Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. As a trusted manufacturer with over a decade of experience in electrochemical water treatment solutions, we present our Skid Mounted HOCl Generation Unit—a compact, turnkey system designed specifically for water treatment plants requiring salt purity greater than 89%. This unit produces high-quality hypochlorous acid (HOCl) on-site through the electrolysis of brine, eliminating the hazards and costs associated with transporting and storing chlorine gas or bleach. Built with robust materials and advanced automation, our system ensures reliable disinfection performance, reduced chemical footprint, and simplified maintenance.
Key Features & Technical Specifications
Skid-Mounted Design: Factory-assembled on a heavy-duty steel frame, including all piping, wiring, and instrumentation—ready for quick on-site connection.
High-Efficiency Electrolytic Cells: Utilize titanium electrodes coated with mixed metal oxides (MMO), ensuring long service life (5+ years) and low energy consumption.
Variable Production Capacity: Available in models ranging from 0.5 kg Cl₂ equivalent/h up to 20 kg Cl₂/h; custom sizes available upon request.
Automatic Salt Dissolving & Brine Preparation: Built-in salt saturator with level sensors and automatic make-up to maintain optimal brine concentration.
PLC Control System: Programmable logic controller with color touch screen interface, allowing remote monitoring, data logging, and adjustment of production parameters.
Safety Features: Hydrogen gas dilution system, over-temperature protection, low water flow alarm, and emergency stop.
Low Operating Cost: Produces 1 kg of equivalent chlorine for approximately 3.5 kWh electricity and 3.2 kg of salt (purity >89%).
| Parameter | Value |
|---|---|
| Production capacity (Cl₂ equivalent) | 5 kg/h |
| HOCl concentration (as available chlorine) | 0.8% – 1.2% |
| Salt consumption | 16 kg/h (salt purity >89%) |
| Power consumption | 17.5 kW |
| Water flow rate (dilution) | 500 L/h |
| Dimensions (L×W×H) | 1800×1200×1600 mm |
| Weight | ~800 kg |
Why Choose ZLN Skid Mounted HOCl Generator? Our unit is engineered to meet the stringent requirements of modern water treatment plants. The exclusive use of high-purity salt (>89%) ensures maximum conversion efficiency and minimal by-product formation. The skid-mounted platform reduces installation time by up to 70% compared to traditional field-erected systems. Moreover, the automated PLC controller allows operators to precisely match disinfection demand, saving chemicals and energy.
Customer Benefits:
Enhanced Safety: Eliminates the need for hazardous chlorine gas cylinders or bulk bleach deliveries, reducing risk to personnel and the community.
Cost Savings: Lower chemical costs (salt vs. purchased chlorine) and reduced transportation/storage expenses.
Environmental Compliance: On-site generation minimizes chemical spills and reduces carbon footprint associated with transportation.
Operational Flexibility: Adjustable production rate from 25% to 100% of rated capacity, suitable for variable plant flow rates.

Frequently Asked Questions (FAQ)
Q1: What type of salt is required for this unit?
A: The unit is designed for food-grade sodium chloride (NaCl) with a purity greater than 89%. Avoid salt with anti-caking agents or high levels of calcium/magnesium as they may reduce efficiency.
Q2: How often do the electrodes need replacement?
A: With proper water quality and operation, the MMO-coated titanium electrodes typically last 5–7 years. We offer replacement cell stacks as spare parts.
Q3: What is the typical installation time?
A: Because the unit is pre-assembled and tested on a single skid, installation usually takes 1–2 days for electrical and piping connections. Detailed manual and drawing are provided.
Q4: Can the unit handle variable water flow rates?
A: Yes, the PLC controller allows adjustment of HOCl production from 25% to 100% of rated capacity. An optional flow-proportional control module can be integrated.
Q5: Is there a risk of hydrogen gas accumulation?
A: No, the system includes a built-in dilution fan and venting to keep hydrogen concentration well below the lower explosive limit (4% by volume). Safety certifications are available upon request.
Q6: What are the maintenance requirements?
A: Routine maintenance includes cleaning the salt saturator, checking electrode connections, and replacing the water filter. A preventive maintenance checklist is provided with the system.
Q7: Do you provide spare parts and technical support overseas?
A: Yes, we maintain a stock of common spare parts and offer email/phone support. Remote commissioning is available via WeChat/WhatsApp. Service engineers can visit on-site if needed.
Q8: How does this unit compare to traditional chlorine gas feeders?
A: On-site HOCl generation eliminates the need for pressurized chlorine containers, reduces chemical storage footprint, and is considered safer under current regulatory trends. Operating costs are often 30–50% lower than purchased bleach.
