Protect Assets
Control corrosion on pipelines, tanks, buried infrastructure, reinforced concrete, marine structures or other defined assets, or manage biological fouling within seawater circuits.
Electrochemical Solution Pathways
Industrial Electrochemical Solutions Built Around Your Process
Start with the target reaction, electrolyte, electrical duty and operating environment. HELE routes industrial requirements to the relevant titanium-anode, electrode or electrochemical solution path before product selection.

Buyer Selection Guide
Start with the Process, Then Define the Electrode
The right electrode solution depends on the target reaction, electrolyte composition, current or current density, temperature, operating cycle, geometry and equipment boundary. Define these conditions first so the coating family, titanium substrate, electrode configuration and documentation requirements can be reviewed against the actual process.
Process Objectives
What Must the Electrochemical System Achieve?
Start with the required process outcome, then use the operating conditions, equipment boundary and acceptance criteria to identify the relevant technical path before comparing electrode products or system components.
Generate Chemicals
Produce chlorine, sodium hypochlorite or another defined electrochemical output from brine, seawater or a specified process electrolyte.
Recover or Deposit Metals
Recover metals from a defined electrolyte or deposit a controlled metallic layer or electronic material under specified cell conditions.
Treat Water or Support Separation
Oxidize contaminants, disinfect water or define electrode requirements within a water-treatment, desalination or ion-separation system.
Core Solution Paths
Navigate by Process, Not by Product List
Each path links the process goal to the first technical inputs required for a meaningful review. Final electrode or component selection remains project-specific.

Technical Intake
Inputs That Change the Solution Path
A useful first review does not require every answer, but unknown items should be identified rather than guessed.
Target Process
State what must be protected, generated, recovered, deposited, oxidized, disinfected or separated.
Electrolyte & Chemistry
Provide composition, concentration, contaminants, pH, conductivity and relevant analysis.
Electrical Duty
Define current, current density, voltage, waveform, polarity and operating cycle.
Operating Environment
Include temperature, flow, pressure, gas evolution, scaling, fouling and cleaning conditions.
Geometry & Connection
Share active area, dimensions, spacing, mounting, terminals, cable and cell or equipment drawings.
Acceptance Evidence
Define target output, service-life basis, inspection, reports, certificates and customer approval requirements.
Electrode Family Boundary
Electrode Technologies Are Not Interchangeable
Similar shapes do not mean equivalent electrochemistry. The target reaction, electrolyte and evidence requirements determine which technology can be evaluated.
Chlorine-Evolution MMO Paths
Often considered for defined chloride-containing electrochemical duties such as electrochlorination or chlor-alkali. Electrolyte, current density, temperature and geometry must be reviewed.
Oxygen-Evolution MMO Paths
Ir-based or Ir-Ta-related systems may be relevant to defined oxygen-evolution or oxidation duties. They are not a universal substitute for other coatings.
Platinized Titanium Paths
May be relevant to selected electroplating, electrolysis, testing and specialty processes when platinum thickness, surface area and chemistry are specified.
BDD & PbO₂ Paths
Can be considered for selected advanced-oxidation or electrochemical-treatment duties. Chemistry, substrate, validation and evidence requirements differ from MMO systems.
Scope & Evidence
A Solution Name Is Not a Finished Specification
The same process can require different chemistry, geometry, connections, tests and supply boundaries. HELE should not be presented as supplying a complete system, fixed service life or universal certification unless the quotation and applicable evidence explicitly confirm it.
- Separate electrode, cell, component and complete-system scope
- Link coating or material evidence to the exact product and order
- Record customer, integrator and HELE design responsibilities
- Define performance measures, exclusions and acceptance criteria before quotation
From Process Need to Quotation Scope
- 1. Define the process objective. State the required reaction or protection result.
- 2. Capture the operating window. Record chemistry, electricity, geometry and environment.
- 3. Select a review path. Route to the relevant solution and electrode family.
- 4. Confirm the supply boundary. Separate component, cell and system responsibilities.
- 5. Agree evidence. Define tests, reports, approval and quotation assumptions.

Solution FAQ
Questions Before Electrode Selection
Can HELE select an electrode from the application name alone?+
No. The same application can use different electrode chemistries and geometries. A review needs the target reaction, electrolyte, pH, temperature, current density, dimensions, operating mode and acceptance basis.
Are MMO, platinized titanium, BDD and PbO₂ electrodes interchangeable?+
No. They have different electrochemical functions, operating windows, substrate or coating structures, validation needs and commercial implications. Selection must be process-specific.
What if the project is a replacement for an existing electrode?+
Provide the drawing, markings, substrate and coating if known, electrical connection, process chemistry, operating data, service history and observed failure mode. A visual match alone is insufficient.
Does a solution card mean HELE supplies the complete process system?+
Not automatically. Some inquiries may cover an electrode or component; others may involve a cell or selected system scope. The quotation must state inclusions, exclusions, design responsibility and documentation.
Can service life or performance be guaranteed before operating conditions are reviewed?+
No. Life and performance depend on chemistry, electrical duty, geometry, preparation, coating, maintenance and the agreed operating envelope. Any commitment must be model- and order-specific.
What documents can be discussed for an electrochemical project?+
Depending on the confirmed product and order scope, the discussion may include material records, dimensions, coating or composition evidence, inspection reports, drawings, packing documents or third-party review. Availability must be confirmed before order placement.
