Explosion-proof idlers, garlands and stations
We are also happy to offer you idlers, idler stations and idler 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 idlers and stations is carried out for all components used by our quality assurance. This concerns not only classic idlers with steel mahntel, but also idlers with lining or rings made of elastic materials such as rubber or polyurethane.
In addition, our idlers, idler garlands and idler stations have the necessary approvals for operation underground.
Our products meet the requirements of the following protection class when properly installed in the overall system:
