Ensuring durability with non-destructive coating inspection

Comprehensive inspection of all coating layers.

100% non-destructive and non-ionizing technology.

Over 30% of blade maintenance costs come from surface defects

1 in 3 repairs must be redone due to inaccurate inspections

The maintenance costs for wind turbine blades can reach €2,000 for each megawatt of energy the turbine can produce.

Traditional inspection methods fall short

Visual inspections lack reliability

Visual inspections are the most commonly used method for assessing blade coatings, but they rely heavily on the inspector’s experience and subjective judgment. This means defects can be easily overlooked, especially when they are beneath the surface. Furthermore, environmental conditions such as lighting or weather can impact visibility, leading to inconsistent results.

Precise measurement of each coating layer thickness

Evaluation of paint adhesion to the blade surface

Detection of invisible defects like bubbles, pores, and orange peel

Running 24/7 since its installation, it provides unprecedented data on the painting process, enabling a 15% cost reduction through material, energy, and defect minimization—delivering both economic and environmental benefits.
