Above mentioned performance values were measured in the up-to-date aerodynamic tunnel at LOMANCO under the circumstances simulating real utilization. Tests were performanced according to the latest science knowledge. Independent Ryan Engineering (Arcansas) checked the methodology. Lomanco has been permanently checking their efficiency and compare it with the competition turbines. And that is the reason why they keep their strong position in the world.
