Don’t just monitor your grain. keep it in  Condition. 

Sentry Pac Pro™ uses real-time outside conditions to automatically manage aeration, helping your grain stay in ideal condition without cables, sensors, or constant checking.

Monitoring reacts.

Most grain 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™ 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™ 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.

Monitoring has its place -  but it shouldn’t be your first line of defense.

Monitoring tells you what happened.


Conditioning prevents problems from happening in the first place.

Sentry Pac Pro™ focuses on prevention first —

because the best alert is the one you never receive.

The Sentry Pac Pro™ has been proven to show returns of $77,089 on 40,000 bushels of soybeans over 5 years.

Makes you money.

"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. "
