Precite ColumnOS · Distillation column automation
Distillation column automation that runs your column on its own.
ColumnOS holds the pressure across your column every second and drives the boiler by itself. Every batch separates at the same point and uses only the steam it needs. It retrofits the column you already have.

✓ Retrofits your existing column
✓ Pressure or temperature control
✓ Live on your phone, 24×7
2
Control modes
Pressure or temperature, switched on the screen.
4-step
Proportional steam
25, 50, 75 and 100% instead of on and off.
24×7
Cloud monitoring
Every reading live on your phone and saved.
Retrofit
No new column
Fitted to the column you already run.
TWO CONTRL MODES
Run it on pressure. Or on temperature.
Same panel, same valve, same column. The operator chooses the mode that suits the product and switches it on the screen.

PROPOTIONAL STEAM CONTROL
Not a switch. A throttle.
A on/off valve send full steam or none, so the column overshoots, cools and overshoots again. ColumnOs opens it at 25, 50, 75 or 100% - only the heat the column can use.

On the plant floor
One screen. Everything on it.
Your operator works on a panel at the column: pressure at the top and bottom, the gap between them, material temperature, boiler, valve position and mode. You see the same screen on your phone, and every reading is saved to the cloud so the batch record writes itself.

PRECITE INTELLIGENCE
Every batch, scored against your best one.
Every reading lands in the cloud, so ColumnOS learns how your column behaves with each product - purity, steam per kg, cycle time - and flags the run that drifted.

Track whatever matters to you
The dashboard is built around your process. Crude input quality and grade, feed quantity per batch, yield per cut, reflux ratio, cooling water, cycle time, operator on shift - if it can be measured, it can be tracked and compared.
Your data, your column
Nothing here is a generic benchmark. Every comparison is against your own best runs on your own column, so the targets are ones your plant has already hit. Figures shown are an example of the analytics view.
What changes
The column stops depending on who is on shift.

Consistent quality
The same set points, held the same way, on every batch and every shift.

Less steam
Heat goes in only as fast as the column can use it. No more burning steam at full open.

Less operator dependency
No single experienced hand holding the plant together at the valve.

Better yield
Sharper cuts mean less of the valuable fraction lost into the one next to it.

Less operator dependency
No single experienced hand holding the plant together at the valve.

AI on every batch
Each run scored against your best, with drift flagged the next morning.
BEFORE AND AFTER
Run by hand vs run by COlumnOS.

WHERE IT FITS
If it has a column, it can run itself.
Every one of these industries separates liquids by boiling point. The product changes; the control problem does not.
