Below we outline the key technical features, benefits, and frequently asked questions to help you understand why ZLN liquid chlorine equipment is a trusted partner for your operations.
Product Features & Technical Specifications
Our fully automatic liquid chlorine equipment is manufactured with high-grade materials and precision components, ensuring long service life and consistent output. The system is pre-piped, pre-wired, and factory-tested, so installation is straightforward and commissioning is fast.
Fully Automatic Control: Uses a PLC-based control system with a touch-screen HMI. The system automatically adjusts chlorine feed rate based on flow proportional or chlorine residual signals, eliminating manual dosing errors.
Safe Vaporization: Equipped with a chlorine evaporator bath that provides controlled heat input, ensuring liquid chlorine is reliably converted to gas without over-pressurization. Double temperature and pressure sensors continuously monitor system safety.
High Corrosion Resistance: Wetted parts are made of SS316L, PTFE, PP, and PVDF, which withstand the aggressive nature of wet chlorine gas and hypochlorite solutions.
Flow Proportional Dosing: The dosing pump and control valve modulate automatically according to the main flow signal, maintaining a stable chlorine concentration under varying water flow conditions.
Alarm & Safety Interlock: Includes high-temperature, low-temperature, high-pressure, low-pressure, gas leak, and power failure alarms. The system automatically shuts off chlorine gas flow if any abnormal condition occurs.
User-friendly Interface: Multilingual HMI displays real-time process variables, alarm logs, and dosing trends. Remote monitoring and SCADA integration are available on request.
Compact Design: Skid-mounted configuration saves floor space and simplifies maintenance. All key components are easily accessible.

Key Benefits for Your Plant
Precise Dosing: Maintains chlorine residual within ±0.1 ppm, even when flow rate changes rapidly. This ensures effective disinfection while minimizing chemical waste.
Lower Operating Costs: Automatic control reduces chlorine over-dosing and saves energy. The efficient vaporizer design lowers heating costs by up to 15% compared to conventional systems.
Enhanced Safety: Multiple redundant safety features protect your operators and facility. The gas leak detector and automatic shut-off mechanism respond instantly to prevent chlorine release.
Rapid ROI: Reduced manual labor and chemical waste typically deliver payback within 12–18 months for a standard municipal plant.
Easy Integration: The equipment is compatible with existing flow meters, residual analyzers, SCADA systems, and PLC networks. We provide digital I/O and analog signal interfaces as standard.
Customizable Configuration: Different capacities, heating methods, control valves, and communication protocols are available upon request. Our engineers will tailor the system to your specific site conditions.
The fully automatic liquid chlorine equipment is suitable for a wide range of industries, including drinking water treatment plants, wastewater treatment facilities, swimming pools, industrial cooling water systems, pulp & paper bleaching, and chemical processing. It is designed to meet the demanding requirements of continuous operation in harsh environments.

FAQ
Q: What is the difference between liquid chlorine dosing and vacuum gas feeding?
The ZLN system first vaporizes liquid chlorine into gas, then feeds the gas under a vacuum or constant pressure ejector system. This provides precise measurement and prevents liquid chlorine from entering the process directly, which is safer and more stable.
Q: Do you provide installation assistance?
Yes. We provide detailed installation drawings, video tutorials, and remote guidance. If required, our engineers can visit your site for commissioning and training; travel costs are quoted separately.
Q: Can the capacity be customized?
Absolutely. The standard range covers 0.5 to 5 kg/h. Capacities up to 50 kg/h or multiple skids in parallel are available upon request. We will calculate the required chlorine dosage based on your water flow and chlorine demand.
Q: What power supply is required?
Standard units accept 220V/380V, 50/60Hz. We can also design for 110V, 230V, or 660V systems, and UPS backup power is optional.
Q: How long does the system take to heat up?
Typical warm-up time from cold start to operating temperature is 15–30 minutes, depending on ambient temperature and heating power. The system maintains a constant bath temperature using an automatic controller.
Q: Does the system have a remote monitoring function?
Yes, the HMI supports remote monitoring protocols including Modbus TCP/RTU. It can connect to your SCADA or DCS, and optional 4G/WiFi modules enable remote access via mobile phone.
Q: What spare parts do you recommend keeping in stock?
Standard recommended spares include a set of gaskets, a pressure relief valve, a chlorine gas filter element, and an HMI power supply. A detailed spare parts list is provided with the operational manual.
Q: What is the lead time and shipping port?
For standard models, the production lead time is 15–30 days. We ship from Tianjin Port, China, and can arrange sea freight, air freight, or express delivery according to your requirements.
