INVT CHV160A VFD Control for ID Fan
There are many medium voltage variable frequency drives been used in cement fans transform project of cement plant's raw material milling fan. This case cement plant product capacity is 3000t/d. They original use with the valve air volume adjustment. It is the way of constant speed regulation. The valves open degree 30%-40%, which result a waste of energy.There is a medium voltage variable frequency transform project of cement plant's high temperature fan (ID Fan). This cement plant product capacity is 2500t/d. They original use with hydraulic coupler speed regulation .
