Fan Selection Software
Operating point
Select fan type
CPR-EC
Controller
The CPR-EC controller controls the rotational speed of the EC fan, stabilizing the pressure difference between the ventilation duct,and the reference pressure.
Application
The CPR-EC controller controls the rotational speed of the EC fan, stabilizing the pressure difference between the ventilation duct, and the reference pressure. CPR-EC has a self-tuning predictive controller
with control deterioration detection module and restarting tuning automatically. The controller selects the settings to provide optimal operation of the fan ensuring at the same time maximum comfort of using the system.
