Wind Energy-Why the Koender's Compressor design is the Best in the Industry!!

1) Koenders has 20 years experience in developing a balance of blade and piston -diaphragm size to ensure the most optimal, tested and proven design for maximum performance under varying wind conditions.

2) It has been proven beyond a doubt that the diaphragm size to blade surface ratio must be such that the system aerates with the perfect balance of excellent aeration performance without stalling.

3)The Koenders design balances the benefits of excellent air volumes at the high wind speeds as well as providing extended hours of low wind speed performance without stalling. This blade size to compressor size balance maximizes effective pond aeration and system reliability.

4) The amount of aeration achieved depends on a few critical things. The depth of the airstone diffuser in the pond water will reflect the amount of "back pressure" on the compressor (one pound per square inch of pressure for every 2 Ft of water depth).

5) Larger diaphragm - the more air one can expect? In theory this sounds like it would be advantageous. Only if larger horsepower demands can be met with a larger diaphragm produce more air, and only an increase of wind speed or blade surface will satisfy this demand. When larger horsepower demands are not met, a windmill either stops or slows down. This over demand of available horsepower will shorten actual windmill running times which reduces the overall aeration program and results in a loss of air production not a gain.

6) An analogy would be that of the gearing of a bicycle; If a bicycle does not have the option of multiple gears, the designer must choose a gear ratio which will satisfy, hill climbing, level riding and descents or----low winds, moderate winds,and high winds.

7) Another negative condition created by the over sizing of the piston or diaphragm is the increased force on the connecting rod, bearings and other windmill related components. A 7 inch diameter piston-diaphragm with a system back pressure of 10 PSI will require 384 lbs of force each stroke of the piston, while a 10 inch diameter piston-diaphragm will increase that force to 785 lbs! Think of the design changes to the crankshaft, bearings,connecting rod etc... that a manufacturer must allow for approximately 25 PSI on a 10 inch diameter piston-diaphragm which would equal a full ton of force(2000 lbs).

When considering buying a windmill aeration system make sure that the design of any units are thought through in all aspects-most copy cat products have only changes specific components of the windmill aeration systems and failed to totally engineer all components-so the integrity, reliability, performance and endurance of the unit is not validated. For example, a larger diaphragm diameter will not be effective in the field unless the rest of the system has been sized to match and with stand the forces that will be stressed on the windmill.

With Koenders we have the single diaphragm and dual diaphragm windmill aeration systems-both units use our 7 inch diaphragm an illustration of the integrity of our design. The dual diaphragm windmill aeration system pumps double the amount of air compared to our single diaphragm windmill at relatively the same wind speeds.
