REMBE® Explosion Safety
Hazard Oriented. Risk Appropriate. Reliable. Sustainable. Authentic. Safe.
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 steps towards explosion safety for industrial companies are protection measures that minimize 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 quickly resume. 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 are 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 NFPA compliant and are certified in accordance with directive 2014/34/EU (ATEX) and EN 14797.
Deflagration Venting with Explosion Vents
The right explosion vent for all applications and operating conditions.
In the event of a deflagration, an explosion vent will rupture, protecting the vessel by limiting the overpressure within it. The explosion is released 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 explosion vent for your requirements. You will receive a complete protection concept that is perfectly adapted to your process.
Explosion Isolation
Comprehensive protection for your plant.
Explosion isolation systems use components such as quench valves and explosion isolation flap valves. Chemical extinguishing barriers are also commonly used to smother propagating explosion flames. Valves and extinguishing barriers are capable of isolating components in both directions simultaneously. The objective of explosion isolation or decoupling is to protect adjacent parts of the plant and prevent the explosion from propagating. Explosion isolation is mandatory – secondary explosions in interconnected vessels would create a high-risk situation. Active systems have detectors or sensors which register the pressure rise or flames and trigger countermeasures, e.g. closing a valve.
Explosion Suppression
Nips the explosion in the bud.
Explosion suppression is an explosion protection measure in which the combustion of an explosive atmosphere in a closed or essentially closed volume is detected and stopped in the initial phase, thus preventing destructive pressure increases. A controller initiates the sudden release of extinguishing powder from the extinguishing bottle 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 specified limits and directed into safe open spaces.
Flameless Venting
Deliberately not on fire.
As early as 1988, REMBE® developed the first flameless explosion venting system. It was based on a process in which the flames are cooled extremely efficiently in the mesh filter of the flame absorber and extinguished immediately. The typical pressure waves and noise pollution that occur outside the vessel during an explosion are reduced to a harmless level. This guarantees maximum protection for employees and, in addition, allows the production plant to be set up in a process-optimized manner. Flameless indoor explosion venting makes expensive protection systems and complicated vent ducts a thing of the past.
Explosion Prevention
Warns you before things 'heat up'.
Prevention aims to eliminate combustible materials, explosive atmospheres or effective ignition sources. If the process itself could lead to ignition risks, the use of ignition source control by preventative safety systems is required to reduce the risk for both, plant personnel and the installation itself.
Accessories
Accessories for your explosion vents.
In the event of an explosion, signaling units enable you to shut down a plant quickly in the event of an explosion and trigger isolation systems which protect adjacent parts of the plant. Automated processes also use intelligent signaling systems to monitor the status of the entire plant and any disruptions that occur. This is not only essential in venting ducts, it can also play an important role in free venting. Signaling units can be retrofitted to vents that have already been installed. For evaluation of the signals, we offer isolation amplifiers with relay outputs which guarantee an intrinsically safe closed-circuit current. The potential-free relay contact ensures that the plant is deactivated safely and the alarm functions correctly.
