RAX fits an explosion-proof motor marked Ex&nbsp;d&nbsp;IIB&nbsp;T4 (flameproof enclosure, gas group IIB, temperature class T4) and matches the control gear to the zone, so the drive cannot ignite the surrounding atmosphere.<\/p>\n          <p class=\"text-lead\">Hazardous-area suitability is engineered per project against the site&#8217;s zone classification and the ATEX 2014\/34\/EU framework; RAX confirms the motor marking, enclosure and documentation for your specific zone rather than offering a blanket rating. The curtain, guides and hardware are specified to the same duty, and the door ships with full technical drawing and wiring documentation.<\/p>\n          <p class=\"text-muted\"><small>RAX-company facts on this page &mdash; materials, 100,000-cycle fatigue testing, certifications held, warranty and lead time &mdash; are from RAX Door Technology&#8217;s approved brand brief. Industry figures are marked [SOURCED] (with the source) or [ESTIMATE] (industry-typical, not independently verified) in the Basis column and are confirmed against your opening on the technical layout. Fire resistance (EI60\/EI120) and wind-load class are project-specific capabilities we test and document per order &mdash; never blanket certificates.<\/small><\/p>\n        <\/div>\n        <div>\n          <h3>At a Glance<\/h3>\n          <ul class=\"list-check\">\n            <li>Explosion-proof motor marked Ex&nbsp;d&nbsp;IIB&nbsp;T4 (flameproof, gas group IIB, T4)<\/li>\n            <li>Engineered for Zone 1\/2 gas and combustible-dust hazardous areas<\/li>\n            <li>Control gear matched to the site zone classification, per project<\/li>\n            <li>Suitability confirmed against the ATEX 2014\/34\/EU framework per project<\/li>\n            <li>100,000-cycle validated; CE to EN&nbsp;13241; custom engineered to your specification<\/li>\n          <\/ul>\n        <\/div>\n      <\/div>\n    \n      <div class=\"page-actions\" style=\"margin-top:2rem;\">\n        <a class=\"btn btn-primary\" href=\"https:\/\/www.raxdoors.com\/contact-us\/\">Get a Free Quote<\/a>\n<\/div>\n    <\/div>\n  <\/section>\n\n  <section class=\"section-dark section\">\n    <div class=\"container-xl\">\n      <div class=\"section-heading\">\n        <span class=\"eyebrow\">02 &middot; Technical Data<\/span>\n        <h2>Technical Specifications<\/h2>\n        <p class=\"lead\">Every door is engineered to your opening.
