Since there are special safety requirements for equipment and health protection for workers in potentially explosive atmospheres the EU has created legislation for this called the ATEX directives. (ATEX is an abbreviation for Atmosphère Explosible). Equipment that is certified according to the ATEX directive 94/9/EC has to be designed in a way that it can not cause an explosion during its intended use.
Piab can offer conveyors for ATEX applications. Those conveyors are type examined according to ATEX by a third party. Piab has a quality management system which fulfils the high standards that is required for delivering ATEX equipment on a regular basis.
The conveyors fulfil the requirements for the following ATEX zone classification for dust: zone 21 and 22 on the outside and zone 20 on the inside.
Piab’s conveyors that are classified for use in potentially explosive atmospheres have specific features.
- All seals/rubber parts between the machine’s sheet metal parts are made of dissipative (antistatic) materials.
- All larger plastic parts are made of dissipative (antistatic) materials.
- As a consequence of this, only antistatic variants of filters and fluidisation cones are used.
An ATEX-certified conveyor is delivered with CE Declaration of conformity and CE marking, which for example clearly states the ATEX classification and contains the EX symbol.
