Sesotec's path to the future. #NewLevelFactory

News (Status March 2025)

The Sesotec #NewLevelFactory stands for innovation and cutting-edge technology – a project setting new standards for energy-efficient and future-proof construction. Big things are happening on-site: Geothermal drilling for sustainable heating is in full swing!

Heating power in action!
We’re drilling 21 holes plus an additional one for temperature monitoring – each reaching a depth of 140 meters. Despite the frozen ground: The harder the material, the better!

Impressive dimensions
The total drilling length amounts to 2,940 meters – roughly the same as the tunnel length of a small mining operation!

Right on schedule
With 3.5 drillings per week, all holes will be completed by the end of week 12. Supply lines are already being installed during the drilling process. From week 13, the boreholes will be filled and connected to the building.

The grand finale
From week 30, our heating will run on geothermal energy!

The new building of Sesotec is an excellent example of resource conservation par excellence. Through a minimalist architectural design that interferes as little as possible with the natural terrain, it harmonizes with the surrounding landscape. In addition, the building features an innovative energy management concept based on a combination of photovoltaic and geothermal energy, completely avoiding the use of fossil fuels.  

Through these measures, the new building makes a significant contribution to the energy transition and climate protection. In addition, a water recovery system is installed, which further increases the sustainability of the building and significantly reduces water consumption.

  • Planned size of the hall in square metres: Construction phase 1 with 12,500m²
  • Maximum production capacity that can be achieved in the hall: Volume of 140 million euros
  • Number of employees who will work there: 190 at the beginning of 2025, 230 at the beginning of 2027
  • Departments that will move into the new building: Manufacturing and Assembly Product inspection, engineering, planning, work preparation, Disposition, Service

Equipment features and functions of the production hall, such as special machines or technological equipment:

  • Complete Metal processing Laser - folding - welding - surface treatment
  • 21 assembly lines for individual / small batches incl. Prototyping and acceptance of explosion-proof systems

  • Construction method: Steel-concrete or wood-concrete hybrid
  • Building materials used:
    • Glass fronts let a lot of light into production halls and offices. The view out of the assembly halls into nature is unobstructed.
    • Wood for a pleasant indoor climate and acoustics
  • Facade cladding with so-called "meander sheet", which protects against glimpses and direct sunlight

  • Start of construction: Autumn 2023
  • Completion of construction phase 1: May 2025
  • Planned start of production: July 2025
  • The implementation of all possible further expansion stages is expected to last until the year 2030

Estimated Total cost of the project: tens of millions of euros

One of the most important points was to use as few terrain resources as possible. The building integrates into the landscape and the existing conditions are interfered with as little as possible. In addition, innovative energy management was a particular concern during the planning process. With the use of geothermal energy and photovoltaics without fossil fuels, this issue and the ecological footprint are solved in a way that is generation-friendly.

Comprehensive Land-use plan incl. geological expertise, environmental reports, flood calculations and noise protection

As far as the existing location in Saunstein is concerned, there are already plans for modernisation, which are also being implemented step by step.
