Cereal monitoring software

Software CTC+

  1. Floor plan of the installation
  2. Plan view of the probes of the selected silo
  3. Information of silos, probes and sensors
  4. Thermography: thermo-graphic view of the temperatures at the selected height
  5. Current filling level status of the silo


The information history of all the sensors installed in the storage plant is stored in a database that generates graphs for a better control of your grain.

The graphs allow to visualize, for each silo and at different heights within it, the following parameters over a period of time:

  1. Temperature: allows the visualization of heating trends or cooling processes.
  2. Moisture: shows the equilibrium moisture content (EMC) helping user to prevent fermentation or hotspots.
  3. Filling level: shows the quantity of cereal stored by visualizing loading and / or unloading cycles.
  4. Ventilation: allows to control the number of hours the ventilation has been working.


All the information of the CTC + can be consulted via:

  1. Internet: from anywhere and from any mobile device
  2. SCADA / PLC: via OPC or Modbus protocols


1. ON: forces the fans to start up

2. OFF: forces the shutdown of the fans

3. AUTO: ventilation will work if all of the following conditions are met:
  • Max. conservation Temperature: if any sensor in the silo exceeds this value, it will be a ventilation condition.
  • Min. Temperature Differential: safety value that allows ventilation only when the ambient temperature is, this value, below the grain temperature.
  • Min / Max Hum (%): the relative humidity outside is between these values.
  • Time interval 1 and 2: time slots where ventillation is allowed.

4. PSYCHROMETRIC: from the equilibrium temperature and humidity conditions (EMC) of the stored grain and the environmental temperature and relative humidity, the system will ventilate according to the psychrometric charts to conserve the grain in the desired conditions:
  • Max. Conservation Temperature: maximum temperature value at which we wish to conserve the grain.
  • Hysteresis: differential value to stop / run fans. The predictive system warns the user if he wants to ventilate since there is a tendency for the grain to approach a risk zone.
  • Time interval 1 and 2: time slots where ventillation is allowed.

Thanks to the anti-condensation probe that provides the temperature and relative humidity of the air inside the silo, the system determines if condensation will occur, or not, in the walls of the silo. If there is a danger of condensation, the extractors will start up.
  • Temperature differential to run / stop: safety value that allows starting or stopping the extractors only when the ambient temperature is below those values.
