Product description

Explosion Diverters were probably the most original variant for protection against dangerous flame radiations in interconnected containers. The advantage of this method was always that it provided protection in both directions as it allowed pressure to be reliably decoupled at the explosion diverter, irrespective of whether the explosions came from the extractor or filter sides.
But DIN EN 16020:2011 has created a way of using explosion diverters safely. The testing procedures that it specifies with the design regulations and the detailed catalogue of requirements that it contains clearly set out the demands that such diverters must satisfy, if they are to be used in protective systems.
Classical geometries defined in the standard produce pressure losses of up to 1500 PA, which would require huge additional fan performance to compensate.
However, new flow-simulation programs now make it possible to reduce pressure losses with standard-compliant designs by over 60% to 550 Pa. This means that, technically, the loss of pressure has been reduced to the levels that can be achieved with non-return valves - which for many years have been broadly accepted as cost-effective decoupling systems.
