It’s a programmed aeration controller that automatically runs your grain bin fans at the best times based on outside temperature and humidity — proactively keeping grain in condition without constant monitoring.

The system senses outdoor conditions and turns fans on and off at precise times to reach your target grain temperature and moisture. It takes the guesswork out of managing aeration.

Most competitors react after grain is already out of condition. Sentry Pac Pro™ is proactive—it prevents spoilage before it starts by maintaining optimal conditions automatically.

While it’s always good to physically check your grain, Sentry Pac Pro™ dramatically reduces the need to climb bins or rely on cables. You’ll know your grain is being protected 24/7.
