Monitoring reacts.
Conditioning prevents.
Most grain monitoring systems rely on sensors and cables inside the bin to tell you when something has already gone wrong.

Sentry Pac Pro™ works differently.
Instead of monitoring problems after they start, Sentry Pac Pro™ is a grain aeration system that uses outside temperature and humidity conditions to actively maintain the ideal environment inside the bin — keeping grain in condition from the moment it’s stored.
✅ No cables.
✅ No probes.
✅ No waiting for alerts that mean damage has already begun.
Just proactive conditioning that protects your grain every day.

why no cables?
As farmers, we know how frustrating it is to deal with cables inside your grain bins. What we love about Sentry Pac Pro™ is that it doesn’t require any internal monitoring hardware to do its job.
By leveraging outside air conditions — the same principles farmers have trusted for generations — Sentry Pac Pro™ automatically runs fans at the right times to maintain optimal grain condition.
Sentry Pac Pro™ is a grain bin aeration system that has protected millions of bushels each year for thousands of farmers without the use of any cables.
If you want to add monitoring, you can. But you don’t need it to protect your grain.
" After we ran the Sentry Pac Pro™ first season, we went back and compared our previous seasons without it on our electrical cost and didn't realize how much we were saving with it. I bet our savings is probably 60-70% of what it was before we purchased the system. So we purchased another system and put on our second grain site. What I like about it, you can set your run time on it, how many hours a day you want it to run, and you can set your moisture where you want your grain to come out at. And it usually comes out just within a half a point of where you have it set. We put fairly wet corn in the bins - up to 22, 23 moisture corn in some bins and it's coming out now around 16, 17 moisture. We don't have the initial drying cost of using natural gas or something like that. It's just all air dry. Because before we never knew, "Well, should we run fans today or should we not run them today?" We was always looking at humidity, temperature, trying to figure it out. Now it does all the calculation for us and runs it at the best time it needs to in the 24-hour period."

"I've used it for approximately 15 to 18 years. You just have to believe in it, trust it, let it do its job. Once you've filled it, set your moisture and that's what it will come out at at the end. It would be stored for six months, and it would come out good quality. "
John Wenzel from Central Michigan
"My dealer recommended that I put in a Sentry Pac and, it has been by far the best investment I've ever made on the farm. I can sleep at night. Fans come on when they need to, and they don't come on when they don't need to come on. It's just preventing all those problems in that. It's a wonderful wonderful product, I would say if you have any amount of storage, grain storage at all, of any size, really, it's a no-brainer for the investment that you're gonna make. "
