The entire plant in Affoltern am Albis consists of 2 round wooden silos on a cubic steel substructure. The plant also has a brine mixing plant with storage tank. The silos each have a capacity of 400 m3. A mobile return conveyor system was supplied for emptying the vehicles at the end of winter.

The façade has been treated three times and is made of spruce wood. The brine generator is filled with de-icing salt directly from the silo using a discharge screw conveyor. The storage tank of the brine system has a volume of 40m3.
