VFD ( Veritable Frequency Device ) .

Frequency conversion technolog

A.Able to change vibration frequency according to different raw materials and different

types of blocks (range from 50-90HZ)

B.With the frequency inverter, the machine is able to increase or decrease the vibration

speed in very short time.

This will greatly save the cycle time, and increase the productivity.

C.Save energy up to 30% due to high energy transfer efficiency

D.Allows the motor to adjust its speed linearly, avoiding frequent acceleration that can burn out the motor. Extends the life of the motor
