter of the flame absorber and extinguished immediately. No flames and no pressure wave exit the vessel. The production plant can now be designed to create the optimum process conditions. Likewise, the typical pressure wave and noise in the production hall are reduced to a barely perceptible minimum. The filter design guarantees that no burned or combustible materials are ejected. This does not only reduce the consequences of the explosion, it also provides the highest level of protection for employees.
Electrostatic charges on the surface due to friction of chargeable materials. This charge remains on the material until it either slowly degrades or unloads by arcing to a conductor. The sparks which develop from this discharge can cause an ignition in the event of an explosive atmosphere. To prevent this electrostatic charging, and provide a safe derivation of charges, the use of suitable grounding systems is required such as, for example, grounding clamps on barrels, equipment and pipes. Grounding clamps are to be used especially for mobile objects, because quick installation and dismounting of the grounding clamps is possible.
In the event of an explosion, signaling enables the system to be shut down quickly and decoupling systems to be triggered to protect adjacent parts of the system. Automated processes also use intelligent signaling systems in order to be constantly informed about the status of the entire system and any faults. This is not only mandatory in vent ducts, but can also play an important role in free reliefs. Already installed bursting discs can be retrofitted with signaling. To evaluate the signals, we offer you an isolating switching amplifier with a relay output, which ensures an intrinsically safe quiescent circuit. The potential-free relay contact is used for safe system shutdown or alarming.
