  • 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.

Ex­plo­sion Pro­tec­tion

DEKRA clearly explains the topic of “explosion protection” in a video that we link to here (YouTube link).

Since 1 July 2003, EG Directive 94/9/EG and its conformity assessment procedure must be applied to equipment and protective systems intended for use in potentially explosive atmospheres operating at atmospheric pressure and temperature conditions (-20 ° C to -40 ° C) 80 ° C and total pressures from 0.8 bar to 1.1 bar absolute). As the device is understood in the scope of any electrical and non-electrical equipment that represents a potential ignition source. These include lights, cabinets or electrical sensors that can cause ignition by sparks, arcs or hot surfaces. However, the directive also includes clutches, fans, compressors or rotary valves, which may be considered as sources of ignition due to possible hot surfaces or damage due to the sparking of mutually contacting clutches, fans, compressors or rotary valves.

The requirements for devices intended for use in potentially explosive atmospheres increase from Category 3 to Cat. 2 / M2 to Category 1 / M1. While for Category 3 equipment, the manufacturer can demonstrate conformity through internal production controls, the other categories must have a notified body turned on and their identification number indicated on the Ex-label of the equipment. The devices may undergo individual tests or the conformity of the device with the EG Directive may be demonstrated, for example, by an EG type examination in conjunction with a certified quality system (in conjunction with ISO 9000) of the manufacturer. Chapter 2 of the guideline describes the possible module combinations and the annexes to the guideline describe the modules in more detail.

The second group covered by the directive is protection systems. These include, for example, flame arresters that locally limit an explosion or automatic fire extinguishing equipment. Autonomous protection systems, like devices of category 1 / M1, must be inspected by a notified body.

For devices and protective systems that are not covered by the operating conditions [temperature / pressure] within the scope of the directive, the explosion protection must be demonstrated as part of the risk assessment according to the German Industrial Safety Ordinance.

Farma Forum 2021

17.03.2021–18.03.2021 Madrid

Logo Farma Forum 2021

The Forum of the Pharmaceutical, Biopharmaceutical and Laboratory Technology Industry will celebrate it’s seventh edition in 2021. Once again, the IFEMA facilities have been selected, in particular Hall 7 of the Madrid Fair.

In recent years, Farmaforum has established itself as the most important event for the pharmaceutical industry in Spain, expanding its theme and exploiting synergies with the biotechnology and cosmetics industries through the special Biotech Forum and Cosméticaforum sections.

The Farmaforum consists of an exhibition area and an extensive programme of conferences, workshops and also offers many opportunities for networking.

2021 will also see the third edition of the Laboratory Forum, materials, instruments, equipment and methods for analysis and diagnosis in the laboratory. A complementary and parallel exhibition to Farmaforum, focusing on the new generation of any research or analysis laboratory. With the integration of the Health & Research Forum, we will introduce the world of research to our forum. The pharmaceutical, biotechnology and cosmetics industries, among other sectors, depend on advances in research to bring their products to market. Accelerating these processes to ensure quality and safety has a direct impact on the cost of a new development and is therefore of utmost importance for companies.

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.

Lumiglas means: 

Individually tailored resolution of problems; using economically attractive standard products or special designs to clients’ own specification. 

A closely woven network of agencies both in and out of the country ensures efficient customer and after sales service.

Lumiglas ensures that:

All products pass the tests laid down by DIN EN ISO 9001 and in accordance with EC guideline with new Dekra/Exam according to the ATEX Directive 2014/34 / EU for Ex certificated undertakings, a mandatory examination. Thus Lumiglas safeguards the quality that brings years of practical use.


Parallel to our core competencies, we have established a comprehensive integrated quality management system that is constantly evolving with growing demands.

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.
