BERDAN-TECH EVOLUTION OF WIND TECHNOLOGY

The BE-Wind product line is unique in the world, it is the only dual vertical wind system with a Deflector (Diversion) shield on the market today. This design has come about after many years of development and testing. The patented design is going to revolutionize the Function and the way we approach small wind technology.

All vertical wind systems on the market today, regardless of their specs, are very inefficient, just because of the process in which they produce rotation.

1) The same wind that creates rotation on any vertical system also creates resistance. The fact that the parabolic drive side has a larger volume of air flow and force, creates rotation.

2) The Solution to overcome this situation is to block or divert the air flow from the opposing force side of the blade.

But it is not just simply placing a wall in front of the blade. There are many factors to the position and distance this deflector must be at, or it will simply cause much more problems. At BERDAN-TECH we have tested this in a wind tunnel and used Flow analysis.

To determine the proper formula for making this work effectively.
Once this formula was developed by a team of engineers, the technology sprang forward, to develop a structure to support the loads and allow the system to rotate smoothly into the wind, so that the Deflector would always maintain its position with constantly changing wind direction. Since the wind was being diverted to both sides of the deflector, it seemed logical to place a second turbine on the opposing side. This opened the door to solve more issues with all wind turbines.

3) The result was a high performance low wind system that solved many of the issues in the small wind industry.

By creating this wind system, we resolved many issues that have plagued the small wind industry for all these years.
a) By increasing and blocking the wind flow to the back side of the blades, we have solved the issue of areas with low wind.
b) Results have shown start up rotation speed in 3-4 mph creating low voltage power at 5-6 mph. (12 – 24 volts) perfect for battery storage or charging.
c) With expanding blade lengths, we can develop torque to turn low resistance Axial Flux generators and produce 120 volts for input at 8-10 mph.
d) The requirement for 30-60 foot poles to capture high winds
are now just an option, resolving the expense of
very high poles with very high service charges.
