Titanium Anode for Swimming Pool Sodium Hypochlorite Generator
In the field of swimming pool water disinfection, sodium hypochlorite generators produce chlorine online by electrolyzing dilute brine, providing continuous and stable disinfection for pool water quality. Our Titanium Anode for Swimming Pool Sodium Hypochlorite Generator at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for the core electrolysis assembly of commercial and residential swimming pool sodium hypochlorite generators. It uses Grade 1 or Grade 2 pure titanium as the substrate, with a ruthenium-iridium mixed metal oxide catalytic coating on the surface. The ruthenium component imparts a very low chlorine evolution overpotential to the coating in dilute brine, enabling efficient active chlorine generation with low energy consumption. The introduction of the iridium component enhances the structural stability of the coating during the accompanying oxygen evolution side reaction, allowing the anode to maintain a long service cycle under intermittent operation and fluctuating water quality conditions, providing continuous and stable disinfection for swimming pools.
This product is for B2B industrial and commercial equipment use only. Operators should follow relevant chemical safety protocols and electrolysis operation standards.

Why Choose Our Titanium Anodes?
- Efficient Chlorine Evolution in Dilute Brine for Reduced Operating Costs
Swimming pool sodium hypochlorite generators typically use dilute brine at a concentration of 3–5% as the electrolysis feedstock. Our ruthenium-iridium coating exhibits a very low chlorine evolution overpotential under low-concentration brine conditions, enabling efficient active chlorine generation at low cell voltage. For commercial swimming pool disinfection systems requiring extended daily operation, lower energy consumption translates to reduced electricity costs and equipment heating, contributing to extended generator service life. - Coating Durability Under Intermittent Operation
Swimming pool sodium hypochlorite generators typically start and stop intermittently based on water quality monitoring signals, with the anode operating under frequent electrolysis-immersion cycling conditions. Our ruthenium-iridium coating formulation is optimized to resist passivation or spalling under frequent start-stop cycles and fluctuating water quality conditions, maintaining a low coating consumption rate suitable for long-term stable operation of swimming pool disinfection systems. - Clean and Safe Chlorine Generation Material System
The coating and titanium substrate maintain a stable chemical state during electrolysis, with minimal dissolution of heavy metals or other harmful impurities into the disinfectant solution. For swimming pool water that comes into direct contact with human skin and mucous membranes, this material system helps maintain the hygienic safety of pool water quality and avoids the risk of secondary contamination. - Flexible Customization for Different Generator Specifications
We can supply plate, mesh, tubular, and rod anodes, compatible with the electrolytic cells of residential salt chlorinators, commercial medium-capacity sodium hypochlorite generators, and large-scale swimming pool disinfection systems. Based on your generator specifications, cell structure, and chlorine output requirements, anode dimensions, shapes, and conductive connection methods can be customized for convenient integration with existing equipment.

The ShenAo Advantage
18 Years of Fabricating Excellence
Since 2008, we've specialized in valuable metal coated titanium anodes from our office in Baoji's "China Titanium Valley." Our develop bimetallic hazardous welding innovation and progressed coating forms provide items you can trust.
Customization for Your Correct Needs
Every generation line is diverse. We give custom fitted arrangements coordinating your particular current thickness necessities, electrolyte composition, and operational parameters. Whether you require little bunch testing or full-scale generation amounts, we convey on time.
Cost-Effective Lifecycle Management
When coating exhaustion happens, you do not dispose of the whole anode. Our proficient recoating benefit strips the ancient oxide layer, sandblasts the substrate, and reapplies new MMO coating. This expands resource life and decreases your add up to taken a toll of proprietorship considerably.
Frequently Asked Questions
Q: What is the expected service life of anodes for swimming pool sodium hypochlorite generators?
A: Under normal operating conditions, ruthenium-iridium coated anodes typically have a design life of 3–5 years or longer, depending on operating current density, brine concentration, water hardness, and daily operating hours. When water hardness is high, calcium and magnesium scale may form on the anode surface. Periodic cleaning with dilute acid is recommended to maintain electrolysis efficiency. Using high-purity salt and soft water to prepare brine can extend anode service life.
Q: How should white deposits on the anode surface be addressed?
A: White deposits are primarily calcium carbonate and magnesium hydroxide scale, originating from calcium and magnesium ions in salt and tap water. It is recommended to periodically remove the anode from the electrolytic cell, soak and clean it with diluted hydrochloric acid or acetic acid solution, and then rinse thoroughly with clean water. Using deionized or softened water to prepare brine can slow scale formation.
Q: How can I determine whether the anode coating needs replacement?
A: Two key indicators should be monitored: first, a noticeable decline in chlorine output, where the rated available chlorine concentration cannot be reached even when the current is increased; second, a sustained increase in cell voltage with no improvement after cleaning. We recommend establishing a periodic inspection routine to check for visible coating spalling or exposed titanium substrate on the anode surface. Replacement should be carried out promptly when extensive coating spalling is observed.
Q: Are replacement anodes compatible with different brands of salt chlorinators?
A: Yes. We provide custom anode assemblies based on the cell dimensions and connection requirements of your existing salt chlorinator. Simply provide the cell model, anode dimensions, and connection method, and we can fabricate fully compatible replacement anodes for seamless substitution.
