The plant is used for solution annealing of components made of aluminum alloys in a molten salt bath. The plant is installed at ground level, has 4 separately movable lids and is fed with the material to be treated from above via a crane system.

The temperature control of the molten salt is optimized in such a way that the temperature uniformity in the working chamber of class 1, according to AMS2750E, is achieved with a variation of +/- 3 K (°C).
