We eliminate vibration in rotating equipment right at your site in Portugal — without removing the rotor. We measure first, find the cause, and only then balance.
We measure vibration and check whether the cause is actually imbalance.
Based in Vila Nova de Gaia (Porto). We work at the customer's site.
We balance the rotor in its own bearings, without removal or transport.
A follow-up measurement and a report with vibration readings before and after.
Vibration is a symptom, not a ready-made diagnosis. Balancing helps when the source is imbalance in the rotating part. Shaft misalignment, worn bearings, loose mounting, or resonance call for a different fix — which is why we start with a measurement.
This information lets us clarify the task, check whether on-site work is possible, and prepare an estimate.
Describe Your TaskFrom the initial measurement to the final check, plus instrument supply and staff training. Our main focus is dynamic on-site balancing.
We correct imbalance directly on the installed machine, in one or two planes, without removing the rotor. This is the right choice when measurements confirm that the vibration is caused by imbalance.
Learn More →We measure vibration parameters, combine them with the machine's history and a visual inspection, and rank the likely causes — so you fix the right problem first.
Learn More →Fans, smoke exhaust fans, and supply air units. Two-plane balancing of the impeller in its own bearings — quieter and vibration-free.
Learn More →Level, spectrum, speed, and phase. You find out where the machine vibrates, how strongly, and at which frequencies. One high number on its own is not yet a diagnosis.
Learn More →A portable two-channel vibration analyzer and balancer — the same instrument we use on site. For those who want to balance equipment themselves.
Learn More →We explain the measurement method and hands-on work with the balancing instrument, so your team can balance equipment on its own.
Learn More →We balance almost any rotor that can be safely run on site. Feasibility depends on the design, access, operating speed, and the availability of correction planes.
Don't see your machine on the list? Send us the type and speed, and we'll tell you whether on-site balancing is possible.
We clarify the equipment, symptoms, operating speed, location, and access to the rotor.
We record the baseline vibration at operating speed and determine the nature of the fault.
If the cause is imbalance, we calculate and fit the correction weight. If it isn't, we provide our assessment.
We repeat the measurement under the same conditions and hand over a report with readings before and after.
Real jobs: the drop in vibration before and after balancing, sensor placement, and fitting correction weights right on site.

In the draft, the grid is assembled from gallery photos. On the live site, it will be replaced by a live Instagram feed widget (LightWidget / SnapWidget / Elfsight).
The price has two parts: vibration diagnostics with a report, €300 per unit — always payable, and balancing — only if the measurement confirms it's possible. Move the sliders and the calculator will instantly show both amounts: the full job, and the option if balancing turns out not to be possible.
This is the full scope of the visit, not just fitting the weight:
The correction weights need to be attached — either bolted on or welded. This gives two options, and they affect the final price:
We mark where each weight goes and what size it should be; your fitter or welder attaches it under our supervision. Included in the base price — usually the fastest option, since your people know their own equipment.
We attach the weights ourselves: bolted connections, standard mounting points, drilling. For sites without a fitter available. Cost: +€150 per rotor.
Welding the weights on is a critical operation: a second specialist, a welder, comes out with their own equipment, and the weld is inspected. Cost: +€400 per rotor.
For the visit to succeed in a single trip, we need a few things from you — small, but important. Here's what should be ready before we arrive.
Balancing is only carried out on machines that are in good working order and properly secured in place: bearings in working condition, frame free of cracks, fasteners tight. If we find a fault during inspection, repairs are needed first. In that case, we carry out vibration diagnostics, identify the cause, and prepare a report — and charge only for diagnostics and travel, not for balancing.
Caked-on dust, dirt, and product buildup are themselves a source of imbalance: it sticks today, it flakes off tomorrow. The rotor needs to be cleaned before balancing — otherwise the result won't hold, and the money will be wasted. If cleaning isn't possible on site, we'll tell you honestly before starting the work.
Balancing requires 3–6 start-ups of the machine. We need one of your staff who knows the equipment, operates the start-up and shutdown, and is responsible for job safety and work authorization. Our specialists do not operate your equipment themselves — this is a safety rule.
A standard 220 V outlet is needed near the machine to power the measuring instrument and laptop. An extension cord works too — what matters is stable power during the measurements.
We need access to the bearing housings to mount the sensors, space for a reflective marker on the shaft, and access to the rotor to fit the weights — an open hatch, a removed cover, or a window in the casing. If access requires disassembly, we'll agree on that in advance.
Send us photos of the unit and its nameplate, plus a short video of it running, on WhatsApp — before the visit, we'll tell you what to prepare, whether on-site balancing is possible, and how much it will cost. This is free.
Usually, yes. Balancing is performed in the machine's own bearings, provided there is safe access, the rotor runs stably, and conditions allow for several start-ups.
No. Shaft misalignment, worn bearings, loose mounting, resonance, or parts rubbing against each other can shake a machine just as much as imbalance. That's why we measure first and only add weight afterward.
Two parts: vibration diagnostics with a report, €300 per unit (always payable) + balancing based on rotor size (S +€250, M +€450, L +€700, XL from +€1,200), one or two planes included. If balancing isn't possible — for example, the bearings are worn out — you pay only for diagnostics and travel, and receive a report stating the cause. Attaching the weights: your own staff — included; our fitting work without welding +€150, with welding +€400 per rotor. Travel: 20 km included, then €0.60/km round trip. Minimum invoice — €500, + VAT.
Yes. We're based in Vila Nova de Gaia, and we schedule visits across all of Portugal. Let us know where the machine is, and we'll sort out the travel.
A balancing report with vibration readings before and after, the mass and position of the correction weights, and, if needed, an assessment of the machine's condition.
We'll answer your questions, clarify the details, and let you know what's needed for an estimate and a visit.
