DW58

Maximize your annual energy output when (re)powering medium wind distributed energy sites

The DIRECTWIND 58 is the result of EWT commitment to continuous innovation and improvement. This 58-metre pitch-controlled, variable speed wind turbine is designed to deliver higher annual energy outputs in medium wind speed (class IIA) sites than any similarly rated turbine. Optimized for distributed energy generation, it combines high yields with outstanding reliability and low noise. Our direct drive technology means fewer moving parts, so less maintenance and more availability. Meanwhile the aerodynamic rotor design ensures ensures high efficiency and reduces 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
  • Blade heating
  • 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 46 and 69 m
