Piab ATEX conveyors

Since there are special safety requirements for equipment and health protection for workers in poten-tially 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 direc-tive 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 and gas: zone 21 and 22 on the outside and zone 20 on the inside and/or zone 1 and 2 on the outside and zone 0 on the inside (under special conditions for use).
Piab’s C and UC series 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 (anti-static) 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.
