Sodium Hypochlorite Electrolyzer Fully Automatic Control Salt Purity Requirement NACL>89%
Product Spotlights
Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is a professional manufacturer specializing in advanced electrolysis systems. Our Sodium Hypochlorite Electrolyzer with Fully Automatic Control is designed to produce high-quality sodium hypochlorite on-site using only common salt, with a strict requirement of NaCl purity ≥ 89%. This system offers a reliable and cost-effective solution for disinfection needs across various industries.
With years of experience in electrochlorination technology, ZLN delivers equipment that combines efficiency, durability, and ease of operation. The fully automatic control system minimizes manual intervention, ensures consistent output, and reduces operational costs. Whether for municipal water treatment, swimming pool sanitation, or industrial wastewater disinfection, this electrolyzer is built to perform.
Key Features & Technical Specifications
Fully Automatic PLC Control: Touch-screen interface with real-time monitoring of production parameters (flow rate, temperature, concentration). Auto-start/stop, alarm functions, and remote communication capability (optional).
High-Efficiency Electrodes: Titanium-based MMO electrodes with long service life (typically 3-5 years) and low energy consumption. Designed for high salt tolerance and minimal scaling.
Salt Purity Requirement: NaCl ≥ 89% – works with standard industrial salt, no need for expensive high-purity salt. Salt consumption is optimized to reduce operating cost.
Compact Modular Design: Space-saving footprint, easy to install and maintain. Modules can be combined for larger production capacity.
Built-in Safety Features: Over-temperature protection, low-flow shutdown, hydrogen gas venting system, and leakage detection.
Adjustable Hypochlorite Concentration: Output concentration can be set from 3000 to 8000 ppm (as Cl2 equivalent) to meet different application requirements.
Low Maintenance: Automatic cleaning cycle using reverse polarity (optional) reduces manual descaling frequency.
| Parameter | Specification |
|---|---|
| Production Capacity (Cl2 equivalent) | 500 g/h, 1000 g/h, 2000 g/h (customizable) |
| Operating Voltage | DC 12V - 24V (depending on capacity) |
| Water Flow Rate | Variable, controlled by automatic valve |
| Ambient Temperature Range | 5°C - 45°C |
Operational Advantages
On-site Generation: Eliminates risks associated with transporting and storing hazardous chlorine gas or bulk sodium hypochlorite. Produces fresh disinfectant as needed, ensuring maximum efficacy.
Fully Automatic Control: Once set up, the system runs autonomously with minimal operator attention. The PLC maintains optimal electrolysis conditions, adapting to changes in water quality or flow.
Energy Efficient: Advanced power supply design with high conversion efficiency (>90%) reduces electricity costs. Optional solar-ready configuration for off-grid applications.
Cost-Effective: Using low-cost industrial salt (NaCl ≥ 89%) significantly reduces chemical expenses compared to purchasing commercial bleach. Payback period typically within 12-18 months for medium-scale users.
Environmentally Friendly: Only salt, water, and electricity are consumed. Byproducts are minimal and safe (dilute hydrogen gas is safely vented). No harmful chemical residues.
Typical Applications
Municipal drinking water disinfection
Wastewater treatment plant disinfection
Cooling tower water treatment (biofilm control)
Swimming pool and spa sanitation
Food processing plant sanitation
Agricultural irrigation water treatment
Marine and offshore platform disinfection
Frequently Asked Questions
What is the minimum salt purity required? The system is designed for NaCl ≥ 89%. Salt with lower purity may cause reduced efficiency and increased scaling. We recommend using standard industrial salt meeting this specification.
How often do I need to replace the electrodes? With proper maintenance, the MMO electrodes typically last 3-5 years depending on operating conditions. Automatic reverse polarity cleaning can extend electrode life.
Can the system be integrated with existing SCADA? Yes, the PLC can be equipped with Modbus/RS485 communication (optional) for remote monitoring and control.
What is the typical production cost per liter of sodium hypochlorite? Assuming salt price of $0.1/kg and electricity $0.1/kWh, the cost is approximately $0.02-0.03 per liter of 0.5% active chlorine solution.
Does the system require a dedicated water softener? Not necessarily, but if feed water hardness is high (>300 ppm), a pre-treatment softener is recommended to reduce scaling in the electrolytic cell.
What safety measures are included? The unit features automatic shutdown on high temperature, low flow, and hydrogen gas detection. It also includes a pressure relief valve and ventilation fan (optional).
Can I tailor the production capacity to my needs? Absolutely. We offer modular designs from 100 g/h up to 10,000 g/h. Custom configurations are available upon request.
How long does it take to install and commission? Typically 1-2 days for a standard unit. Our team provides remote guidance or on-site commissioning (travel costs extra).
