SHEET STEEL CONTROL CABINET TREVA ATEX
SAFE STEEL CABINETS FOR EXPLOSIVE ENVIRONMENTS
USE THE CONVENIENT FORM. WE TAKE CARE OF THE REST!
Wherever flammable gases or explosive dust and dust mists occur, the level of safety depends on the choice of components used. If, for example, there are electronic components in the enclosure that can form tiny sparks, e.g. through switching cycles, it makes an immense difference whether an enclosure is sealed or allows gas to enter. The Treva ATEX enclosure series has been specially developed for use in potentially explosive atmospheres. The design and construction of the control cabinet correspond to the Treva series with the advantages of explosion protection.
Just like the Treva enclosure series, the Treva ATEX enclosures have a maximum impact resistance rating of up to IK10. In addition, the housing has a protection class of IP66, which makes it resistant to external influences even under difficult conditions. The wall-mounted housing is made of cold-rolled sheet steel and has an epoxy-polyester paint coating. As an option, the Treva ATEX series is also available in a stainless steel version, which means that in chemical environments, for example, hygiene requirements can be met in addition to explosion protection.
Explosion protection for equipment and protective systems is regulated in Directive 2014/34/EU. The enclosures of the Treva series are certified according to LOM (enclosure with polyurethane seal) or Dekra (with silicone seal). The enclosure series is suitable for use in zones 1 and 2 with respect to gas and 21 and 22 with respect to dust. Treva ATEX offers increased safety according to EN 60079-7, i.e. the prevention of sparks and excessive temperatures.
A 2mm thick mounting plate made of galvanized sheet steel is supplied with the housing. This offers the possibility of mounting the electrical components inside the housing without affecting the housing properties. In addition, the Treva ATEX series offers a wide range of accessories which can be purchased as an option. This includes, for example, a modular frame or an additional inner door. BOXEXPERT’s ATEX cable glands are also suitable for cable entry into the enclosure. These are available in various versions for increased safety (Ex e II) and flameproof enclosure (Ex d II).
