With the ACD 400.1 Ex extraction and filter system, ULT presents a new solution for removing atmospheres with flammable components. The system, equipped with an explosion-proof fan in accordance with ATEX Ex II 2G T3, was developed for the extraction and filtration of dry, flammable and non-flammable gases and vapours in concentrations of up to 20% of the lower explosion limit. It is a modular, two-stage storage filter unit consisting of an M5 dust pre-filter and two adsorption filter modules (activated carbon). To prevent the ignition of flammable gases and vapours in the filter, the activated carbon filter elements and downstream components - such as the ATEX-compliant fan and the ATEX-compliant motor - are earthed and designed without ignition sources. In addition to its properties as an Ex device, the ‘ACD 400.1 Ex’ offers further user benefits such as extremely quiet operation, low energy consumption and high flexibility with regard to changing workstations or emission types. The filter cassettes are electrically conductive with a potential equalisation connection and also offer…

How manufacturing companies can sustainably reduce their energy costs through clever and forward-looking system design The energy crisis is the great spectre for the European economy. Rising electricity and gas costs coupled with rising prices in the supply chain are pushing many a company to the brink of survival. However, as we all know, every crisis also offers opportunities - especially regarding the energy-optimized use of production technology and accessories. The utilization of air pollution control systems has become standard for the majority of manufacturing companies. On the one hand, there is a company requirement to protect employees, manufacturing equipment and products from the influence of airborne pollutants and emissions - and on the other hand, there are legal requirements and regulations. However, in times when the demand for energy savings is increasing, the use of extraction and filter systems seems to be more of a necessary evil. Yet this is precisely where the opportunity lies to save significant amounts of money over a longer period. The approach to saving…

On April 3, 2023, ULT planted mora than 100 trees in the UNESCO biosphere reserve of the Oberlausitz heath and pond landscape. This action resulted from a promise made at the 7th ULT Symposium in May 2022. The ULT Symposium in Löbau/Germany was designed as a climate-neutral event. An important part of that goal was the ULT’s commitment to plant a tree for each attendee at the event. Consequently, on April 3rd, a total of 120 silver firs were planted as seedlings. Alexander Jakschik and Dr. Stefan Jakschik, CEO of ULT AG, are happy about the campaign: ”As a company, we have set ourselves an internal goal to achieve climate neutrality in 2030. This tree planting is an important campaign for us, because we want to contribute to climate protection, and additionally want to send a message to other companies. Climate protection concerns us all, and manufacturing companies in particular must set an example.” The ”Upper Lusatian heath and pond landscape biosphere reserve” was chosen as the site for the tree planting, because this is where the Free State of Saxony’s forest conversion program for climate-stable forests is lived and implemented.

ULT has developed a dedicated version of the LAS 800 extraction system free of ignition sources to increase explosion and fire protection during laser dust extraction. The all-new LAS 800 Ex was specially designed because ever finer combustible dusts are produced in laser processing due to higher input energies or shorter laser pulses. Therefore, the explosive potential increases with the degree of fineness in the dust. The ignition source-free device is an externally tested and confirmed solution that safely extracts the finest laser dusts at relatively low investment costs, utilizing H14 HEPA to ensure a separation degree of over 99.995%. Both the suitability for extracting explosive dusts (at the IBExU Institute for Safety Technology, Freiberg/Germany) and the filtration efficiency of the filters (at the Institute for Ventilation and Refrigeration Technology ILK, Dresden/Germany) were assessed. The ignition source-free design of the device ensures that the potential for explosions is eliminated when the LAS 800 Ex is used as intended, and expensive structural explosion protection can therefore be dispensed with. The LAS 800…
