In Dooch’s lab in Korea, we have pump-optimized inverters and controllers which are exported to 22 countries around the world. Through such pump-optimized inverters and controllers, it reduces the noise and vibration generated during the operation of the pump. Also, by controlling the rotation speed of the pump, it operates at optimum operating point and increases the system’s safety and saves energy.

If you need controllers over 30HP, we can provide the optimized pump controller (OPC), which is compatible with any general inverters in various countries and field conditions.

As our booster system consist of individual inverters, each inverter communicates one another. Even if one inverter or one pump is out of order, the other inverters can operate automatically. As a result, it ca far more enhance the stability of water supply.
