Determining the explosion parameters in the design of dust collection systems

Dust analysis by Keller sets matters straight

As a result of EU guideline ATEX 137, system operators of machines at risk of explosion are required to determine
and evaluate the risk of explosion by filing an explosion protection document. To fulfill this requirement it is frequently
necessary to determine explosive dust parameters, among other issues, for the suitable design of dust collection systems. Keller is capable of providing the necessary support for the evaluation of the explosion hazard, the detection of
the explosive parameters and establishing explosion protection measures with interrelated service packages.
