All equipment in this category meets the rigorous safety requirements for classified hazardous locations. Independent certification to ATEX, IECEx, and UL standards verifies that each unit has been tested for use in explosive atmospheres found in petrochemical facilities, offshore platforms, grain handling operations, and chemical processing plants. These certifications are renewed on a defined schedule to reflect any design changes and to maintain compliance with evolving international standards.
Proper product selection depends on your site classification, mounting requirements, and operating environment. Class I Division 1 and Zone 1 environments demand the highest level of enclosure protection, while Division 2 and Zone 2 locations may permit designs with a lower protection level. Working with a certified hazardous-area specialist before finalising your specification helps ensure the installation meets both local electrical codes and applicable international standards without over-specifying the hardware.
Professional installation is strongly recommended for all hazardous-area equipment. Installers experienced with NEC Article 500 and IEC 60079 can verify that cable entries, conduit seals, and grounding connections are completed correctly and documented for compliance records. Veilux supplies full technical documentation, certified installation drawings, wiring diagrams, and post-installation support for every product in our catalog at no additional charge.
