1. Energy buffer

The system includes a rechargeable battery for buffer function of up to 1000 hours and more

(depending on type of application).

2. Energy source

A flexible solar panel ensures practically unlimited energy supply from daylight.

3. Impedance measurement

Ice thickness and other layers, such as dirt, are detected and quantified directly on the blade surface.

4. Temperature measurement

Surface temperature is measured with an accuracy of 0.25°C.

5. Wireless

The sensor transmits data to the base station with a minimum range of 250m.

Benefits and advantages

Safety

All our systems have been qualified by independent certification bodies

More output

Using our reliable solution will help you achieve more output by increasing the efficiency of your wind turbine

Up to 80% less downtime

Exact ice detection reduces the downtime of your wind turbine by up to 80% per year

No ongoing maintenance costs

Our system is maintenance-free and therefore saves you operational costs

Rapidly ready for operation

Retrofittable - in addition, no calibrations, drillings, openings or wires are required

Buy what you need

Our flexible and modular systems enable you to buy what you need now, while staying open for future expansions up to certified automatic restart systems (also DNV GL certified)

Extend the lifespan

Icing on the rotor blade results in a temporary imbalance, which accelerates the fatigue of all components - this can be prevented by an ice detection system

Precise ice detection

Precise detection of icing and exact local detection on rotor blade (including measuring the ice thickness) regardless of visibility conditions or access

Maintenance costs and operation is one of the main cost factors of a wind turbine and can make up to 40% of total cost. Rotor blade maintenance alone can account for up to one fifth. The majority of these costs can be traced back to missing or insufficient condition maintenance solutions. Currently the majority of rotor blade maintenance is carried out by industrial climbers who inspect and, if necessary, repair rotor blades. The largest international wind turbine manufacturers emphasize the need for continuous condition monitoring systems, especially for rotor blades.

eoIACC is the first on- blade continuous condition maintenance sensor based on sensors distributed over the rotor blade surface, especially on the blade tips.
