ATEX conveyor rollers

Explosion-proof conveyor rollers, garlands and idlers

We are happy to offer you conveyor rollers, idlers and roller garlands specially designed for use in potentially explosive atmospheres (ATEX). We enclose a corresponding declaration of conformity according to EC Directive 2014/34/EU with the correspondingly marked products.

The testing of the leakage resistances to ensure the electrical conductivity of the conveyor rollers and idlers is carried out for all components used by our quality assurance. This concerns not only classic conveyor rollers with steel tubes, but also conveyor rollers with coating, lagging or rings made of elastic materials such as rubber or polyurethane.

In addition, our conveyor rollers, roller garlands and idlers have the necessary approvals for operation underground, e.g. in deep coal mines.
