Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. proudly presents our advanced Electrolytic Seawater Chlorination System, specifically engineered to meet the rigorous demands of marine and offshore applications. As a reputable manufacturer with certification, we combine years of expertise with cutting-edge PLC control technology to deliver a reliable, efficient, and fully customizable solution for generating sodium hypochlorite directly from seawater. Our system supports all major electrode configurations — PPE, CTE, and MESH — allowing you to select the optimal design based on your seawater quality, capacity requirements, and maintenance preferences.
This system is designed for long-term operation in harsh marine environments, providing consistent chlorination to prevent biofouling in cooling water systems, ballast water treatment, and various industrial processes. With a PLC-based intelligent control interface, operators can easily monitor and adjust parameters such as flow rate, current density, and chlorine production level. The combination of robust construction, advanced control, and flexible electrode options makes ZLN's chlorination system a top choice for ship owners, offshore platforms, and coastal facilities worldwide.
Key Features & Technical Specifications
Electrode Options: Choose from PPE (Platinized Platinum Electrode), CTE (Ceramic Titanium Electrode), or MESH (Mixed Metal Oxide Mesh Electrode). Each technology offers distinct advantages in terms of durability, energy efficiency, and chlorine output stability.
PLC Control System: Equipped with a user-friendly PLC touch screen interface, enabling real-time monitoring of operating parameters, automatic adjustment of current and flow, and remote communication via optional modules.
High Conversion Efficiency: Optimized cell design ensures efficient electrolysis of seawater, minimizing power consumption while maintaining consistent hypochlorite concentration (up to 0.8–1.2% as Cl₂).
Corrosion Resistance: All wetted parts are constructed from titanium, super-duplex stainless steel, and high-grade polymer materials, ensuring longevity even in saline and aggressive environments.
Modular & Compact Design: Available in skid-mounted or containerized configurations to fit limited space aboard vessels or onshore installations. Capacity ranges from 0.5 kg/h to 50 kg/h of equivalent chlorine, with larger systems available upon request.
Safety Features: Integrated hydrogen gas venting, automatic shutdown on fault conditions, over-temperature protection, and low-flow alarm ensure safe and reliable operation.

Frequently Asked Questions (FAQ)
Q: What are the differences between PPE, CTE, and MESH electrodes?
A: PPE (Platinized Platinum Electrode) offers high stability in dirty seawater but has a moderate lifespan. CTE (Ceramic Titanium Electrode) provides excellent corrosion resistance and is cost-effective. MESH (Mixed Metal Oxide Mesh) electrodes have the longest lifespan and highest efficiency, ideal for continuous high-load operation. We help you choose based on your water quality and budget.Q: Does the system require any pre-treatment of seawater?
A: For optimal performance, we recommend installing a simple sand filter or strainer to remove large particles and marine debris. The system includes an internal self-cleaning mechanism for the electrolytic cell, reducing the need for extensive pre-treatment.Q: Can the PLC control be integrated with remote monitoring?
A: Yes, our PLC can be equipped with optional 4G, Wi-Fi, or MODBUS communication modules for remote monitoring and control via a smartphone or central control room.Q: What is the typical lifespan of the electrolytic cell?
A: Depending on operating conditions and electrode type, the expected lifespan is 5–8 years for MESH, 3–5 years for CTE, and 2–4 years for PPE. Regular maintenance (e.g., acid cleaning) can extend service life.Q: Is the system compliant with IMO Ballast Water Management Convention?
A: Yes, our system can be configured to meet IMO D-2 discharge standards and USCG type approval can be applied upon request. Please contact our sales team for details.Q: Do you provide installation and commissioning services?
A: We provide on-site installation and commissioning support at an additional cost, or we offer detailed manuals and remote guidance via video call. Our technical team is available 24/7.Q: What is the typical delivery time?
A: Standard systems are shipped within 30–45 days after order confirmation. Customized systems may take 60–90 days depending on complexity. We ship from Tianjin Port.Q: How do I decide the required capacity for my application?
A: Our engineers will perform a free water analysis and system sizing based on your flow rate, chlorine demand, and operating hours. Simply provide us with your requirements and we will recommend the optimal model.
