VARIABLE DRIVE CONFIGURATION
1- Operating principle :
The variable drive is used for one of its most basic functions, namely overspeed operating.
Thanks to the types of fan curve used, we can make a fan operate at a speed from 70 to 87 Hz.
With conventional starting up, it would not be possible to operate it above 50 Hz (electrical system frequency).
Thus, we can operate at overspeed while keeping the system vacuum constant.
