Atex certificate for Active SOliValve
What is ATEX?

The ATEX directive consists of two EU directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. All companies in the EU must follow these regulations since 2003.
The main goal of these directives is to protect the employees working in an explosive atmosphere by avoiding explosion risks.

Explosive Atmosphere in powder handling

An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapors, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.

In powder transfer, the risk of explosion is common, either because the very small particles can get statically charged during the filling/discharging process or where the powder is mixed with solvent, like in a reactor for example.

Reducing the Explosion class with SoliValve

The ATEX directive classifies the Explosion risk in 3 zones for gases (0,1, 2) and 3 zones for dust (20, 21, 22). More details available here.

Thanks the dust free powder transfer achievable with the SoliValve system, the ATEX class can be reduced, for example from zone 20 to 21, or from zone 21 to 22.

What does it mean exactly?

Firstly, it means, a safer working environment for your employees. Secondly, it means investment savings for you, because reducing the ATEX class means reducing the amount of specific and expensive equipment require to fulfill the EU ATEX directives.

With SoliValve®: Safety for your employees + investment saving thanks to reduction of explosion class.
