ATEX Light Fitting | Lighting for Zone 21, 22 and 2

Change of Lighting Direction Through Lenses

The Ex OptiLine fixture allows for the use of lenses that can modify the lamp’s direction of illumination. This is yet another feature that can significantly simplify the installation process, leading to reduced costs. But how does it work?

For most fixtures, if you need to illuminate specific areas, like a valve, fire extinguisher, or switch, you’d typically need to use special mounts that direct the entire fixture towards the target. This can unnecessarily complicate the installation and often increase its cost. The ATEX OptiLine fixture doesn’t require any additional mounting accessories. You install it in a conventional manner in an easily accessible location with the appropriate lens that directs the light. You have a choice of up to 22 different types of lenses.

Use as a High-Bay Fixture

A special focusing lens concentrates the light beam, allowing for mounting the fixtures at increased heights. In many cases, this enables the use of OptiLine fixtures as High-Bay lamps. This, in turn, allows for the use of a single type of fixture in a given space without the need for special structures to lower the mounting point. All of this translates to reduced investment and maintenance costs.

Customizable Emergency Light Output

Each fixture can have a different light output in emergency mode. This solution increases flexibility during the design of the lighting installation, which leads to reduced installation costs.

For instance, instead of adjusting the lighting level of a particular area through expensive control systems or the height of the fixture installation, it is sufficient to set the light output power for each fixture individually.

Connect Fixtures as You Need and Save

Many fixtures have significant limitations regarding the number and size of cable glands that can be mounted on their body. The most expensive in terms of installation are fixtures with a single gland of one size or even with a factory-outlet power cable.

Consider a situation where you need to install dozens of fixtures along a wall. If the fixture has only one cable gland, it is necessary to use ATEX junction boxes, which are typically several times more expensive than the standard solution. Furthermore, this approach requires a higher consumption of power cables and cable trays.

However, if the fixture has two cable glands on one side, it’s possible to route the power cable directly from one lamp to the next without the need for junction boxes. This approach also requires less cable and cable trays. All of this results in tangible savings. There are many such scenarios in the industry where additional cable glands lead to savings.

That’s why the Ex OptiLine fixture allows for the installation of up to 4 cable glands M20 or M25 (two on each side).

Larger Cable Gland in the Fixture = More Freedom in Cable Selection

The ability to use M25 cable glands in the OptiLine explosion-proof fixture allows the use of cables with larger cross-sections. This provides the freedom to choose their manufacturer and the opportunity to use thicker non-flammable cables.

A gland with a larger diameter also allows for the use of cables with larger cross-sections of wires to reduce voltage drops over length. This is especially important for emergency lighting fixtures, which are expected to have cables that can operate at temperatures above 600°C.

Quick and Safe Installation of Ex Fixtures

A thoughtful design without loose components is another advantage of explosion-proof area fixtures. How does it work? The fixture’s diffuser and the internal mounting plate, on which the LED module is located, are hinged.

Opening the diffuserinvolves detaching the metal clasps on one side of the lamp (clasps on the other side act as hinges, eliminating the risk of the diffuser falling). Since it’s an ATEX-certified fixture, regulations require this action to need a tool. To keep it as simple as possible, we designed the clasps to be opened with a single screwdriver motion.

Importantly, if needed, the diffuser can be completely detached from the body.

To open the mounting plate, just unscrew two easily accessible screws. With their specially designed heads, you can do this by hand or with a screwdriver. Importantly, we’ve applied so-called “captive screws” here, meaning that once unscrewed, they remain in the mounting plate. Such an open fixture provides convenient access to electrical components, including cable connectors, for quick power connection.

The assurance that no part of the lamp will fall during installation is not just a convenience but also a safety feature. A lost screw that accidentally falls into a process installation can not only contaminate the product but also be a cause of equipment malfunction or, in extreme cases, be a source of mechanical sparks, which can contribute to the ignition of an explosive atmosphere.

LED Fixtures for Explosion-Prone Areas

The explosion-proof fixtures of the OptiLine series are certified with ATEX and IECEx, allowing their use in Zones 21, 22 (dust) as well as Zone 2 (gases, vapors of flammable liquids) explosion hazard areas.

Why to use an ATEX / IECEx OptiLine luminaires

ATEX / IECEx OptiLine luminaires should be used in environments with potentially explosive atmospheres because they are specifically designed and certified to ensure safety and compliance with stringent regulations. These luminaires provide energy-efficient lighting, durability against challenging conditions, and versatility for both basic and emergency lighting needs. By using them, organizations can prioritize the safety of their workers, meet regulatory requirements, and benefit from reliable and efficient lighting solutions in hazardous locations.
