Understanding What PAC and PRO Mean with the Sentry Pac Pro™

When it comes to aeration and managing grain storage, precise control and reliability are the benchmark of quality. The exclusive PROACTIVE features are what allow the Sentry Pac Pro™ to surpass that benchmark. In this article, I’ll walk you through what PAC and PRO mean, how the Sentry Pac Pro™ works, and why it’s a game-changer in aeration control.

What is the Sentry Pac Pro™?

Put simply, the PAC runs your fans automatically, never letting your grain go out of condition.

This isn’t just about turning on fans and hoping for the best; it’s about precise, proactive control, and automation.

The Sentry Pac Pro™ is designed to automatically control the airflow to your grain bins based on a programmed airflow budget and target ambient conditions. It uses pre-programmed calculations to constantly keep your grain in condition. By monitoring the outside conditions, the PAC never allows fronts of air to be pushed through your grain. Through its revolutionary proactive technology, the Sentry Pac Pro™ separates itself from all other grain management systems.

Why Programmed Aeration Matters

You might wonder why this level of control is important. Grain storage isn’t just about keeping grain dry; it’s about maintaining the quality and preventing spoilage or insect infestations. Aeration helps by cooling the grain and reducing moisture, both of which are critical to preserving grain integrity over time.

Traditional aeration methods often rely on manual timers or cables in the bin that

only run the fans after they detect a problem. These antiquated methods can lead to over-aeration, hot spots, or under-aeration, risking spoilage. The Sentry Pac Pro™ eliminates these issues by using pre-programmed calculations based on your specific grain and storage goals.

Breaking Down Programmed Aeration Control

When I say “Programmed Aeration Controller,” what I mean is that the controller allows you to set a specific airflow budget and target moisture content for your grain. Let’s unpack that a little more.

• Airflow Budget: This is the amount of time you want the fans to run each day. For most users, the default budget is around four hours. This means the fans will run for a maximum of four hours daily if the target ambient conditions are met.

• Target Moisture Content (TMC): Rather than programming the controller based on the grain's condition when it enters the bin, you specify a target moisture content for the grain to reach before delivery. For example, if you want your grain to be delivered at 15% moisture, you would enter that value into the controller.

Once you’ve set these parameters into the Sentry Pac Pro™ according to your needs, all you do is set the controller to “storage” mode and push “auto run.” From there, the controller takes over, running the fans as needed to maintain the specified conditions.

That’s it!—there’s no more manual adjusting or monitoring required.

the “Pro” Features

The “PRO” in Sentry Pac Pro™ stands for the Proven Proactive Protection that it offers.

• PROVEN: With 40+ years of real world results, the PAC will deliver reliable results year after year.

• PROACTIVE: By only running the fans at the optimum ambient conditions, the PAC never lets your grain get out of condition in the first place.

• PROTECTION: Standing guard as a sentry, the Sentry Pac Pro™ is constantly protecting your grain for your peace of mind.

Connectivity

The Sentry Pac Pro™ now comes standard with a mobile app, making it easier than ever to monitor and adjust your aeration system from anywhere. With the Sentry Pac Pro™ app, you have peace of mind delivered right to your hand.

How to Set Up the Sentry Pac Pro™ for Your Grain Storage

Setting up the Sentry Pac Pro™ is straightforward:

1. Determine Your Target Grain Conditions: This is simple... At what moisture do you want to deliver your grain? For instance, if I want to deliver my corn at 15% moisture, that’s the target I’ll select.

2. Set Your Airflow Budget: Also very simple, the default is set for four hours per day, but you can adjust this as needed.

3. Program the Controller: Enter these values into the Pac Pro™ and set it to storage mode.

4. Activate Auto Run: Push the auto run button and let the controller manage the rest.

Once it’s running, you can relax knowing your grain is being aerated efficiently and effectively. Yes, it is really that easy.

Benefits of Using the Sentry Pac Pro™

There are several advantages to using the Sentry Pac Pro™:

• Precision Control: Set exact parameters for airflow and target moisture content, ensuring optimal storage.

• Energy Efficiency: Fans only run when needed, saving electricity and reducing costs.

• Remote Monitoring: Use the app to keep an eye on your Pac from anywhere.

• Peace of Mind: Automated control means less manual intervention and worry.

The Future of Grain Aeration

Technology is transforming agriculture, and grain storage is no exception. The Sentry Pac Pro™ represents a step forward in how we manage stored grain—bringing together years of precision programming, connectivity, and proactive protection into one easy-to-use system.

By focusing on the conditions you want to deliver grain at, rather than just reacting to what’s currently in the bin, the Pac Pro™ helps ensure your grain maintains its quality throughout storage. Whether you’re a commercial operator or a farmer managing your own bins, this kind of control makes a all the difference.

Conclusion

To sum it up, the Sentry Pac Pro™ is a programmed aeration controller that takes the complexity out of grain aeration. The “Pac” refers to the programmed aeration control system, and the “Pro” highlights the added connectivity and proactive protection features that give you remote control and peace of mind.

With simple programming based on your target moisture content and airflow budget, and an easy-to-use app, the Pac Pro™ is designed to help you store grain smarter, safer, and more efficiently. If you want to take the guesswork out of aeration and protect your investment, this system is the only one to do exactly what your grain needs.

Remember, programmed aeration control isn’t just about running fans—it’s about delivering the right airflow at the right time to maintain optimal grain conditions. That’s what the Sentry Pac Pro™ is built to do.
