The Wolf Towerlite WTL-575-230 is a high-performance, portable ex-proof tower-style lighting system designed for the illumination of very large areas in hazardous locations. Offered by IST Safety Ltd, the official distributor of Wolf, this system is specifically optimized for large-scale industrial operations and outdoor field works requiring high-level overhead lighting.
Certified for Zone 1/21, the Towerlite delivers ultra-high light output through its 575W metal halide lamp. With a robust and corrosion-resistant aluminum body, stainless steel mounting components, and an IP66 ingress protection rating, it has proven its reliability in the harshest outdoor conditions, from shipyards to oil refineries. Capable of being integrated with telescopic tripod systems or fixed tower structures, this solution illuminates vast sites with daylight clarity to maximize operational safety and efficiency.
The WTL ATEX Towerlite™ is a robust, transportable tower light solution certified for ATEX, IECEx, and UKEX Zone 1, 2/21, 22. It extends up to 5.4 meters and features three adjustable LED LFX2 Floodlites, providing up to 78,000 lumens of bright light for illuminating medium to large indoor or outdoor areas.

What is ATEX and what does exproof mean? The ATEX directive is a set of European Union standards that define the safety requirements for equipment used in hazardous areas with explosive atmospheres. Exproof (Explosion-proof) refers to protection methods designed to prevent explosions by inhibiting the formation of sparks or electrical arcs in environments containing flammable gases, dust, or vapors. To ensure life and property safety in industrial facilities, the use of ATEX-certified exproof devices is a legal requirement.
ATEX Zone coding is a technical classification based on the frequency and duration of the occurrence of an explosive atmosphere in a given area. While the terms Zone 0, 1, and 2 are used for risks originating from gas, vapor, and mist; the codes Zone 20, 21, and 22 are designated for environments containing combustible dust. This classification is a legal standard that determines the required Equipment Protection Level (EPL) for devices. Accurate zone identification both optimizes operational costs and minimizes occupational safety risks.
In addition to ATEX certification, some projects may also require the IECEx Certification System (International Electrotechnical Commission Explosive Atmospheres System) certification. IECEx is an internationally recognized conformity assessment system for equipment intended for use in explosive atmospheres.
While ATEX is a European Union directive and a legal requirement within the European market, IECEx is a globally accepted certification system, widely preferred in regions such as the Middle East, Asia, and Australia.
From a technical perspective, both ATEX and IECEx are based on similar standards (e.g., the EN/IEC 60079 series). However:
Therefore, while ATEX certification may be sufficient for certain projects, international tenders or critical industries such as oil & gas often prefer or require products that are certified to both ATEX and IECEx standards.
The appropriate certification should be determined based on the project location, client requirements, and application area.
