An automatic dosing product developed and produced by a dosing device, mainly used for the treatment of boiler feedwater, circulating water, hydrazine, phosphate, etc. in power plants, and can also be used in industries such as petroleum, chemical, environmental protection, and water supply systems.

The unit combination dosing device mainly consists of a solution tank, a metering pump, a filter, a safety valve, a check valve, a pressure gauge, a buffer tank, a liquid level gauge, a control cabinet, etc., which are integrated and installed on a base. Users only need to place the combined dosing device in the dosing room, connect the inlet and outlet, and turn on the power to start and put it into operation. This factory based complete set of devices can greatly reduce the workload of design and on-site construction, providing reliable guarantees for the quality, safety, and on-site operation of the entire system.
