ED3100-FP Series Energy-Saving Variable Frequency Drive for Fan and Pump
It is common practice to allow for some deviations from the rated capacity in design of industrial fans and pumps. Designers also add dampers or valves to regulate the flow of air or liquid into and out of the fan or pumping system. These flow control methods are simple but also wasteful. As a matter of fact, the significant usefulness of our variable frequency drive comes from the large amount of energy it saves in the pump or fan speed control system, eliminating the need for any dampers or valves.
Features of Variable Frequency Drive
1. Overload capacity: rated current×120%/min, rated current ×150%/sec
2. Smooth startup protects the fan and pump from shock load.
3. The PLC system, coupled with the bypass control, ensures the variable frequency drive can freely switch between two fixed frequencies.
4. The speed tracking control allows the drive to deliver a motor speed the same as the previous one. In this way the decelerated motor can retain its speed without experiencing shock load.
5. Automatic energy-saving features adjust the motor speed according to the varying electric loads.
6. Built-in PID functions offer both open loop and closed loop controls.
7. Various other control and protection features are available.
Applications of VFD
Our variable frequency drive can be connected to the fan in an industrial or residential boiler, mine ventilation system, cement or ceramic furnace, dust collection system, the metro station, large workshop, sports venue, and the air compressor.
The variable frequency drive also can be attached to the pump of the urban heating supply system, central air conditioning system, cooling water system, water plant, sewage treatment factory, dyeing equipment, and water supply system
