PLC Automatic and Skid Mounted Electrolytic Seawater Chlorination System With Low Power Consumption
Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. As a professional manufacturer with certification, we present our PLC Automatic and Skid Mounted Electrolytic Seawater Chlorination System designed for efficient, low-power disinfection. This system leverages advanced electrolysis technology to generate sodium hypochlorite directly from seawater, eliminating the need for chemical transportation and storage. It offers reliable, automated operation suitable for demanding industrial environments, ensuring continuous chlorination with minimal energy consumption.
Key Features & Technical Specifications
PLC Automatic Control: Fully automated operation with programmable logic controller, enabling remote monitoring, real-time parameter adjustment, and fault diagnosis. Reduces manual intervention and ensures consistent chlorine output.
Skid Mounted Design: Compact, pre-assembled unit mounted on a steel skid for easy installation, transportation, and maintenance. Ideal for offshore platforms, ships, and coastal facilities.
Low Power Consumption: Advanced electrode technology and optimized power supply achieve energy efficiency up to 30% lower than conventional systems. Typical power consumption per kg of chlorine: 3.5–4.5 kWh (depending on seawater temperature and salinity).
High Output Capacity: Available from 1 kg/h to 100 kg/h chlorine equivalent. Customizable to meet specific flow and dosage requirements.
Durable Materials: Electrodes made of titanium coated with mixed metal oxides (MMO), offering long service life and corrosion resistance. Housing and piping in PVC, UPVC, or FRP as per application.
Safety Features: Integrated hydrogen gas venting, automatic shutdown on abnormal conditions, and overcurrent protection.

Frequently Asked Questions (FAQ)
Q: What is the typical lifespan of the electrolytic cells?
A: Our MMO-coated titanium electrodes typically last 3–5 years under normal operating conditions, depending on seawater quality and duty cycle. Replacement is simple and cost-effective.Q: Can this system handle low-salinity seawater or brackish water?
A: Yes, the system can operate with seawater salinity as low as 8,000 ppm. For salinity below that, we recommend pre-concentration or consult our engineers for customization.Q: How do you control the chlorine dosage?
A: The PLC controller can receive a signal from a residual chlorine analyzer or flow meter to automatically adjust the electrolytic current, ensuring precise dosing. Manual adjustment is also possible.Q: Is hydrogen gas a safety concern?
A: We incorporate a dedicated hydrogen gas venting system with forced ventilation and auto-dilution to keep H2 concentration below the explosive limit. Gas detectors are optional for added safety.Q: What is the minimum space required for installation?
A: The skid footprint varies by model. For a 10 kg/h unit, allow approximately 4 m × 2 m area with 2.5 m headroom for maintenance access.Q: Do you provide installation guidance and training?
A: Yes, we offer on-site commissioning support and remote troubleshooting. Training for operators can be arranged as part of the purchase agreement.Q: What warranty do you offer?
A: We provide a standard 12-month warranty from the date of shipment, covering material and workmanship defects. Extended warranty options are available upon request.Q: Can the system be integrated with existing SCADA?
A: Absolutely. Our PLC supports common communication protocols such as Modbus RTU/TCP, Profibus, and Ethernet/IP for seamless integration.
