Wolf® LINKEX™ LED ATEX Emergency Temporary Luminaire

The Wolf LinkEx LED ATEX Emergency Lighting Luminaire is a critical safety solution designed to ensure the safe evacuation of personnel or the continuation of work in the event of a power failure in hazardous areas. Offered by IST Safety Ltd, the official distributor of Wolf, this luminaire combines all the advantages of the standard LinkEx series with an integrated emergency battery backup.

Thanks to the "LinkEx" feature, multiple units can be daisy-chained together. In the event of a power loss, the unit automatically switches to battery mode, providing up to 3 hours of continuous light. This is vital in completely dark confined spaces such as tanks, ship holds, and underground tunnels. With its high-impact resistance and IP67 rating, it is optimized for the most demanding industrial sites.

Usage Areas

Oil & Gas: Planned maintenance or emergency lighting in refineries and petrochemical plants.
Marine: Safe working and evacuation routes in ship tanks and cargo holds.
Chemical Industry: Temporary lighting of reactors and hazardous material storage areas.
Tunnel & Infrastructure: Redundant lighting systems against power failures in underground constructions.

What is ATEX Lighting?

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.

What is ATEX Zone Classification?

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.

What is IECEx Certification? How Does it Differ from ATEX?

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:

ATEX is a mandatory legal directive, whereas
IECEx is an international certification system (voluntary, but widely required)

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.
