Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd is proud to introduce our Fully Automatic Liquid Chlorine Dosing System with PLC Control and Skid Mounted Plug-Play Design. As a professional manufacturer located in Tianjin, China, we focus on delivering reliable and efficient water treatment solutions. This dosing system is engineered to provide precise chemical injection for disinfection and water quality control, ensuring consistent performance even in demanding environments. With a plug-play skid design, installation is quick and hassle-free, making it an ideal choice for municipal water plants, industrial processes, and swimming pools worldwide.
Product Features & Benefits
Fully Automatic Operation: The PLC-based control system automatically adjusts dosing rates based on real-time flow or residual chlorine signals, eliminating manual intervention and reducing labor costs.
Skid-Mounted Plug-Play Design: All components (pump, controller, piping, valves) are pre-assembled on a sturdy skid. Simply connect inlet/outlet and power, and the system is ready to run.
High Precision Dosing: Using a diaphragm metering pump or peristaltic pump, the system delivers accurate chlorine dosage from 0.5 L/h up to 500 L/h, with ±1% repeatability.
Robust Material Options: Parts in contact with liquid chlorine are made of corrosion-resistant materials such as PVC, PP, or stainless steel 316 to ensure long service life.
Intuitive HMI Touchscreen: The PLC controller comes with a user-friendly HMI display for setting parameters, monitoring status, and viewing historical data.
Fail-Safe Safety Features: Includes low-level alarm, leakage detection, and emergency stop functions to ensure operator safety.
Low Maintenance: Modular design with easy-access parts simplifies servicing and reduces downtime.

A: Yes, the PLC supports MODBUS RTU/TCP communications (RS485 or Ethernet). Integration with your facility’s monitoring system is straightforward.Q: What materials are used for wetted parts?
A: Standard wetted parts are PVC/PP; for higher temperature or aggressive chemicals, 316L stainless steel or PVDF is available as an upgrade.Q: How do I determine the correct dosing capacity for my application?
A: We need the water flow rate (m³/h) and the desired chlorine residual. Our sales engineer will provide a sizing calculation based on your parameters. Contact us for a free evaluation.Q: Is the system safe if there is a chlorine leak?
A: Absolutely. The system is equipped with a chlorine gas detector (optional) and automatic shutdown valve. The skid also has a containment basin to prevent spills.Q: What is the warranty period?
A: Standard warranty is 12 months from shipment. Extended warranty up to 36 months is available upon request.Q: Can I get a system for a very small flow rate, e.g., 0.1 L/h?
A: Yes, we have a mini series capable of dosing from 0.02 L/h. However, the standard model range starts at 0.5 L/h. Customization for lower flows is possible.Q: Do you provide spare parts and technical documentation?
A: Yes, we supply a complete spare parts list, user manual, wiring diagram, and PLC program backup. Local distributors in many regions stock common spare parts.
