As a leading manufacturer in the water treatment industry, Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is proud to present our automatic liquid chlorine equipment, developed for facilities that demand reliable, safe, and efficient disinfection solutions. This system is specifically engineered to operate with salt purity of NACL greater than 89%, ensuring high chlorine yield while minimizing maintenance. By integrating PLC control, our equipment delivers precise dosing and seamless automation, significantly reducing manual operation and human error. Whether you are upgrading existing disinfection infrastructure or building a new water treatment facility, this automatic chlorine generation system is built to deliver consistent performance with low operating costs.
Our equipment transforms common salt into liquid chlorine on-site, eliminating the hazards and logistics costs associated with transporting chlorine gas or sodium hypochlorite solution. It is a safer and more environmentally friendly alternative that aligns with modern industrial standards. Below, we detail the key features, technical specifications, and benefits that make this system an ideal choice for diverse applications.
Main Features
Fully Automatic PLC Control: The system uses a programmable logic controller to manage the entire chlorine production process, including salt dissolution, electrolysis, and dosing. Operators can set parameters via an intuitive touchscreen interface, and the system adjusts automatically to variations in water flow and quality.
High Purity Salt Compatibility: Designed for NACL purity above 89%, this equipment ensures optimal conversion rates and lower salt consumption, reducing operational expenses and the frequency of salt replenishment.
Robust Anti-Corrosion Construction: All parts that contact saltwater or chlorine are made of high-quality PVC, UPVC, or titanium, ensuring long service life even in aggressive chemical environments.
Integrated Dosing Module: The equipment includes a precision dosing pump and flow meter, allowing accurate injection of chlorine solution into the treated water stream. Adjustable dosing rates cover a wide range of applications, from small pools to large industrial cooling loops.
Safety Redundancy: Multiple sensors monitor chlorine gas concentration, pressure, temperature, and solution level. In case of any abnormality, the PLC triggers alarms and automatically shuts down the system, preventing potential hazards.
Skid-Mounted Design: The complete system is pre-assembled and tested on a compact skid, making installation quick and cost-effective. It requires minimal footprint and connects easily to existing water piping.

Why Choose ZLN Automatic Liquid Chlorine Equipment?
This system is engineered for reliability and efficiency, offering benefits that translate directly into lower operational costs and improved safety:
On-Site Generation Economizes: Producing liquid chlorine from ordinary salt is far cheaper than purchasing chlorine chemicals, especially for large-scale users. The payback period is typically under two years.
Lower Chemical Logistic Risks: No handling and storage of hazardous chlorine gas or high-concentration liquid bleach, reducing insurance and compliance burdens.
Consistent Water Quality: PLC control ensures that chlorine residual remains stable, meeting disinfection standards even when water demand fluctuates.
Minimal Operator Supervision: Automatic startup and shutdown cycles reduce the need for skilled personnel. Alerts and remote communication modules allow centralized management.
Eco-Friendly Footprint: The by-product of the process is only hydrogen gas and dilute salt solution, which can be safely vented or diluted. No toxic by-products are discharged.

Frequently Asked Questions
1. Can this equipment use regular table salt?
Yes, the system accepts salt with NACL purity of at least 89%. However, for optimal performance and to protect the electrolytic cells, we recommend using high-purity salt (≥99%) without anti-caking agents or iodine.
2. What is the lifespan of the titanium anode?
With proper water and salt quality, the titanium anode typically lasts 5 to 8 years, depending on operating hours and current density. The system is designed to protect the cell from overheating and scale buildup.
3. Can the PLC control be integrated with our existing SCADA system?
Yes, our PLC supports common communication protocols such as RS-485, Modbus, and optional Ethernet. We can provide a detailed interface document for integration, and custom software is available upon request.
4. How much salt does the system consume per day?
Salt consumption varies with chlorine production rate. Approximately 1.6 – 2.0 kg of salt is needed to produce 1 kg of chlorine gas. For a dosing system of 5 kg/h, operating 12 hours a day, daily salt usage is around 100 kg.
5. Is the system fully automated? Do we need any skilled operators?
After the initial setup, the system runs fully automatically. The PLC manages all production and dosing parameters. It is recommended to have one operator check the system daily, but no specialized technical skills are required.
6. Does the equipment require frequent maintenance?
Maintenance is minimal. The electrolyzer cell needs to be cleaned periodically to remove scale if the water has high hardness. Also, the salt storage tank should be filtered to avoid impurities. Our user manual provides a simple maintenance schedule.
7. What safety measures are included?
The equipment is equipped with gas leak detection, low flow protection, high temperature cut-off, pressure relief valves, and automatic shutdown by the PLC in abnormal conditions. A manual emergency stop is also provided.
8. Can you provide customized production capacity above 50 kg/h?
Yes, we can design systems with larger electrolyzers and multiple units to produce up to 500 kg/h. Please share your detailed requirements, and our engineers will propose a suitable configuration.
