The SPS control system

  • With the working mode according to return water temperature, the fan speed will be controlled automatically in order to maintain the desired return temperature to the heating source.
  • The working mode according to air temperature is suitable for the drying of seed, grain and other temperature-sensitive bulk solids.
  • The working mode according to pressure differential avoids unnecessary high revolution rates of the fan and therefore helps save electricity.
  • The working mode according to maintenance of flow temperature permits to a superior district heating network that desired level of flow temperature is maintained and that only the remaining heat energy is used for drying.


Extension of the control system with touch panel

  • Visualisation of all drying data.
  • Electrical regulation of valves for automatic drying, with timer operation or optionally according to final moisture content.
  • Access possibilities for web-server.
