  • The Lumistar luminaire USL 07 LED-Ex captures areas of application that were so far unsuitable for illumination in potentially explosive areas.
  • Suitable for ambient temperatures of +60 °C. Effective measures  against corrosion ensure universal application possibilities.
  • The large light emission and the optimally designed screwed glass opening make the luminaire perfect for the illumination of vessels, tanks, agitators, silos and other, generally closed, containers and reactors and also in visual flow indicators in potentially explosive environments. Suitable for use in the food processing industry.
  • Protection class: Dust-tight and water jet-proof, IP 65 and IP 67 acc. to DIN EN
    60529/DIN VDE 0470, part 1.
  • This sight glass luminaire is designed for universal applications in potentially explosive
    operating areas and is ideal either in combined sight and light ports (single-flange
    version) or for separate ports (two-flange version).

Long service life and extremely robust construction:

Due to the long-life LED there is no heat radiation from the light emission. The robust
construction of the Lumistar USL 07 LED-Ex is especially designed for use on
vibrating or oscillating tanks.

Always reliable in use:

Downtimes in production as well as maintenance cause huge costs.
With the refitting to Lumistar LED luminaires, service cycles are more than doubled.
Depending on the environment, our customers can expect several years of
maintenance-free operation.

Lumiglas – the observation of process operations taking place 

inside pressure and vacuum vessels, tanks, reactors, silo units, filters and other plant demands perfect illumination and unhindered visual check. 

that is what lumiglas offers.

Lumiglas stands for sight and light ; for ideal visual control.

These inspections are carried out either by the process operative directly on the spot or without the need to access the plant, by means of the Lumiglas VISULEX Ex camera system. The combination of light and sight glass, created by Papenmeier- the first of many Lumiglas patents- is the ideal low cost solution for the user: the additional cut-out for a second sight port in the case of separate ports is avoided.

More security- less cost!

Lumiglas is internationally renowned and used by leading companies worldwide, particularly in explosion hazardous areas of the chemical, bio and pharmaceutical industries: mineral oil refining as well as foodstuffs and beverage industries, nucleur power plant, machine construction, electro industry, water treatment and shipbuilding.

Explosion protection

As of July 2003, organizations in EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere.

There are two ATEX directives (one for the manufacturer and one for the user of the equipment):

  • the ATEX 95 equipment directive 94/9/EC, Equipment and protective systems intended for use in potentially explosive atmospheres;
  • the ATEX 137 workplace directive 99/92/EC, Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.

The ATEX 94/9/EU that is dedicated to the manufacturer has changed. Always applicable up to 19 April 2016 the ATEX 94/9/EC will be removed and replaced by a new directive.

This new ATEX directive was published on Saturday 29 March 2014, under the new reference : Directive 2014/34/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to equipment and protective systems intended for use in potentially explosive atmospheres (recast) Text with EEA relevance – Official Journal of the European Union L 96 from 29/03/2014.

This new ATEX directive 2014/34/EU will be mandatory for manufacturer on 20 April 2016 as is stated in article 44 of the directive.

Promised for a long time, this new ATEX directive has been published together with 8 other directives in the frame of NEW LEGISLATIVE FRAMEWORK (NLF) ALIGNMENT PACKAGE (Implementation of the Goods Package). It was the subject of a “COMMUNICATION FROM THE COMMISSION TO THE EUROPEAN PARLIAMENT AND THE COUNCIL” for the Alignment of ten technical harmonisation directives to Decision No 768/2008/EC of the European Parliament and of the Council of 9 July 2008 on a common framework for the marketing of products, in Brussels, 21.11.2011 under reference COM(2011) 763 final.

Lumistar Luminaire REL 01/REL 01-Ex, Stainless Steel – Rectangular Light Series

Luminaires (Ex)

Product Picture: Lumistar Luminaire REL 01-Ex, stainless steel

ex II 2G Ex ia C T4/T5/T6 – intrinsically safe
ex I M2 Ex ia I Mb

Also comes in non-Ex

Lumiglas supply this stainless glass luminaire in two versions for use in potentially explosive environments and for normal operating conditions.

Designed for use with rectangular / longitudinal sight glass units; installed in bioreactors, laboratory mixers, filters and, generally, all normally closed tanks, agitators, separators, pipelines and other vessels operated in explosion-hazardous environments (Zones 1 and 2) as well as in non-hazardous work areas.

Suitable for use in the food processing sector

The Lumistar luminaire REL 01/REL 01-Ex is a complete unit ready for fitting. It is attached directly to the cover flange of a rectangular sight glass unit by means of two screws.

The REL01 unit has been designed to fit snugly into the side of rectangular / longitudinal sightglasses, length = 250 mm
The Luminaire REL 01 comes ready for fitting, 2 screws enable it to be bolted straight onto the cover flange of the longitudinal sightglass.

Compact design, high light output, low energy consumption:

21 special LEDs ensure dazzle-free illumination.

Together with the corresponding electronic switchgear, these LED are resin-cast into the stainless steel housing which is then secured to the rectangular fitting.

The service life of this luminaire is virtually unlimited; even if one of the diodes fails after a long period of operation, the remaining LED still provide more than enough light intensity.

Type of protection: Provided the luminaire has been properly installed, it is dust- and splash-proof, IP 65  acc. to DIN EN 60529/DIN VDE 0470 Part 1

Operating Voltage / Power: 24V / 2W

Where the Luminaire is to be used in explosion hazardous areas, connection must be to an intrinsically safe power supply circuit.
