The hazardous area industry has been stuck in the past for decades by large manufacturing companies that wish their customers to believe there is no alternative to their long lead, heavy, very expensive and cumbersome Ex d flameproof enclosures for zone 2.
What they don’t tell you is that under the ATEX directive 60079-15, steel panel enclosure manufacturers such as indEx, can self-certify for zone 2, 22, and category 3 solutions.
Type “n” solutions were developed to allow quality industrial components for use in zone 2. That is where a hazardous area material is only present for short periods of time- typically because of a fault somewhere else in the plant area. This means that there is a wealth of solutions available to indEx customers for zone 2, 22 which are not only cost effective, time sensitive and weigh much less than conventional Ex d flameproof enclosures, they also look much better as well!
