The Silo Temperature and Humidity Control System is an intelligent monitoring and management solution designed specifically for grain storage silos.
This system continuously monitors internal grain conditions by collecting real-time temperature and humidity data from multiple distributed sensing points installed inside the silo.
Unlike traditional temperature-only monitoring systems, this integrated solution provides dual-parameter analysis (temperature + humidity), allowing more accurate evaluation of grain condition and early detection of potential storage risks.

The system effectively helps prevent:
- Grain hot spots
- Condensation formation
- Mold growth
- Quality deterioration
- Moisture migration inside grain bulk
By connecting with ventilation fans or aeration systems, the control unit can trigger automatic alarms and intelligent ventilation control when preset thresholds are exceeded.
This solution is widely used in:
- Steel grain silos
- Concrete silos
- Large grain storage terminals
- Government reserve storage facilities
- Commercial grain processing plants
The system supports RS485 / MODBUS communication and can be integrated with host computer software and cloud-based monitoring platforms.
Factory direct supply from China. OEM and project customization available.
