Features of vertical wind tunnel 20kW:
1. Efficient Generator of wind tunnel 20kW:
Hummer 20kW wind tunnel is one of the most advanced generators in the world. Made of refined permanent magnetic material, special copper alloy, aviation aluminum alloy and stainless steel, it is highly efficient in power. Due to its smallness, it is able to be placed inside the nose cone to reduce air resistance and increase efficiency.
Smart Control of wind tunnel 20kW:
H9.0-20KW wind tunnel is controlled by a comprehensive smart system. Through our years of monitoring on wind turbine operation, we successfully develop an automatic control system for small and medium scaled wind turbines.
This smart system is able to automatically seek wind direction and constantly monitor generator working status, rotation speed, generator temperature, wind speed and direction etc. All data will be transmitted to control center.
When abnormal situation takes place, our control center will instruct wind turbine to deflect from wind direction. After problem is released wind turbine will turn to face wind direction again and resume generation.
