5 CLARIFICATION STEPS FOR YOUR EX PROJECT

Here you can find out in 5 steps which special features must at least be taken into account when selecting suitable Ex luminaires. Products matched to the individual area of application mean safety, durability and economy.

Step 1: Ex area(s)

Step 1: Ex area(s)

Clarify whether your project involves one or more areas with potentially explosive atmospheres.

These areas are subject to strict requirements and measures according to EU Directive 1999/92/EC (implemented in Austria as VEXAT – Ordinance on Explosive Atmospheres) and further regulations. The Ex areas are subdivided according to defined specifications and require a special design of the emergency luminaires.

Such conditions can occur, for example, in chemical factories, cleaning plants, paint shops, refineries, mills or tank farms for flammable substances.

Step 2: Explosive substance(s) and zone(s)

Step 2: Explosive substance(s) and zone(s)

Depending on the type of flammable substances, you are confronted with different conditions, which must be taken into account when selecting Ex luminaires. A distinction is made between gas Ex areas (gas, mist, vapour), dust Ex areas (dust) and mine workings at risk of firedamp (mining). The frequency and sustained duration of a potentially explosive atmosphere determine the defined Ex zone classification according to EN 60079-10-1 and EN 60079-10-2.

The tabular representation shows the classification of flammable substances into the respective zones. The graphic below shows an example of the possible area classification of the individual Ex zones. What conditions do you have in your project?

Step 3: Temperature class(es) and max. enclosure surface temperature

Step 3: Temperature class(es) and max. enclosure surface temperature

The temperature class(es) of the units or luminaires for gas Ex areas are determined on the basis of the ignition temperature of the respective gas or vapour. The table above gives an overview.

The max. enclosure surface temperature for dust Ex areas must be specified by the operator. Which temperature class or max. enclosure surface temperature is relevant in your case?

Step 4: Relevant gas or dust substance group(s)

Step 4: Relevant gas or dust substance group(s)

Gases, vapours and dusts are divided into substance groups IIA / IIB / IIC or IIIA / IIIB / IIIC depending on their properties. The substance subgroups IIC and IIIC have the highest equipment requirements.

The tables below show an excerpt of the substances assigned. Which gas or dust substance groups are to be considered in your case?

Step 5: Environmental conditions and special features

Step 5: Environmental conditions and special features

In hazardous areas, further environmental conditions and special features must be taken into account in order to be able to select suitable Ex escape sign and emergency luminaires. Parameters that can be mentioned are the prevailing ambient temperature, the given humidity conditions and the resulting protection class, the required IK impact resistance level, UV influences due to solar radiation and chemical influences.

What are the specifics and concrete parameters to be used in your project?

INDUSTRY EX X32

Special features of our latest Ex luminaire series

 INDUSTRY EX X32

High detection distance

The INDUSTRY Ex X32 has a detection range of 32 metres and is the ideal solution for long aisles in hazardous areas.

Simple mounting

The definable cable entries are drilled and installed at the factory. The luminaire itself is fixed from the outside using mounting brackets. This simplifies installation on site.

Many variants

The INDUSTRY Ex X32 is available in several monitoring types including single battery. In addition, the FSU variants enable directionally variable escape routing (adaptive).

CONCEPT EX

Special features of our proven Ex luminaire series

 CONCEPT EX

High-quality materials

The housing of copperfree aluminium combined with high-temperature resistant borosilicate glass tubing makes the CONCEPT Ex so safe.

Combined benefits

With the CONCEPT Ex RZ1 plus/duo, an additional emergency luminaire for simultaneous illumination of the escape route is available in addition to the escape route marking.

Proven luminaire series

The CONCEPT Ex has proven itself: more than 1,000 units sold in over 100 implemented projects speak for themselves.

ZONING OF THE EX-AREAS

The CONCEPT Ex and the INDUSTRY Ex X32 are suitable for use in gas Ex areas of zone 2, as well as for dust Ex areas of zone 22 and are certified accordingly. The CONCEPT Ex is also suitable for use in gas Ex areas of zone 1, as well as for dust Ex areas of zone 21.

The zone classification depends on the frequency and duration of the occurrence of a potentially explosive atmosphere and is regulated by standards.

The certified device category or device protection level confirms that the luminaire is suitable for use in the respective Ex zones. Depending on the existing Ex zone, at least one corresponding device category or device protection level of the luminaire used must be available.

Our solutions for potentially explosive atmospheres are ATEX-certified – this certification stands for high demands on the quality of our products and the associated quality assurance. The ATEX officers in our company make sure that these standards are constantly met and are available as internal contacts. Training courses ensure knowledge of the Ex area within the company and make your din contact person a knowledge carrier for questions about emergency lighting in the Ex area.

With our products, we assume sole responsibility for compliance with the manufacturer/product guidelines. Please note the operator's obligations in potentially explosive areas, as well as the liability disclaimer in the imprint.
