DW54

With a 54-metre rotor and a range of tower heights, the DIRECTWIND 54 is the ideal choice for distributed energy generation in low wind (IEC class IIIA) sites where planning permission and tip-height restrictions apply.

Thanks to EWT’s continuous market-driven innovation, the DW54 delivers higher yields than similar-sized turbines in the same wind class. Meanwhile, our direct drive technology and aerodynamic rotor design ensure excellent reliability, availability and efficiency while also reducing noise.

Options

You can choose from a wide range of options to tailor your EWT turbine to your specific requirements and local conditions. These include:

  • Aviation light
  • Shadow flicker
  • Ice detection
  • Cold climate package
  • Black blades
  • Climb assist
  • Low-voltage ride through (LVRT)
  • Automatic voltage control
  • Frequency response
  • Power curtailment

1. Rotor blades
Large rotor diameter to achieve high energy yields. Optimum aerodynamic performance, resulting in high efficiency and low noise levels.

2. Variable pitch
Each blade is automatically pitch to control the generator rotation speed

3. Nacelle design
Spacious nacelle design for excellent serviceability and maximum safety.

4. Direct drive generator
Fewer rotating parts reduce mechanical stress, leading to a lower maintenance need and therefore superior availability levels.

5. Tower design
Type Conical tubular steel, internal ascent. Hub heights 40, 50 and 75 m
