1. Save energy: For IE4 or IE5 motor , the effiency maybe just improve 1~2% effiency than IE3 motor, but the price are higher 50% than normal IE3 motor. Pump with VFD, you can get the accurate flow and head , you will not waste any energy, at least 25% energy than IE5 motor without VFD.

2. Save money:To save money not only embodied in save energy,  for the traditional VFD, you have to put the VFD into the pump controller box , connect with reply , PLC ,Contactor etc, and it needs a lot of raw material, meanwhile it is very Complex to connect so many wires, it needs a very professional electric engineer to install and solve the trobleshooting. Now Aikon VFD built-in the pump operation logic to IP55 VFD, just connect the VFD with motor junction box directly. Very easy and very economic.

3. Friendly: Soft start and soft stop, friendly to pipe, motor and pump, you will don't worry for the water hammer.

4. Protection : Overload protection, over-voltage protection can be set, under voltage protectioncan be set, short circuit protection, over-current protection, parameter locking
