System benefits

  1. High flexibility

    Our extraction and filtration systems can be used flexibly. This lets you choose, for instance, between mobile and/or stationary solutions, integrated systems, or specialized ventilation solutions. If necessary, the optimal application can be configured by ULT experts on-site.

  2. Modular construction

    Modularity is the basis for the effective use of ULT ventilation solutions. This allows You to react flexibly to changing pollutant or processing scenarios and always exploit the full potential of the systems.

  3. Long filter time

    The long performance life of the filter elements in our systems reduces maintenance and material costs in the medium and long term. In addition, the downtimes for necessary filter module changes or system cleaning are significantly reduced.

  4. Based on R&D

    Research and development (R&D) has highest importance at ULT. Many projects with well-known partners and institutes have been resulted in new approaches for ventilation systems, which are often transferred to series products or quickly and easily adapted to customer-specific projects.

  5. Individual system design

    If necessary, our extraction systems can be structurally adapted to your individual pollutant and workplace situation. This applies to the selection of the ideal filtration technology, questions of fire and explosion protection, the selection of system materials and special solutions for capturing air pollutants.

  6. Ideal filtration technology

    The utilization of the most sensible filtration technology ensures a long filter service life and, consequently, reduces maintenance and spare parts costs. ULT always offers You the ideal solution for your specific pollutant technology in order to achieve the best possible filtration results.
