Reliability & Safety
- Second Level: Electronic control system activates mechanical brake with shaft lock and electromagnetic induction brake.
- Third Level: Passive springs deploy, putting the turbine blades in a stall position, spoiling the rotor
aerodynamics and subsequently its ability to rotate.
DATA INPUT & MANAGEMENT
- Remote Control: Allows the remote customization of the wind turbine to provide the optimum performance at every site.
- Storm Detection: Intelligent storm detection algorithm and automatic safety lock protects the turbine in the event of dangerous gusts/hurricane weather.
- LCD display in control box. Can output to local PC or be monitored remotely via the internet.
CONSTRUCTION & MAINTENANCE
- Anti-Corrosive Blades: The blades and nacelle are treated with epoxy paint and hermetically sealed. This gives corrosion and saline protection, making the turbine ideal for island, coastal or desert deployments.
