Among the most significant risks that extraction systems face are fires and explosions. Even if extraction systems feature additional preventative measures such as spark extinguishers, the possibility of these events cannot be ruled out altogether. For this reason, filter systems and silos must be protected by structural explosion protection measures, such as decompression and decoupling, which help prevent fires from spreading.
Scheuch has developed preventative, structural safety packages with your protection in mind:
In cases where extraction pipes need to penetrate fire compartments that have been installed in order to comply with building regulations and automatic fire barriers that are suitable for pipes carrying materials must be installed.
These barriers feature a controlled locking mechanism that operates as follows:
Fire protection flaps in ventilation areas are not compatible with this type of solution.
Establishing a large distance from the exterior wall to the filter and factory hall is a problem that is familiar to many businesses, but fire-resistant walls come with a hefty price tag. Now we have developed an alternative that offers the same level of fire protection – a solution that takes up very little space and does not require any fire-resistant walls. As a result of tests performed by the recognised testing institute IBS, the filter housing and the separators between the filter and factory hall have been given the fire resistance classification EW 120. Thus, Scheuch filtration systems require a protection area of only one metre.
This is what the Scheuch BRANA 120 fire protection concept offers:
Thanks to the many practical trials it has performed in complete systems, Scheuch has what it takes to develop the right concept for every application. The ROWEK 65 explosion protection concept, for instance, ensures flame propagation of less than five metres in emergency situations. Even in cases where space is restricted, filter systems can be installed in a way that makes them easy to work with. What is more, the exceptionally low explosion pressure incorporated into the design means that, if an explosion does happen, new filter bags can be fitted and the system can continue being used. The result is hardly any interruption for the operator and low repair costs.
Even if silos feature additional preventative measures such as spark extinguishers, the possibility of fires or explosions affecting them cannot be ruled out altogether. For this reason, they must be protected by structural explosion protection measures, such as decompression and decoupling, which help prevent fires from spreading.
