Product Advantages
Precision Dosing: The PLC control system maintains a stable chlorine concentration within ±1% of setpoint, ensuring effective disinfection without over-chlorination.
Fully Automatic Operation: Once configured, the system runs unattended – it automatically adjusts dosing based on flow rate or residual chlorine feedback (optional sensor).
User-Friendly Interface: The HMI touch screen provides real-time data, alarm logs, and easy parameter modification. No specialized programming skills required.
Flexible Concentration: Handles liquid chlorine concentrations from 5% to 15%, allowing you to use standard sodium hypochlorite or custom solutions.
Robust Construction: All wetted parts are made of corrosion-resistant PVC/UPVC/PP, ensuring long service life even in harsh chemical environments.
Compact & Modular Design: Skid-mounted for easy installation and integration – saves floor space and reduces on-site piping work.
Technical Benefits for Your Business
By investing in our liquid chlorine dosing system, you gain:
Reduced Chemical Consumption: Automatic control avoids overfeeding, saving up to 20% on chemical costs compared to manual dosing.
Improved Safety: Enclosed piping and remote monitoring minimize operator exposure to chlorine fumes and liquid spills.
Consistent Water Quality: Stable residual chlorine levels prevent bacterial regrowth and meet regulatory standards (e.g., WHO, EPA guidelines).
Lower Maintenance: Self-cleaning filters and easy-access pump heads reduce downtime. PLC diagnostics alert you before issues escalate.

Frequently Asked Questions (FAQ)
Q1: What types of liquid chlorine can be used with this system?
A: The system is designed for sodium hypochlorite (NaClO) solutions with concentrations between 5% and 15%. It can also handle other chlorine-based disinfectants after proper material compatibility check.
Q2: Does the system come with a tank? What size?
A: The dosing system is typically supplied without a storage tank, but we can customize a skid with a tank (e.g., 200L, 500L, 1000L) based on your needs. Please specify your requirement when ordering.
Q3: How do I set the desired chlorine concentration?
A: Through the PLC HMI touch screen, you can enter the target concentration in %. The system automatically adjusts the dosing pump speed or stroke length to maintain that level.
Q4: Is remote monitoring or SCADA integration possible?
A: Yes, the PLC supports Modbus RTU/TCP communication. We can integrate with your existing SCADA system or provide a remote monitoring module (optional).
Q5: What power supply does the system require?
A: Standard power options are 220V/50Hz single-phase or 380V/50Hz three-phase. Other voltages (110V, 415V, 60Hz) are available upon request. Please confirm your local power supply when inquiring.
Q6: How often should calibration be performed?
A: The flow sensors and chlorine analyzers (if installed) should be calibrated every 6 months for optimal accuracy. The PLC control itself does not require calibration.
Q7: What is the warranty period?
A: We offer a 12-month warranty from the date of shipment covering manufacturing defects. Extended warranties are available as an optional service.
Q8: Can the system handle variable flow rates in the main water line?
A: Yes, the PLC can be connected to a flow meter on the main line and automatically proportion the chlorine dosing. This is a standard feature for our automatic models.
Note: Specifications may vary based on customization. For detailed technical drawings and a quote, please contact our sales team.
