Two belt dryers with a yearly capacity of 80.000 tons were installed at a plant of an energy provider to increase the capacity. Besides the two new belt dryers, the control technology comprised the corresponding air circulation system, the conveyance of the wet and dry sludge as well as the exhaust air treatment. The energy supply of the plant is monitored fully automatically.

If one power supply fails, the network is completely switched to the redundantly planned second supply. The central control system was connected to the existing control system via a bus system.
Therefore, the plant can be completely controlled from the remote control room of the energy provider.
