30+ years of combined experience in ATEX/IECEx designs
Our Team
At ZELX, our team combines over 30 years of experience designing equipment for use in explosive atmospheres. Together, we bring:
- Deep Standards Expertise: Active participation in international standardisation, including IEC technical committees shaping the future of explosive-atmosphere requirements.
- Proven Design Track Record: Experience across intrinsically safe IoT, wearables, non-electrical equipment, and all major protection concepts (Ex i, Ex d, Ex e, Ex p, etc.).
- Collaborative Network: Beyond our core team, we partner with a trusted group of high-level engineers and specialists to deliver projects of any scale.
Our shared mission is to help manufacturers shorten certification paths, reduce risks, and bring safe, compliant products to global markets.
From Concept to Certified Product
Electronic Design
We develop safe and reliable electronic systems for hazardous environments — from IoT devices to advanced instrumentation. Every design balances performance, compliance, and manufacturability.
Mechanical Design
Our mechanical engineering expertise ensures robust enclosures, thermal management, ingress protection, and ergonomics, all tailored to meet ATEX, IECEx, or NEC requirements.
End-to-End Development
From early prototypes to final certification, we guide products through every stage of the journey — transforming concepts into real, compliant, and market-ready equipment.
Global Ex Approvals Expertise
We don’t just design equipment — we navigate the world’s approval systems from the inside out. Our team has hands-on experience with all major international Ex certification schemes, including:
- Europe: ATEX Directive 2014/34/EU
- International: IECEx System
- North America: NRTL approvals, Class/Division (NEC 500 & 505, NFPA 70)
- Middle East: ECAS-Ex (UAE) and regional schemes
- South America: INMETRO (Brazil)
- Global Reach: Many regions follow IECEx or North American frameworks, making our expertise universally applicable
We help manufacturers understand requirements, avoid pitfalls, and bring products to market faster — anywhere in the world.
