Features:
1. High efficiency energy saving.
System can set pressure by the need, and it can automatically adjust the  pump running speed and the number of the running pumps.It can make the device run on the best state of efficient energy-saving
2. The pressure of water supply is stable
The system achieve closed-loop control and can automatically adjust the system pressure and set the value of the pressure.It can make the system pressure constant.
3. Convenient and simple operation
The system is automaticly controled by the frequency converter or the frequency converter with the intelligent controller,the operation is simple.
4. To extend the life of the motor and water pump
All pump are soft starter, eliminating the impact of current when starting and extending the useful life of equipment; Every pump is cycle soft-starter, so that the pump will not be rusted while it is unused for a long time or it will not be frayed while it is frequently used
5. Improve the protection
With a short circuit, overcurrent, overvoltage, overheating, overload protection, etc., pumps running if there is failure, automatically stop working and alarm output; system has a self-test, to determine fault, fault memory, fault display, automatic start-up features such as back-up pump
6. Small flow subsidiary AutoRun feature small pump
Subsidiary with access to a small pump, allowing the system to run at night or other low flow rate cases, the automatic closure of the main pumps, small pumps to open a subsidiary in order to avoid the opening caused by high-power pumps waste.
7. Frequency regulation, effective way to avoid the "water hammer" phenomenon.
8. Inverter and controller to facilitate the programming and set up simple, easy to grasp.
9. Equipped with a manual switch control to ensure continuous operation of security equipment
*0. Communications and computer serial port to connect, to achieve direct control over the computer network.
