he core principle relies on brine electrolysis:
A 3–5% saltwater solution is pumped into an electrolytic cell with titanium electrodes (coated in ruthenium/iridium for corrosion resistance).
Electrolysis splits chloride ions (Cl⁻) and water molecules, generating chlorine gas (Cl₂) at the anode and hydroxide ions (OH⁻) at the cathode.
Chlorine gas reacts with hydroxide ions to form sodium hypochlorite (NaClO), with hydrogen gas (H₂) as a byproduct (safely vented or diluted to non-explosive levels).
Modular & Compact Design
Scalable units (10–500 g/h chlorine output) with a space-saving footprint (0.5–3 m²), ideal for small to medium-sized facilities.
Plug-and-play structure: Pre-assembled components (electrolytic cell, brine mixer, control panel) allow quick installation (typically 1–2 days).
Advanced Electrolytic Cell
Bipolar electrode configuration reduces energy consumption (≤4.2 kWh/kg Cl₂) and extends electrode lifespan (anodes: 5+ years; cathodes: 15+ years).
Membrane-free or low-cost diaphragm technology (depending on model) minimizes maintenance and ensures stable NaClO concentration (5,000–8,000 ppm).
Automated Operation
PLC-based control system with a touchscreen interface for real-time monitoring (salt levels, chlorine output, power usage).
Auto-adjustment of brine flow and current to maintain consistent concentration; self-cleaning cycles (acid flushes) prevent electrode scaling.
Enhanced Safety Systems
Hydrogen gas monitoring: Built-in sensors trigger alarms if H₂ levels exceed 1% (explosive limit: 4%), with automatic ventilation activation.
Leak-proof casing (epoxy-coated steel) and emergency shutdown protocols (power failure, brine shortage) to prevent spills.
Flexible Output
Adjustable concentration (5,000–12,000 ppm) via control panel, suitable for diverse disinfection needs (e.g., 5,000 ppm for drinking water, 10,000 ppm for industrial sanitation).

FAQ:
1: How often does the unit require maintenance?
Routine maintenance includes monthly salt tank refills, quarterly filter replacements (to remove sediment), and annual acid cleaning of electrodes. The control system sends alerts for scheduled checks, and electrodes typically last 5+ years before replacement.
2: Can the unit operate with hard water?
Hard water (high calcium/magnesium) may cause scaling on electrodes. We recommend pairing the unit with a water softener or pre-filtration system (included in premium models) to extend electrode life and ensure stable performance.
3: What is the output concentration range, and can it be adjusted?
The standard range is 5,000–8,000 ppm, but most models allow adjustment via the control panel (e.g., 5,000 ppm for drinking water, 10,000 ppm for heavy-duty disinfection). Higher concentrations (up to 12,000 ppm) are available in industrial-grade units.
