PREVENTS SPOILAGE
This began in 1974 on an Iowa farm. Since the introduction of the first Sentry PAC (Programmed Aeration Controller) in 1983 , Sentry Pac Pro™ continues to set the standard for advances in grain care.
The Sentry Pac Pro™ controls moisture content (MC) and prevents spoilage in grain with an adaptive proactive method of aeration.
The Sentry Pac Pro™ prevents grain spoilage by using proactive programmed aeration control to manage temperature and moisture levels in storage bins. Unlike traditional aeration systems that rely on manual adjustments or reactive temperature monitoring, Sentry Pac Pro™ uses advanced algorithms to anticipate and prevent spoilage before it starts.
Here’s how it works:
Automated Aeration Control – The system continuously monitors real-time weather and adjusts airflow automatically to maintain optimal storage conditions.
Prevents Hot Spots – By evenly distributing air, it reduces temperature variations that can lead to mold growth and insect infestations.
Moisture Management – It ensures that excess moisture is removed before it can cause grain spoilage.
Energy Efficiency – Unlike manual aeration, which can waste energy running fans unnecessarily, the system only activates fans when conditions require it.
The key advantage of Sentry Pac Pro™ is that it prevents spoilage before it happens, rather than reacting after damage has already occurred.
GRADUALISM
NO LARGE FRONTS.
The PAC keeps a 21 day running average to use as a targeted temperature. This 21 day average assures the air will be very close to the last time the fans ran so no big fronts are introduced. Big fronts can cause problems, including condensation. This also keeps the total hours of run time lower because never do fans have to be run to undo hours of operation out of range.
Averaging minor differences (ranges) of temperatures and RH over short periods of time works well and is a friend to good grain storage. This promotes uniformity.
The PAC avoids running with large differences over long periods of time which is disastrous due to the relationships between temperature, RH, and the grain mass and the very large energy exchanges involved. Fronts can be set up that are counter productive to desired results.
REMOVE GUESSWORK
The Sentry Pac Pro™ removes guesswork from grain storage by using automated, data-driven aeration control, ensuring that grain is properly dried, cooled, and maintained without the need for manual decision-making.
Here’s how it works:
Automated Fan Control – Instead of relying on manual checks and uncertain timing, the system monitors real-time grain conditions and automatically runs fans when needed.
Real-Time Data & Insights – Users get precise moisture, temperature, and airflow readings, eliminating the need to make educated guesses about when to aerate.
Weather-Based Adjustments – The system takes into account outside temperature and humidity to ensure optimal aeration, removing the risk of running fans at the wrong time.
Prevents Over-Drying & Spoilage – Instead of guessing how long to run fans, Sentry Pac Pro™ ensures grain reaches and maintains the ideal moisture level.
This smart, automated system takes the guesswork out of drying, preserving grain quality while maximizing weight and value
PROACTIVE NOT REACTIVE
It does not wait for the grain to start to go out of condition and then run fans. Instead the PAC monitors the weather - not the grain - to select precise conditions of temperature and humidity to produce your desired result in the grain. Over time the grain equalizes to these conditions and becomes uniform in both temperature and moisture content. The PAC keeps a 21 day running average to use as a targeted temperature.
CONtrol energy costs
The Sentry Pac Pro™ controls energy costs by using smart, data-driven aeration management to ensure fans run only when necessary, reducing unnecessary energy consumption while maintaining grain quality.
Here’s how it lowers energy costs:
Automated Fan Optimization – Instead of running fans on a set schedule, Sentry Pac Pro monitors grain conditions and outside weather to operate fans only during the most energy-efficient times.
Takes Advantage of Favorable Conditions – The system waits for the right temperature and humidity levelsto maximize drying or rewetting efficiency, minimizing fan run-time.
Prevents Unnecessary Aeration – Many traditional systems over-aerate, wasting electricity. Sentry Pac Pro stops fans when they’re not needed, eliminating wasted energy.
Load Management – By spreading out fan operation, it helps avoid high peak electricity demand charges, keeping costs lower.
By optimizing aeration cycles, Sentry Pac Pro™ cuts energy waste while preserving grain quality, leading to higher profits and lower operating costs
