Rotary shaft seals: Masters of rotation
04.03.2025
Energy consumption in systems with rotating components is significant. Trelleborg Sealing Solutions has achieved a reduction in this consumption of more than 20% with its latest generation of Stefa® rotary shaft seals (RWDR). These RWDRs also withstand the increased speeds and accelerations generated by modern electric motors.
Ethernet-APL: Last chance for digital field communication
04.02.2025
Do you remember the sound of the internet? Some of you may nostalgically remember the sound of their 56k dial-up modem. And at the same time, you probably think “good old times, but even better that they are gone”. In times of high-speed internet at home and 5G mobile coverage, date rates in the kbit range seem rather outdated.
Water Treatment for Hydrogen Production through Electrolysis
20.01.2025
Water treatment plays a central role in hydrogen production through electrolysis. The quality of the water used is crucial for the efficiency and lifespan of the electrolyzer. Impurities such as salts, metals, or organic substances can damage the electrodes and membranes in electrolyzers.
PFAS: A decisive factor with an uncertain future
08.01.2025
Just as the deadly button mushroom should not be confused with edible mushrooms and the poisonous honeysuckle should not be confused with the nutritious elderberry, the plant world is rich in species that require different assessments. Some are poisonous, others are a source of vitamins and health.
New machinery regulation requires stricter cybersecurity standards
16.12.2024
As digitalization progresses, machines and devices are integrating more and more software components. The EU has addressed this in its new Machinery Regulation (MDR), which will replace the previous Machinery Directive after a transitional period.
H₂-ready Power Plants: The Key to Climate-Neutral Energy Supply
02.12.2024
Germany aims to become a climate-neutral industrial nation by 2045. This energy transition brings significant challenges. The entire energy system must be transformed to reduce CO2 emissions.

The 10 commandments of attack detection
18.11.2024
In the jungle of standards and legislation, the term “attack detection systems” is often used. References are made to the “state of the art”, to the BSI's basic protection compendium or to vaguely formulated objectives for measures. As a result, I come across many companies that are confused and faced with a mountain of opaque tasks.

Ice-cold precision: seals for extreme temperatures in cryogenics
04.11.2024
Cryogenics, which deals with the handling and application of extremely low temperatures, poses special challenges for the sealing systems used. Unlike conventional seals, which are designed for use at room or moderate operating temperatures, seals for cryogenics must withstand extreme temperature ranges without losing their sealing or mechanical properties.

Valve test benches: Safety first
21.10.2024
The testing of valves is of central importance for the safety and efficiency of industrial plants. Particularly in sectors such as the chemical industry, power generation and water management, valves must be regularly checked for functionality in order to recognise and reduce potential risks at an early stage.
AI in industrial work: perspectives and design options
07.10.2024
In the new report ‘Artificial intelligence and industrial work - perspectives and design options’ by the Industry 4.0 Research Advisory Board, the Fraunhofer Institute for Mechatronics Design Technology IEM and the Fraunhofer Institute for Material Flow and Logistics IML examine the integration of artificial intelligence into industrial work.
