Fan Control System – Automated Grain Pile Tarp Management
The Comco Fan Control System is an intelligent automation solution for managing grain pile fans. It helps maintain tarp integrity, reduce power consumption, prevent grain shrinkage, and support remote access – all while minimizing manual intervention. Designed for rugged agricultural environments, the system optimizes fan usage based on real-time wind conditions and operational modes.
System Overview
This automated controller regulates fans used to keep tarps secured on outdoor grain piles. It monitors wind speed and activates fans accordingly – increasing or decreasing airflow to ensure the tarp stays in place, protecting stored grain from spoilage while minimizing unnecessary energy usage.
Key Benefits

Save Energy Costs
Fans run only when needed based on wind speed.

Reduce Grain Shrinkage
Prevents excessive moisture loss during storage.

Protect Against Weather
Keeps tarps secure against wind, rain or snow.

Remote Access
Access from anywhere with internet for remote monitoring and support
Key Features and Capabilities
– Storage Mode: Adjusts fans automatically based on wind speed using configurable thresholds.
– Grain Conditioning Mode: Runs all fans for a set time to assist drying/cooling, then reverts to storage mode.
– Manual Mode: Operators can control individual fans directly via the HMI.
– Wind-Speed Based Control: Fans activate progressively (e.g., Fan 1 at 5 mph, Fan 2 at 10 mph, etc.).
– Remote Monitoring: View status, alarms, fan run time, and max wind speed from any location.
– Configurable Setup: Customize number of fans, delays, and generator interlocks.

Ideal Applications
The Comco Fan Control System can be used for outdoor grain pile storage requiring tarp protection.
