Cost saving at minimum ventilation

Controllable fans are controlled by a transformer, a triac or a frequency controller. The difference between the Intelligent Fan Drive and a triac / transformer control is clear: more than 60% energy savings.

Does the Intelligent Fan Drive also have a higher performance than the frequency controller? The answer is YES. Especially at minimum ventilation the Intelligent Fan Drive works optimally. At a RPM of 60% or lower you save extra energy! Scientific research shows that 80% of the year fans function below this percentage in pork and poultry houses.
