BonOS STORAGE — know what your grain is doing, in every silo
Early detection. Fewer losses.
STORAGE watches the temperature of the grain itself, not the air outside. It compares every measuring point against its own history, runs the ventilation when running it actually helps, and tells you about a warming spot while it is still a spot.
How it works
Intelligent grain monitoring
Temperature profile per silo
Measuring points along the height of the silo, so you see where the grain is warming, not just that it is warming.
Warning before it is a problem
A trend that rises against its own history and against the neighbouring points triggers an alarm — days before it becomes visible in a sample.
Ventilation when it pays
The fan runs when ambient temperature and humidity make it useful, and stays off when running it would only push moisture back into the grain.
Weekly report by e-mail
One page per week: every silo, the trend, anything that needs a look. Readable by an owner who is not an automation engineer.
History you can defend
The full temperature history of a batch, from intake to loading out. Useful in a quality dispute, and useful in an insurance claim.
On your phone
The same data on a phone, so a Sunday check does not require a drive to the site.
What you get
- Continuous grain temperature monitoring in each connected silo, with the measuring points distributed over the silo height.
- Automatic or advisory ventilation control based on grain temperature and ambient temperature and humidity.
- Threshold and trend alarms — an absolute limit is not enough, because a slow rise from a low base is the more dangerous signal.
- A weekly summary e-mail plus alarm notifications when something needs attention between reports.
- Full history per silo and per batch, kept for years in the BonOS database.
- Mobile access to the live values and the history.
Why it pays
Grain that heats in store loses weight, loses germination and loses grade. By the time a hot spot is visible in a hand sample, the core of it has been developing for days and the affected volume is already measured in tonnes, not kilograms. In a silo battery holding several thousand tonnes, a single missed spot can cost more than the monitoring system for the whole site.
The second saving is on the fan. Ventilation is not free, and ventilation at the wrong moment is worse than not free — pushing warm, humid air through cool grain puts moisture back into the crop you already paid to dry. Running the fan on temperature and humidity logic instead of on habit reduces both the electricity bill and the re-wetting.
The third is quieter. A documented temperature history from intake to loading out changes the conversation when a buyer disputes quality, and it changes the conversation with an insurer after a loss. It costs nothing extra once the measurement exists — it only has to be recorded and kept.
Frequently asked questions
How many measuring points does a silo need?
It depends on silo diameter and height, and on whether the silo is a flat-bottom or a hopper type. The point spacing is set at design time so that a developing hot spot cannot sit between two sensors — that is part of the system assessment, not a catalogue number.
We already have a temperature system. Is it wasted?
Not necessarily. If the measuring cables and the reading hardware are sound, BonOS reads them over open industrial communication standards and adds the trend logic, the reporting and the mobile access on top. The assessment tells you honestly which parts are worth keeping.
Does it control the fans itself, or only warn?
Both are available. Many operators start in advisory mode — BonOS says when ventilation would help — and move to automatic control once they have seen a season of its decisions. That is a deliberate order, and we recommend it.
What moisture content should grain go into store at?
For maize, MSZ 12540:1998 puts the target at 14.5%, and in practice storage in this region is done at 13.5–14%. Below roughly 15% the water release curve flattens sharply, so drying further costs a great deal of energy for very little water — one of the most common and most expensive habits in the industry.
Is this the successor of the STS pages on the old website?
Yes. STS — silo temperature monitoring — is now BonOS STORAGE, with the same function and a wider scope, including ventilation control and the weekly report.
