Industrial Seawater Electrolysis Systems
Century is a premier manufacturer of heavy-duty seawater electrolysis systems engineered specifically for marine, offshore, and coastal industrial applications. By leveraging the natural salinity found in ocean water (typically containing 19% to 25% sodium chloride equivalent), our direct electrolysis technology generates a highly effective active chlorine solution (including HClO, ClO⁻, and Cl₂) directly on-site.
Operating as a robust seawater hypochlorite generator, this equipment completely eliminates the need to purchase, transport, or store industrial salt or hazardous commercial bleach. Our systems are designed for continuous, high-volume operation, providing a continuous stream of potent disinfectant to neutralize marine biological threats, algae, and bacteria in critical infrastructure. Whether you are operating a coastal power plant or outfitting a commercial vessel, Century delivers factory-direct electrochlorination solutions tailored to your exact volumetric demands.
Why Choose Century Seawater Electrolysis Equipment?
Upgrading your facility with our direct seawater electrochlorination technology provides immediate operational and financial advantages:
- Zero Raw Material Costs: Because the system directly utilizes intake seawater, the ongoing operational expenditure (OPEX) for purchasing industrial salt is entirely eliminated. Your only inputs are natural seawater and standard electrical power.
- Maximum Site Safety: Facilities and ships no longer need to maintain large storage tanks of highly volatile, concentrated chemical oxidants. Generating hypochlorite on demand significantly reduces the risk of hazardous spills and simplifies Process Safety Management (PSM) compliance.
- Premium Anode Construction: At the heart of every unit is an advanced anti-fouling electrolysis cell featuring pure titanium anodes coated with our proprietary Ruthenium-Iridium (Ru-Ir) oxide. This specialized coating guarantees superior electrochemical efficiency and an extended lifespan even in harsh marine environments.
- Intelligent & Flexible Controls: We build systems to match your operational preferences. Units can be configured with highly cost-effective manual valve controls and current adjustments, or fully automated PLC integration featuring single-button start protocols and automatic reverse-polarity to mitigate calcium scaling .
System Configurations & Product Lines
We engineer our seawater electrolysis units into two primary architectures to accommodate different spatial footprints and chlorine yield requirements.
[Category 1: Integrated Skid-Mounted Systems (HSE 100G – 1K)]
Designed for environments with limited space, such as offshore platforms or smaller pump stations. These integrated units house the rectifiers, control modules, and electrolysis cells on a single, compact skid.
- Capacities: 0.1 kg/h up to 1.0 kg/h active chlorine yield.
- Key Benefit: Plug-and-play installation, reducing on-site engineering time.
[Category 2: Split-Type High-Capacity Systems (HSE 2K – 6K)]
Engineered for heavy industrial applications requiring massive volumes of continuous disinfection. The power supply centers and the larger electrolyser vessels are separated to optimize heat dissipation and accommodate extensive piping layouts.
- Capacities: 2.0 kg/h up to 6.0+ kg/h active chlorine yield.
- Key Benefit: Scalable output capable of supporting massive intake volumes for cooling towers and large vessel ballast tanks.
Primary Industrial Applications
Century’s equipment is currently supporting industrial distributors and end-users across the United States, Spain, and Venezuela. Our systems are purpose-built for the following critical sectors:
- Coastal Power Plants & Petrochemical Facilities: Chemical plants and power generation facilities require massive amounts of water for cooling. Using coastal seawater is highly economical, but marine microorganisms quickly attach and breed within cooling pipelines. Deploying electrochlorination for cooling towers ensures a steady dose of hypochlorite that kills these organisms, preventing pipeline narrowing, blockages, and severe drops in heat exchange efficiency.
- Marine Ballast Water Treatment: Commercial vessels can safely prepare sodium hypochlorite by electrolyzing seawater directly onboard, ensuring regulatory compliance without storing bulk chemicals. The generated solution is injected into the ballast tanks to effectively eradicate invasive marine life, algae, and pathogens, ensuring the ballast water can be safely discharged at the destination port.
Technical Specifications (HSE Series)
To guarantee optimal efficiency and prevent premature electrode degradation, all intake seawater must be properly filtered prior to entering the electrolysis cell to remove large suspended solids and debris. Below are the standard technical parameters for our HSE product line:
| Model Series | System Architecture | Raw Material Input | Active Chlorine Yield (kg/h) | Power Consumption (kW/h) |
|---|---|---|---|---|
| HSE-100G | Integrated System | Natural Seawater | 0.1 | 2.0 |
| HSE-200G | Integrated System | Natural Seawater | 0.2 | 2.0 |
| HSE-300G | Integrated System | Natural Seawater | 0.3 | 2.0 |
| HSE-500G | Integrated System | Natural Seawater | 0.5 | 2.0 |
| HSE-1K | Integrated System | Natural Seawater | 1.0 | 4.0 |
| HSE-2K | Split-Type System | Natural Seawater | 2.0 | 8.0 |
| HSE-3K | Split-Type System | Natural Seawater | 3.0 | 12.0 |
| HSE-4K | Split-Type System | Natural Seawater | 4.0 | 16.0 |
| HSE-5K | Split-Type System | Natural Seawater | 5.0 | 20.0 |
| HSE-6K | Split-Type System | Natural Seawater | 6.0 | 24.0 |
Note: Data reflects standard configurations. All systems produce an effective chlorine concentration of 8,000-9,000 ppm and come with a standard 2-year warranty. Custom OEM capacities exceeding 6.0 kg/h are available upon engineering request.
Rigorous QA & Custom Retrofit Capabilities
As a direct manufacturer, Century exercises absolute control over the production of our titanium anode plates and power centers. If you are operating an aging system from another manufacturer, we provide seamless drop-in replacements for your existing equipment to drastically minimize downtime. Every complete system and component undergoes comprehensive testing and strict quality assurance before shipment.
Frequently Asked Questions (FAQs)
No. As long as your facility utilizes coastal seawater with a natural salinity range of 19% to 25%, the system requires zero additional industrial salt.
Our systems can be equipped with an automatic reverse-polarity function that significantly minimizes calcium and magnesium scaling on the electrodes. However, routine visual inspections and occasional acid washing may be required depending on your local seawater hardness.
Yes. We specialize in B2B custom manufacturing. Our engineering team can adjust the layout of the electrolyser vessels, rectifiers, and piping to perfectly match your specific facility footprint and intake configurations.
