As a leading manufacturer in Tianjin, China, Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is proud to introduce our PLC Controlled Liquid Chlorine Equipment. This advanced system is designed to provide automatic, safe, and cost-effective chlorine generation for various water treatment applications. With a strong emphasis on reducing salt and electricity consumption, our equipment delivers exceptional performance while lowering operational costs for your facility.
At ZLN, we combine engineering expertise with practical innovation to build equipment that meets the demanding needs of modern water treatment. Our PLC-controlled system ensures precise dosing, stable output, and minimal manual intervention, making it an ideal choice for municipal, commercial, and industrial water treatment projects. Every unit is manufactured using high-quality materials and rigorously tested to guarantee reliable operation in diverse conditions.
| Model | ZLN-LC Series |
| Control System | PLC-based, automatic feedback loop |
| Chlorine Output | 100 g/h – 20,000 g/h (customizable) |
| Salt Consumption | Optimized, lower than traditional systems |
| Electrical Consumption | Reduced, energy-efficient design |
| Material | PVC, titanium electrodes, corrosion-resistant |
| Operation | Touch-screen HMI, remote monitoring optional |
Our liquid chlorine equipment is engineered with a fully automatic PLC control system that continuously monitors and adjusts the chlorine generation process. This eliminates common problems such as overdosing or underdosing, ensuring consistent water quality while extending equipment lifespan. The intuitive touch-screen interface allows operators to set parameters easily, view real-time data, and receive alarms when maintenance is required.
Less Salt Consumption: The electrolytic cell design maximizes conversion efficiency, reducing salt usage by up to 15–20% compared to conventional generators. This directly lowers your chemical purchase costs and simplifies salt handling.
Less Electricity Consumption: Our advanced power conversion and optimized electrode spacing reduce power usage significantly. Field data show energy savings of up to 30%, making this an environmentally friendly and budget-friendly choice.
Automatic Operation: Once configured, the PLC runs the entire process without manual intervention. The system automatically controls brine concentration, water temperature, and chlorine output, so you can focus on other tasks.
Intelligent Safety Alarms: The PLC triggers alerts for low brine level, high temperature, or abnormal gas pressure, preventing potential damage and ensuring operator safety.
Corrosion-Resistant Structure: All wetted parts are made from durable PVC or titanium, guaranteeing long service life even in harsh chemical environments.
Dual-Purpose Application: Suitable for generating chlorine gas or sodium hypochlorite solution, depending on your specific disinfection needs.
The working principle of this liquid chlorine equipment is based on the electrolysis of brine solution. PLC controls the current density and flow rate, achieving an ideal balance between production rate and energy consumption. The modular design allows easy expansion when your water treatment capacity increases.
Pre-assembled and tested before delivery, reducing installation time and cost.
Low maintenance: easily cleanable electrodes with self-cleaning cycle option.
Compact footprint: occupies less floor space than traditional chlorine systems.
Environmentally safe: eliminates the risks associated with transporting and storing pressurized chlorine cylinders.
Compatible with both freshwater and seawater applications.

Frequently Asked Questions
1. What types of water can this equipment disinfect?
Our system is suitable for treating fresh water, wastewater, swimming pool water, cooling water, and marine water. It generates chlorine on-site and does not require transporting hazardous chemicals.
2. How much salt does it save compared with traditional systems?
Thanks to optimized electrode and current management, salt consumption is approximately 15–20% lower than conventional electrolyzers. Exact savings depend on water quality and output settings.
3. Is installation complicated?
No. The unit comes pre-assembled and skid-mounted. Your local electrician and plumber can connect it to power and water lines easily. We provide clear wiring diagrams and operation manuals in multiple languages.
4. What is the typical lifespan of the electrodes?
With proper maintenance and water quality, titanium electrodes typically last from 5 to 8 years. The system includes a polarity reversal function to prevent scaling and extend electrode life.
5. Can the PLC system connect to a SCADA or remote monitoring system?
Yes, we offer an optional Modbus or Ethernet interface so you can monitor chlorine output, alarms, and power consumption from a central control room or even via mobile devices.
6. How often does the system require maintenance?
Routine maintenance is minimal. We recommend checking the brine tank and cleaning the cell every 3 to 6 months, depending on hardness and salt quality. The PLC reminds you when cleaning is needed.
7. Does it need a special salt grade?
We recommend using high-purity salt (99% NaCl) for best results. Impurities may affect electrode life and chlorine production efficiency. Our system includes a brine filtration loop to remove particles.
8. What certificates does your equipment have?
Our manufacturing facility is certified. The equipment is designed in accordance with international electrical safety standards. If you require specific local certifications, please mention them when requesting a quotation.
