Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. – your trusted manufacturer of advanced seawater electrolysis chlorination systems. Our PLC Automatic and Skid Mounted Design Seawater Electrolysis Chlorination System with Low Power Consumption is engineered to deliver a reliable, continuous supply of chlorine for marine and industrial applications while minimizing energy costs. Built on years of expertise in electrochemical water treatment, ZLN’s system integrates intelligent PLC control, compact skid mounting, and optimized titanium electrodes to achieve outstanding efficiency. Whether you need to protect seawater cooling pipes from biofouling or treat ballast water, this system offers a cost-effective, environmentally friendly solution that meets the highest operational standards.

Key Features & Technical Specifications

  • PLC Automatic Control: Equipped with a Siemens or Allen-Bradley PLC and HMI touch screen, the system automatically adjusts production rate based on water flow, salinity, and temperature. No manual intervention required – just set and forget.

  • Skid Mounted Design: All components (electrolyzer, rectifier, control panel, pumps, and piping) are pre-assembled on a robust steel skid. This reduces installation time and footprint, making it ideal for offshore platforms, ships, and coastal plants.

  • Low Power Consumption: Advanced DSA (Dimensionally Stable Anode) titanium electrodes coated with mixed metal oxides achieve high current efficiency (>85%). Typical power consumption is ≤4.5 kWh per kg of chlorine equivalent, significantly lower than traditional systems.

  • Seawater Electrolysis Technology: Directly converts seawater (without pre-treatment) into sodium hypochlorite (NaClO) through electrolysis. The generated hypochlorite is a powerful biocide for bacteria, algae, and marine organisms.

  • Corrosion-Resistant Materials: Electrolyzer body made of FRP or PVC, with titanium electrodes that resist seawater corrosion. All wetted parts are designed for long service life in harsh marine environments.

  • Modular & Scalable: Available in capacities from 1 kg/h to 100 kg/h Cl2 equivalent. Multiple units can be paralleled for higher demands.

  • Low Maintenance: Self-cleaning electrode polarity reversal (optional) and automatic acid washing (optional) reduce scaling and ensure consistent performance.

  • Safety Features: Built-in hydrogen venting, over-temperature protection, low-flow alarm, and leak detection for safe operation.

Benefits to Your Operation

  • Energy Savings: With power consumption as low as 4.5 kWh/kg Cl2, you can cut electricity costs by up to 30% compared to conventional systems.

  • Space Efficiency: The skid-mounted design reduces on-site installation work – just connect seawater, power, and dosing lines. Ideal for retrofits or new builds with limited space.

  • Automation & Reliability: PLC control ensures stable chlorine output regardless of seawater salinity changes. Remote monitoring and alarm functions allow 24/7 unattended operation.

  • Environmentally Friendly: No transport or storage of hazardous chemicals (chlorine gas or bleach). Hypochlorite is produced on-site from seawater, reducing safety risks and environmental footprint.

  • Extended Equipment Life: High-quality titanium electrodes have a lifespan of 5–8 years under normal operation. The system’s self-cleaning options further reduce scaling and maintenance.

Frequently Asked Questions (FAQ)

  • Q: What is the typical power consumption of this system?
    A: Our system consumes ≤4.5 kWh per kilogram of chlorine equivalent, which is among the lowest in the industry. Actual consumption may vary slightly depending on seawater temperature and salinity.

  • Q: Can the system handle varying seawater salinity (e.g., brackish water)?
    A: Yes, the PLC automatically adjusts current density based on the salinity sensor reading. The system is designed for seawater (salinity 18–35 ppt), but can be adapted for lower salinity with consultation.

  • Q: How often do the electrodes need replacement?
    A: With proper maintenance, the titanium electrodes last 5–8 years. We recommend an annual inspection; the system can be equipped with a runtime counter to track electrode usage.

  • Q: Is the skid mounted design suitable for offshore platforms?
    A: Absolutely. The skid is fabricated from marine-grade steel with anti-corrosion coating. Compact footprint and modular design make it ideal for offshore environments with limited space.

  • Q: Do you provide certification like CE or ATEX?
    A: We can provide certification upon request for specific markets. Standard systems are designed to meet international safety norms; please contact us with your requirements.

  • Q: What is the lead time for delivery?
    A: Typical lead time is 30–45 days after order confirmation, depending on capacity and customization. We ship from Tianjin Port, China.

  • Q: Can the system be integrated with existing SCADA or DCS?
    A: Yes, the PLC supports Modbus RTU/TCP protocol for remote monitoring and control. Integration with your existing control system can be arranged.

  • Q: What maintenance is required?
    A: Regular maintenance includes checking the rectifier, cleaning the electrode surface (if scale buildup observed), and verifying safety devices. Optional automatic acid washing minimizes manual cleaning.
