These were our challenges
- Unused old production hall for turbines is to become repair workshop for electric motors
- A hall with 800m² and a height of 7m
- Uninsulated concrete floor, beautiful old steel construction all around, in between bricked out to 1,5m height (uninsulated) and high old windows
- Roof also made of concrete between the steel structure
- Hall in this condition is mathematically not to heat
- Requirement: Employees stand at the workbenches during their work and should be comfortable there. Additional high load on the floor when a heavy electric motor is driven into the hall by truck
Our solution:
It is essential that the surfaces relevant to the employees (floor area) are brought to the correct temperature. Directly on the old concrete floor, the egger registers, iron mats are placed over it (lower and upper probation) and concreted with 10-12cm concrete. So new concrete slab on old concrete slab.
In the area by the workbenches where the employees are located, the height is leveled with padded wood instead of concrete. The upholstery timbers are insulated to 2cm. At the height of this 2cm and between the upholstery wood come the tempering registers and above them a strap wood floor (so tempered in drywall method).
3 distributors supply the 30 circuits with a VL temperature between 28°C and 30°C. This is provided by a newly installed NUR 20kW heat exchanger supplied by the existing district heating.
The result:
There are no more cold surfaces and the employees therefore always have a pleasant temperature in the work area.
For the employees there is an additional 100m² office, a changing room and a seminar room available, which are also equipped with egger feel-good climate (floor and additionally wall temperature control).
