Solution Selection Guide
Start with the Cell and Brine Conditions
A chlor-alkali anode cannot be defined from the process name alone. Cell type, brine composition and impurities, current density, temperature, electrode geometry, connection, coating history and qualification requirements must be reviewed before the coating path or replacement scope is confirmed.
Before Requesting a Quote
Confirm whether the required scope is a coated anode, a complete anode assembly, a drawing-based replacement or a recoating feasibility review. Include the cell type, brine analysis, electrical duty, anode drawing, connection and qualification requirements, and identify any membrane, cell or process responsibilities that remain outside the anode supply scope.
Process Review
Build the Specification in the Right Order
A reliable chlor-alkali anode specification begins with the cell configuration and purified-brine conditions, then defines the electrical duty, operating temperature, electrode geometry, connection details, replacement basis and qualification requirements.
Characterize the Brine
Provide NaCl concentration, purification basis, impurities, pH and operating temperature.
Confirm Electrical Duty
State current, current density, voltage, active area, operating cycle and target basis.
Qualify the Assembly
Share drawings, mesh or plate geometry, connection, tolerances, inspection and approval requirements.
Solution Configurations
Match the Supply Path to the Operating Conditions
Use the confirmed process conditions to compare material, coating, geometry, assembly and documentation requirements. Final configuration remains project-specific.

Brine Chemistry
NaCl concentration, purification, hardness, sulfate, contaminants, pH and temperature.
Electrical Load
Current, current density, voltage, active area, duty cycle and operating hours.
Anode Geometry
Plate or mesh design, dimensions, thickness, spacing, welds, terminals and tolerances.
Replacement Basis
Existing model, drawing, coating history, service data and observed degradation or damage.
Qualification
Inspection, composition evidence, dimensional records, sample approval and documentation.
Supply Scope & Qualification
Define Responsibilities Before Quotation
HELE can review Ru-Ir or other project-approved coated titanium anodes and assemblies for defined chlor-alkali conditions. Process licensing and complete membrane-cell technology are excluded unless explicitly stated in the quotation. Coating, performance, recoating feasibility and service-life commitments require project-specific confirmation.
Anodes & Cell Environments
Chlor-Alkali Anode Configurations
Review representative anode structures, replacement assemblies and chlor-alkali operating contexts. Cell design, brine quality, electrical duty and qualification requirements determine the final anode specification.

Questions Before an RFQ
Is one Ru-Ir coating suitable for every chlor-alkali cell?
No. Brine quality, impurities, current density, temperature, geometry and qualification requirements affect the coating and assembly review.
Can HELE copy an existing replacement anode from photos?
Photos help, but a reliable review also needs drawings, dimensions, connection details, cell conditions, coating information if known and service history.
Can every used anode be recoated?
No. Substrate condition, distortion, remaining dimensions, contamination, prior treatment and economics must be assessed before recoating is accepted.
Are the membrane and complete cell included?
Not automatically. The quotation must define whether the scope is the anode, anode assembly, refurbishment review or another specifically agreed item.
