Benefits for Your Business
Reduce Operational Costs – By using low-purity salt (NaCl > 89%) instead of high-purity chemicals, you can cut raw material expenses by up to 40% without sacrificing performance.
Minimize Labor Requirements – The fully automatic system runs unattended, freeing your staff for other critical tasks. Remote monitoring and alerts are also available.
Environmental Compliance – On-site chlorine generation eliminates the need to transport, store, and handle hazardous chlorine gas cylinders, improving safety and reducing carbon footprint.
Consistent Water Quality – Precise dosing control maintains stable chlorine residual, preventing under- or over-chlorination that can cause health risks or equipment corrosion.
Scalable Solution – Modular design allows you to start with a small unit and easily add capacity as your demand grows, making it suitable for both small and large-scale applications.

Frequently Asked Questions (FAQ)
What type of salt can I use in this unit?
You can use any industrial salt with NaCl content greater than 89%. Common options include solar salt, rock salt, or vacuum salt. Avoid using salt with high impurities (e.g., calcium, magnesium) as they may affect cell performance.Does the unit require any additional chemicals?
No. The system only needs salt and water. It generates chlorine on-site through electrolysis, eliminating the need for purchasing and storing liquid chlorine or bleach.How often do I need to clean the electrolytic cell?
Cleaning frequency depends on water hardness and salt purity. Typically, the cell should be inspected every 3-6 months. The unit includes a self-cleaning function (optional) that reverses polarity to reduce scaling.Can I integrate this system with my existing SCADA or PLC?
Yes. Our dosing unit supports Modbus RTU, RS485, and optional 4-20mA output for seamless integration with most automation systems. Custom protocols are available upon request.What is the warranty period?
We offer a standard 12-month warranty from the date of shipment. Extended warranty options are available for purchase. The electrolytic cell is covered for 3 years against manufacturing defects.Is the unit suitable for seawater or brackish water?
Yes, but the salt purity requirement remains NaCl > 89%. If using seawater, additional filtration and pre-treatment may be needed to remove impurities. Our team can recommend the appropriate configuration.How long does installation take?
Installation typically takes 1-2 days for a standard unit. Our technical manual provides step-by-step guidance, and we offer remote or on-site commissioning support.What is the expected lifespan of the electrolytic cell?
Under normal operating conditions, the titanium electrode cell can last 5–8 years. Proper maintenance, such as periodic cleaning and avoiding over-voltage, can extend its life.
