Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. – a trusted manufacturer specializing in advanced electrochemical disinfection solutions. Our Fully Automatic Hypochlorite Acid Generator with PLC Control for Continuous Disinfection represents the latest innovation in on-site chlorine generation, designed to produce high-purity hypochlorous acid (HOCl) safely and efficiently. With over a decade of engineering experience and a global customer base spanning North America, Europe, Southeast Asia, Africa, and Oceania, ZLN delivers reliable, chemical-free disinfection systems that reduce operational costs and eliminate the risks of transporting and storing hazardous chemicals.
This generator uses a simple electrolysis process: a diluted salt solution passes through a patented electrolytic cell, producing hypochlorous acid – a powerful, eco-friendly disinfectant with broad-spectrum antimicrobial activity. The integrated PLC (Programmable Logic Controller) ensures fully automatic operation, real-time monitoring, and precise dosing, making it ideal for continuous disinfection in water treatment, food processing, healthcare, and industrial applications.
Key Features
PLC Control & Touch Screen HMI – User-friendly interface for setting production rate, monitoring pH, ORP, temperature, and receiving alarm notifications. The system can be integrated with SCADA or remote monitoring.
Continuous Operation – Designed for 24/7 production with automatic start/stop and self-cleaning cycles. No manual intervention required.
High Efficiency Electrolytic Cell – Uses titanium electrodes coated with mixed metal oxides (MMO) for long service life (up to 5 years) and low energy consumption.
Safe & Green – Produces hypochlorous acid on-site from salt, water, and electricity. No hazardous chlorine gas, no chemical storage, no transportation risks.
Compact & Modular Design – Skid-mounted or wall-mounted options available. Easy to install and maintain. Optional automatic descaling and cleaning system.
Low Maintenance – Self-cleaning electrode polarity reversal technology reduces scaling. Periodic salt refill and electrode inspection are the only routine tasks.

Advantages & Customer Benefits
Cost Savings – Eliminate expensive chemical purchases and logistics. Only common salt, water, and electricity are needed. Reduce total disinfection cost by up to 60% compared to traditional liquid chlorine or bleach.
Enhanced Safety – No hazardous chemical storage, no risk of chlorine gas leaks. The system operates at low voltage and includes multiple safety interlocks (over-temperature, over-current, low water flow).
Consistent Disinfection Quality – PLC maintains stable output concentration and pH. The produced hypochlorous acid is highly effective against bacteria, viruses, fungi, and biofilms.
Environmental Friendly – No chemical by-products except dilute brine. The process recycles water and minimizes waste. Green technology compliant with sustainable development goals.
Easy Operation & Remote Access – The HMI provides real-time data logging, historical trending, and alarm history. Optional remote monitoring via Ethernet or GSM module enables centralized control for multiple units.
Customizable Solutions – Available in different capacities, voltages, and configurations (skid, containerized, or mobile). We also offer automatic brine dissolving and dosing systems as add-ons.

Frequently Asked Questions
What is the difference between hypochlorous acid (HOCl) and sodium hypochlorite (NaOCl)?
Hypochlorous acid is a much stronger disinfectant with a higher oxidation potential. It is produced by electrolysis of salt water without any chemical additives. Unlike bleach, HOCl is non-irritating and safe for direct contact in low concentrations, making it ideal for food processing and healthcare.How long does the electrode last?
Our titanium MMO electrodes have a typical lifespan of 3–5 years, depending on water hardness and usage. The system includes automatic polarity reversal to reduce scaling, which extends electrode life.Do I need to buy special salt?
We recommend food-grade or high-purity salt (≥99.5% NaCl). Avoid iodized salt or salt with anti-caking agents, as they can damage the electrodes. Standard table salt is acceptable if it meets purity requirements.Can the generator run continuously?
Yes, it is designed for 24/7 continuous operation. The PLC automatically manages production cycles, self-cleaning, and standby mode. It can also be set to intermittent operation based on demand.What maintenance is required?
Routine maintenance includes checking salt level, inspecting electrodes every 6 months, and cleaning the tank if necessary. The self-cleaning function reduces manual work. We provide a detailed maintenance manual.What is the output concentration range?
Typically adjustable from 500 to 3000 ppm of free available chlorine (FAC) as HOCl. You can set the desired concentration via the HMI.Can I integrate this with my existing dosing pump?
Yes, the system can output a 4-20 mA signal to control an external dosing pump or proportional valve. We can also supply a complete dosing skid.What is the warranty period?
We offer a standard 12-month warranty for the entire system, with extended warranty options available. Electrodes are covered separately (typically 2 years). Please contact us for details.
