A sodium hypochlorite titanium anode is bought for one electrochlorination duty, not by choosing a generic coated mesh. Feedwater composition, chloride concentration, target chlorine output, current loading, cell hydraulics and electrical connection govern the electrode group. Five company-owned pages met the source rule and exposed different boundaries: loose anodes, assembled cells and broader equipment systems.
How the five company sources were selected
We froze the query sodium hypochlorite titanium anode supplier electrochlorination MMO on 1 September 2026. Eligible sources were company-owned anode or electrochlorination pages that expressly connected a titanium/MMO electrode to hypochlorite production and exposed a coating, geometry, current, cell or process field. Beiyu, geographies excluded by site policy, marketplaces, directories, third-party rankings and pages limited to finished disinfectant chemicals were removed. The order below records discovery after exclusions; it is not a supplier score.
A public page can identify a likely supply route. It cannot prove allocated stock, a current program approval, final schedule, lot compliance or suitability of material/equipment not yet produced or assigned. Those points remain dated quotation fields.
Company pages that met the rule
| Company source | Page role | Visible fields | RFQ check |
|---|---|---|---|
| Insoluble Anode Technology | Titanium-anode manufacturer/application page | Netherlands manufacturer; MMO compositions, titanium machining/welding and hypochlorite-production route | Return the actual oxide system, substrate, geometry, active area, connection and duty |
| Giant Anode | MMO/anode-cell product family | Ru-Ir and Ir-Ta families plus sodium-hypochlorite electrolytic-cell and assembly routes | Separate loose electrode, anode group and complete cell in the quotation |
| TJNE Global | Industrial electrochemical solutions page | Sodium-hypochlorite/electrochlorination cells, titanium anodes and equipment modules | Define the deliverable and one responsibility/interface matrix |
| Ultranode | Electrochlorination MMO-anode page | Titanium/MMO electrode for seawater or diluted-brine hypochlorite production and cell-capacity context | Give water chemistry, salinity, current, cell layout and quotation-specific life basis |
| Chengyun Titanium | Application-specific electrode page | Plate/tube forms, custom drawing route, current-density band and test references | Reconfirm units, edition, coating load, electrical interface and acceptance evidence |
The five pages do not offer the same object. A coated plate, an assembled anode group, an electrolytic cell and a complete sodium-hypochlorite package place power supply, cathode, seals, flow distribution, gas management and controls on different parties. A commercial comparison is invalid until that supply boundary is held constant.
Freeze water chemistry and cell boundary first
| Decision | Choices visible in the source set | Required written return |
|---|---|---|
| Feed and output | Seawater or prepared brine; chloride, hardness, temperature and target available chlorine | Normal/range/upset composition, feed rate, product concentration and mass output |
| Electrode system | Ru-Ir or other MMO family, titanium substrate, cathode pairing and polarity | Named coating route, substrate grade/form, coating load or accepted proxy and pairing |
| Electrical duty | Current, voltage, current density, active area and rectifier ripple | Operating window, allowable excursions, terminals and busbar/contact design |
| Cell hydraulics | Electrode gap, flow path, pressure drop, scaling, gas release and cleaning | Assembly drawing, wetted materials, maintenance method and replacement access |
| Acceptance/life | Coating verification, polarity/continuity, performance test and life basis | Methods, sample/lot, criteria, test fluid and exclusions tied to the quotation |
Do not compare anode life statements without the same chloride concentration, current density, temperature, cleaning practice and definition of end of life. Calcium and magnesium scaling can change local current distribution even when the catalytic coating is unchanged. The RFQ should identify whether acid cleaning is allowed, which party owns the cleaning procedure, and whether reversed polarity or dry running is credible. It should also define the gasket, housing, cathode, busbar, cable and rectifier boundaries. If only replacement electrodes are ordered, require a measured interface drawing and identify the existing cell manufacturer, serial/configuration and installed spacing instead of assuming nominal interchangeability.
A page conflict is a verification prompt, not a finding that a company cannot supply the item. Preserve the observed difference, request a clean technical return and make the purchase order control final identity, geometry, responsibility and acceptance.
Send one controlled RFQ
| RFQ line | Buyer input | Supplier return |
|---|---|---|
| Process basis | Feed analysis, salinity/chloride, temperature, flow and required product output | Design point/range, excluded contaminants and expected efficiency basis |
| Supply boundary | Loose anode, anode/cathode pack, cell, skid or complete system | Included components, interfaces, utilities and design responsibility |
| Electrode | Coating family, substrate, active area, geometry, spacing and connection | Drawing, process route, coating record and electrical contact details |
| Operation | Current/voltage range, duty cycle, cleaning, pressure and control philosophy | Operating limits, alarms/interlocks and maintenance instructions |
| Inspection | Dimensional, coating, continuity, pressure/leak and performance checks | ITP, methods, criteria, reports and witness/hold points |
| Commercial | Quantity, spares, documents, packing, required date and destination | Current schedule, validity, exclusions, preservation and warranty basis |
Remove any source that cannot return the exact material, deliverable, finished geometry and acceptance evidence. Compare price, schedule and terms only after technical lines, responsibility boundary and document scope are aligned.
Where Beiyu fits
Beiyu is outside the five-company set. Its sodium-hypochlorite anode route asks for feedwater/brine analysis, target chlorine output and concentration, flow, operating current/voltage, electrode/cell boundary, coating family, titanium substrate, active area, geometry, spacing, electrical connection, cleaning, inspection, documentation, quantity and destination before confirming an offer.
The fields in this section describe only Beiyu’s published enquiry route. They do not score the companies above and do not transfer to another company’s catalogue.

Specification detail with sources
Beiyu Titanium publishes this list and is not part of the comparison above. For readers who want the publisher’s own figures on the same basis they would ask of any supplier on this page, the material is specified to ASTM B265 and ASTM B338, and each order carries an EN 10204 type 3.1 certificate with heat and pour numbers by order scope.
In the coating systems Beiyu supplies, the ruthenium system runs chlorine evolution below 2000 A/m2 with a 5 to 20 micrometre coating carrying 5 to 20 g/m2 of precious metal, and is used in brine and seawater duty with hydrochloric content below 20 percent.
These are Beiyu published supply figures, not limits taken from the standard; limit values belong to the standards named above and are confirmed against the exact edition on the purchase order. Certification is stated as a production capability, and no stock position, delivery time or price is implied by any figure on this page.
