In chlor-alkali plants, sodium hypochlorite generators, electrochlorination units and electrodialysis stacks, the anode is the workhorse: it discharges the current that drives chlorine or oxygen evolution at the electrolyte interface. Ru-Ir MMO coatings lower the overpotential for chlorine evolution, hold precious-metal loading at the level your current density demands, and convert electrical energy into usable chemical output with minimal loss.
Coating, current density and life are linked in one equation: run the anode below its rated A/m² and the coating lasts for decades; push it without a matching loading and precious metal is consumed in months. That is why Ehisen specifies the coating system — RuO₂/IrO₂ for brine and chloride media, IrO₂/Ta₂O₅ for oxygen-evolving duty, platinum for high-purity recovery — from your electrolyte, temperature and target life, not from a stock list.
Every electrolysis process attacks the anode differently. Match the challenge below with the coating and format Ehisen supplies for it.
Membrane and diaphragm cells run at high current density with saturated brine at 80–90°C. Poor coating control raises cell voltage, increases energy cost and shortens anode life.
On-site generators electrolyse dilute brine or seawater with intermittent duty cycles. Anodes must restart cleanly and resist pH drift and chlorine-side passivation.
Seawater electrochlorination for biofouling control in cooling circuits and ballast systems exposes anodes to suspended solids, variable salinity and chlorate by-products.
Electro-oxidation, electrocoagulation, electrodialysis and electrolytic recovery run in acidic or contaminated media where oxygen evolution, fouling and poisoning dominate.
Different electrolysis processes require different coatings and formats. Use the guide below to match your application with the most suitable Ehisen solution.

An electrolysis plant is a system, not a single product. Every component below works together to convert electricity into chemical product — and Ehisen supplies the coated anode core of it.
The current-discharging element — Ru-Ir, Ir-Ta or platinized titanium coatings on plate, mesh, tube or wire formats, rated to your electrolyte and design life.
Cathodes (mild steel, nickel or activated) and cell frames, gaskets and busbars that complete the circuit and hold the electrode geometry stable.
Ion-exchange membranes or diaphragms separate anolyte and catholyte, control product purity and keep the anolyte chemistry within the anode rating.
Converts AC mains to regulated DC and holds the cell at constant current or constant voltage — the key to stable anode operating conditions.
Feed pumps, filters, heat exchangers and brine saturation keep chloride concentration, temperature and flow uniform across every anode.
Cell voltage, current, pH, temperature and product concentration are logged per cell so coating condition and replacement timing can be predicted.
An electrolysis anode supply follows a proven four-stage sequence. Ehisen supports you in every stage with engineering input and documented hardware.
Electrolyte composition, temperature, cell current and target product are defined, then active area, coating and anode geometry are calculated for the design life.
The coating system (Ru-Ir, Ir-Ta or platinum) and precious-metal loading are fixed, then verified with coating inspection and accelerated life testing.
Anodes are installed, current is ramped to the rated density, and cell voltage, temperature and product quality are checked against the design basis.
Cell voltage and coating condition are tracked so replacement timing is planned — keeping production online instead of failing at the worst moment.
Buyers choose Ehisen because coating consistency, traceability and engineering response decide how long a chemical anode really lasts — not just the catalogue price.
Coating applied on our own production line with a fixed formulation and controlled loading tolerance — samples and bulk runs are made to the same standard.
Every batch carries a LOT number linking substrate material, coating process records, inspection results and shipping documents.
Accelerated life testing in NaCl and H₂SO₄ media at 10,000–20,000 A/m² converts laboratory hours into your operating rating.
Our engineers review electrolyte, cell type and current density, then recommend coating, geometry and quantity — within 24 hours.
Export experience across 40+ countries with complete documentation: MTC, coating reports, inspection records, certificate of conformity.
Production planned against your project schedule, with order status updates from coating to packing list.
A clear, three-step process keeps every chemical anode order on specification and on schedule.
Share your application, electrolyte, cell current and target life via WhatsApp or email — or send a cell drawing and we will extract the parameters.
Within 24 hours you receive a recommendation: anode format, coating system, dimensions, quantity and the supporting calculation basis.
After approval, production runs with batch QC, then ships with the full document pack: MTC, coating report, ALT data and packing list.
