The Electrolytic Chlorination Unit （ECU） was developed for the generation of sodium hypochlorite through the electrolysis of the salt water. ECU systems provide for on-site, on-demand production of sodium hypochlorite solution from salt water, and electricity.

The ECU is a fully automated, pre- packaged on-site hypochlorite generation system designed for fast and economical installation, safe operation, and easy maintenance. Skids are shipped completely piped, wired and tested.

The anodes used are carried a five year warranty after installation and commissioning. Automatic control of the supply voltage combined with the flow rate control system ensure a virtually operator-free performance. The number of anodes in the electrolyzer can be customized to produce the desired quantity of chlorine. This system flexibility provides a significant reduction in power requirements and plant cost. A PLC control system provides for the fully automatic operation of the unit including all control, monitoring, alarm and interlock functions. Having set the flow rates for salt water and dilution water, all that remains on site is to turn the start switch.

3.     Reliability and durability

-        Long life guarantee for the anodes

-       Easy installation and start-up

-       Reliable process and compact construction

Operation

The salt water enters the electrolyzer cell. The DC current applied produces sodium hypochlorite and hydrogen. The hydrogen together with the sodium hypochlorite solution is discharged into the product storage tank. An air blower is used to dilute the hydrogen to well below its flammability limit and to force ventilate it to a safe outdoor discharge point. The sodium hypochlorite solution produced is added to the water which need to be disinfected.

The flow rate control system which installed on the pipe, will automatically shut off the system while the flow rate is low. The DC output is adjustable from 0-100%, it allows precise production of the sodium hypochlorite.
