Dirt builds up on the blades little by little and the fan goes out of balance without you seeing it, until vibration triggers the breakdown. We place a wireless sensor on the structure and watch it 24/7: we catch imbalance, looseness and bearings days or weeks ahead.
In a fan, the most common problem is imbalance, but it isn't the only one. This is what we watch:
Dirt or erosion on the blades that unbalances the mass: peak at the running speed.
Loose fixings and mechanical play in the base or structure, common in large fans.
Bearing wear visible as characteristic frequencies in the spectrum.
Between motor and fan, especially in belt or coupling drives.
Three measurements that together give a reliable picture of the fan's condition and how it evolves.
The overall vibration value (RMS) tracks the trend: a slow rise reveals progressive imbalance from fouling.
Frequency analysis (FFT) tells imbalance (running speed) apart from looseness, bearings or misalignment.
Temperature complements vibration and helps detect abnormal friction in the bearings.
From the first deviation to a planned intervention. Illustrative example of imbalance from blade fouling:
Vibration at the running speed starts to rise slowly.
The FFT confirms imbalance from blade fouling or erosion.
Severity crosses the threshold. We alert you to clean or balance.
Cleaning or balancing in a scheduled stop, not in an emergency.
Vibration, FFT and temperature, right on the fan.
Trend and spectrum continuously, against the fan's thresholds.
"Fan V-2: imbalance rising; consider cleaning."
The sensor attaches to the fan structure. No electrician and no changes to your installation.
Installation doesn't require stopping the fan, so the process keeps running.
For centrifugal and axial fans and industrial blowers from different brands.
Dust build-up, caked dirt or blade erosion mean the mass is no longer evenly distributed. That raises vibration at the running speed and shows up clearly in monitoring.
Centrifugal and axial fans and industrial blowers. The sensor attaches to the structure, so it works with different brands. We assess each case to confirm feasibility.
No. The sensor is wireless and attaches without stopping the line and without an electrician.
Imbalance from blade fouling or erosion, looseness, misalignment, bearing problems and behavioural changes that anticipate failure.
