Ensuring safe operations in hazardous areas is critical for industries handling flammable liquids or gases. LDI’s Remote Optical Watcher (ROW) stands out with its ATEX and IECEx Zone‑1 certified model—offering unmatched performance in explosive environments. This certification not only ensures regulatory compliance but also delivers peace of mind for operators working in high-risk contexts.
Understanding ATEX & IECEx Zone‑1 Certification
ATEX Zone 1 refers to environments where explosive atmospheres from flammable gases or vapors are likely to occur during regular operations. IECEx complements this by offering a globally recognized scheme for equipment certified for such conditions.
Achieving Zone‑1 compliance involves rigorous design and testing to ensure that under fault conditions, the equipment cannot ignite an explosive atmosphere—making it essential in sectors like oil & gas, petrochemicals, and fuel handling.
ROW ATEX EXD: Certified for Compliance and Safety
ROW’s ATEX EXD model (O‑2301E/O‑4501E) comes in a flameproof, 316L stainless steel casing, certified by third parties such as DNV. It meets ATEX/IECEx Zone‑1 standards while delivering:
-
IP68 water and dust protection
-
Detection of oil films as thin as 1 µm
-
Detection range up to 8 m
-
Robust functionality in –25 °C to +60 °C environments
This model is ideal for monitoring in hazardous settings like fuel depots, petrochemical plants, and marine terminals.
Compliance Benefits: Why Certification Matters
1. Enhanced Safety
Zone‑1 certification prevents explosion hazards even under fault conditions, significantly reducing risk to personnel and equipment .
2. Regulatory Trust and Market Access
ATEX and IECEx are recognized worldwide, easing international deployment and avoiding redundant testing and paperwork
3. Operational Reliability
Quality-certified equipment ensures consistency, reduces downtime, and avoids the hidden costs of unplanned failures or compliance breaches.
4. Insurance & Cost Advantages
Regulators and insurers favor certified systems, leading to improved coverage terms and lower insurance costs over time.
