Inside Freen-6:
A Look at Innovation
-
Easy-to-Install Foundation
Prefabricated, non-buried foundation for simple and stable installation.
-
Lightweight Blades
Blade proportions ensure optimal aerodynamic performance, reduced vibration, and enhanced stability while remaining wildlife- and neighborhood-friendly.
-
High-Efficiency Generator
No gearbox. A permanent magnet generator, adapted from our proven models, ensures reliable operation with minimal friction losses.
-
Compact Rotor
The compact rotor size is tailored for home environments, delivering power with less noise and a visually refined design.
-
Low-Friction Components
Direct drive design reduces energy loss and extends lifespan.
-
Slow Rotation, Maximum Safety
Operates at 90 RPM – slow enough to ensure safety for humans and animals and maintain quiet operation.
-
No Wind Orientation
Thanks to its vertical-axis design, the turbine performs efficiently regardless of wind direction — no active orientation needed.
-
Monopole Tower
Easy to install, variable height available for different application types.
