Special coated O-rings for renewable energy application

Our renewable energy customer manufactures wind sensors for a variety of applications in different environments. This seal application, within ultrasonic wind sensors, is designed for wind turbine control. We explore here why special coated o-rings are needed for this application, regularly exposed to harsh conditions. 

The application

For optimal performance, wind turbines need critical, consistent and reliable data on wind speed and wind direction measurements. Therefore, we recommended special coated o-rings for this renewable energy application.

The sensors that provide this must be able to operate continuously for many years, sometimes in the harshest of weather.

Operating conditions are extremely challenging because fluctuating, extreme environmental changes constantly batter the wind turbine sensors (and accompanying electronics).

Depending on the location of the turbines, temperatures can range from -40°C to +90° C. Additionally, humidity changes from 0-100%, and turbines are subject to rain, hail, snow, ice, lightning, vibration, sand, corrosion and altitude.

Our sealing solution

For this application, the required life cycle of the sensors is10+ years. To achieve this, the electronics and sensors need a robust protective housing. This design requires a series of reliable, consistent, high-quality seals to house the electronics and sensors. These will perform without compromise in challenging conditions. Our engineers subjected the sensors to rigorous testing to confirm life cycle performance, ultimately awarding them an IPX6K rating.

Each sensor size uses a set of environmental seals in the separated top and bottom sections. Together with our customer’s intensive testing program, we specified EPDM o-rings (which offer exceptional ozone resistance) with a special coating.

The coatings are colour coded for identification purposes according to the size of sensor. Therefore, this creates a fool-proof assembly process with no risk of error by operators.

Successfully built into nearly half of wind turbines globally, our range of seals have been cycle tested and approved by our customer.
