30.05.2022–02.06.2022 Hannover
This year, HANNOVER MESSE will be the world’s first major industrial trade fair and, with its focus on digitalisation and sustainability, will provide clear impetus for innovative, efficient production and climate protection. Due to the high capacity utilisation of the exhibition grounds in Hannover with numerous events in early summer, the world’s leading industrial trade fair has to be shortened to four days this year.
Visit us at the NRW State Community Stand in Hall 11.

03.11.2021–04.11.2021 Madrid
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.

II 2D Ex tb IIIC T80°C Db
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.

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.

Lumiglas products are ideal for observing processes in pressure and vacuum vessels, tanks, reactors, silos, filters and other apparatus.

This LIGHT is the world’s brightest sight glass luminaire: LED luminaire is four times brighter than a typical sight glass light, offering an unprecedented view of processes. Ultra-bright LED provides 3000 lumens at full brightness, four times the light output than a typical 100-Watt halogen light. The total internal reflection (TIR) lens with 23-degree beam angle, is ideal for vessel illumination through a sight glass with maximum light output and less than 5% loss of light output. The light is capable of continuous operation and emits cool white, 5500K color temperature, optimized for stainless steel vessels. The light is designed for cool operation equipped with temperature-based current limiting and automatic dimming; over temperature shutdown. The LEDs have a long service life and are vibration and impact resistant. No heat radiation is directed into the process vessel (cold light output). The housing is available with a mounting bracket (USL16 Light) or a sanitary clamp connection (USL36 Light)
