Why do wind turbines need fans?

Fans are also used for control cabinet ventilation, as the components used here are particularly temperature-sensitive. Fans are also essential when it comes to nacelle ventilation to ensure optimum operating temperatures regardless of ambient temperatures. We develop solutions for challenges that arise in the operation of wind turbines.

Are there different fans for wind turbine cooling and ventilation?

We have different fans for cooling and ventilation for wind turbines. For example, our fans for generator cooling are double-flow housing fans from the RD model range, which have a particularly robust and hard-wearing design. The fans’ welded housing can also withstand high vibration or shaking stresses and offers excellent corrosion protection.

Which type of fan is best for a wind turbine?

For wind turbine applications, axial fans are ideally suited for tower or nacelle cooling. Figure 3. Centrifugal fan. Source: Rosenberg Centrifugal fans move air in a direction perpendicular to the axis of a fan wheel, which consists of a series of blades mounted on a circular hub (Figure 3).

Why should you choose Ziehl-Abegg wind turbine fans?

Fans for wind turbines from ZIEHL-ABEGG represent the very best of ventilation, control and drive technology. The high-performance fans make it possible to realise more powerful wind turbines. This reduces the investment required per feed-in capacity for a wind turbine and, as a result of these savings, increases the return.

Do you need a frequency inverter for fan control in wind turbines?

And if you need a cost-optimised frequency inverter for fan control in wind turbines with IEC standard motors, we offer Icontrol, a frequency inverter without a built-in sinusoidal filter, which is also available in protection classes IP54 and IP20. Fans are not only used for generator cooling and nacelle ventilation in wind turbines.

Why do wind turbines need Rosenberg fans?

These fans can improve generator efficiency and increase the operational life of wind turbine components by creating a constant distribution of temperature. Rosenberg fans can ensure the needed cooling capacity, low acoustical noise and ability to operate in harsh environments with improved corrosion protection.
