Select the appropriate cell by electrolyte source, chlorine duty, flow conditions and cell geometry.
Titanium Electrolytic Cells & Electrochlorination Cell Assemblies
Need brine preparation, DC power, controls, gas management and dosing as one supply package? Review the Sodium Hypochlorite Generator systems. For an OEM reactor or replacement part, continue with the cell configurations below.
HELE supplies electrolytic-cell components and complete cell assemblies for equipment manufacturers, system integrators, marine systems and replacement projects. Choose the supply level first—electrode assembly, complete cell or full system—then confirm whether prepared brine or natural seawater will be treated.
MMO Titanium Electrode Assembly
Electrode-level component
Titanium Electrolytic Cell

Complete Electrochlorination System
System-level equipment
Product Boundary: CTE, PPE and MESH are electrolytic-cell geometries. Sodium Hypochlorite Generators and Seawater Electrochlorination Systems are system-level products and should be evaluated separately.
Brine Electrolysis or Seawater Electrochlorination?
The electrolyte source is the first major selection step. Prepared NaCl brine and natural seawater differ in chemistry, hydraulic conditions, applications and maintenance requirements, so HELE treats them as separate electrochlorination duties.
Prepared NaCl Brine
For on-site active-chlorine and sodium hypochlorite generation using controlled NaCl solution.
Primary Cell Configuration
PPE — Pipe-Plate Electrolytic Cell
Typical Applications
- Municipal Water Treatment
- Industrial Disinfection
- Cooling Water
- Sodium Hypochlorite Generation
Selection Inputs
NaCl concentration, Required chlorine output, Flow, Current, Voltage, Operating hours.
Natural Seawater
For direct seawater electrolysis in marine, offshore, power-generation and industrial seawater systems.
Available Cell Configurations

- Power-Plant Seawater Systems
Selection Inputs
Seawater quality, Salinity, Flow, Chlorine output, Pressure drop, Current density, Installation space.
CTE, PPE & MESH Electrochlorination Cells
Different cell geometries are available because flow distribution, electrode area, pressure drop, current distribution, maintenance access and installation footprint vary from project to project. The appropriate geometry depends on the required output and the agreed hydraulic, electrical and maintenance conditions.
CTE — Concentric Tubular Electrolytic Cell
Tubular electrochlorination-cell configuration primarily used for natural-seawater applications where compact flow-through geometry and robust integration are required.
Primary Media
Natural Seawater

Flow Rate · Chlorine Output · Current Duty · Pressure Drop · Installation Space
PPE — Pipe-Plate Electrolytic Cell
Pipe-plate electrolysis-cell configuration used as HELE’s primary structure for prepared-brine electrolysis and also available for selected seawater duties.

Chlorine Output · Electrode Area · Current Density · Flow · Maintenance
MESH — Plate-Mesh Electrolytic Cell
Plate-mesh configuration for seawater electrochlorination projects where active electrode area, hydraulic distribution and maintenance access are important design considerations.

Additional Electrolytic Cell Supply Options
In addition to the three primary cell geometries, HELE supports generator-core cells, replacement cells and drawing-based OEM assemblies for existing or newly developed electrochlorination equipment.
Sodium Hypochlorite Generator Cell
Core electrolyzer module for integration into on-site sodium hypochlorite generation equipment.
Pool Salt Chlorinator Replacement Cell
Compact OEM or replacement cell for salt chlorination equipment.
Custom OEM & Replacement Electrolytic Cell
Drawing-based cell assembly for system integrators, replacement projects and non-standard electrochlorination equipment.
How Electrochlorination Cells Generate Active Chlorine
Prepared brine or natural seawater contains chloride ions that can be electrochemically converted into active chlorine species. Cell output depends on feed chemistry, chloride concentration, flow, temperature, electrode area and electrical operating conditions.
Chloride-Containing Feed Enters
DC Current Is Applied
Active Chlorine Is Generated
Treated Stream Leaves the Cell
Safety Note: Hydrogen is generated at the cathode and must be safely separated, ventilated or otherwise managed by the complete system design.
Inside a Titanium Electrolytic Cell
Cell performance depends on more than the MMO coating. Electrode arrangement, hydraulic flow, electrode gap, housing, sealing, electrical contact and gas management all affect output stability, voltage, pressure drop and maintenance requirements.
MMO-Coated Titanium Anode
The active electrocatalytic surface responsible for chlorine evolution. Coating type and loading dictate performance.
Titanium Cathode
Completes the electrical circuit and facilitates hydrogen evolution. Structural integrity is essential.
Electrode Gap & Flow Path
Optimized spacing balances voltage, heat, scaling tendency and hydraulic distribution.
Housing & Sealing
Prevents leakage and ensures structural integrity under system pressure and operating temperatures.
Electrical Connections
Stable terminals and busbars support uniform current distribution and prevent dangerous overheating.

How to Select the Right Electrochlorination Cell
Start with electrolyte and chlorine duty, then evaluate hydraulic, electrical, mechanical and maintenance requirements. This sequence narrows the cell geometry and identifies the information needed for a reliable quotation.
Electrolyte
Prepared Brine → PPE primary
Natural Seawater → CTE / PPE / MESH
Required Chlorine Output
Defines the total active area and overall cell capacity.
Flow & Pressure

Electrical Duty
Operating current, voltage limits and current density targets.
Cell Geometry
CTE, PPE or MESH selection based on flow path and environment.

Electrochlorination Cell Applications
Titanium electrolytic cells serve as the electrochemical core of brine- and seawater-based chlorine-generation equipment across municipal, industrial, marine and OEM applications.
Electrolytic Cell vs Complete Electrochlorination System
The electrolytic cell is the electrochemical reactor. A complete system adds the supporting equipment required to prepare the feed, supply DC power, control the process, manage hydrogen and deliver the generated product.

Define the Cell Duty and Integration Boundary Before Quotation
A titanium electrolyzer or cell must be matched to the reaction, feed, product duty, electrical envelope, hydraulics, electrode geometry and balance-of-system interfaces—not selected from dimensions alone.
- State whether the feed is brine, seawater or another defined electrolyte.
- Define target product, concentration, output and rated operating conditions.
- Provide the current, voltage, current-density and duty-cycle basis.
- Specify cell geometry, electrode configuration, connections and hydraulic interfaces.
- Separate cell supply from power, degassing, separation, controls and commissioning.
Do not release a purchase order with only:
- A cell component and a complete electrolysis system treated as the same scope
- Output stated without feed, concentration or rated conditions
- A generic MMO coating selected without the required anodic reaction
- Hydraulics, gas release or product separation omitted from the interface review
- Cleaning and service access left undefined
