Aerion Helios 4.2MW Utility Wind Turbine

The Aerion Helios 4.2MW Utility Wind Turbine is engineered for grid-scale performance and quiet reliability. This three-bladed, white tower with high-visibility red tips leverages a permanent-magnet direct-drive generator, active pitch and yaw, and advanced SCADA for real-time control. Designed for utility wind farms and coastal installs, it delivers exceptional efficiency across variable wind regimes while maintaining low acoustic output and minimal maintenance requirements.
