Titanium Electrolytic Cells & Electrochlorination Cell Assemblies
HELE supplies electrolytic-cell components and complete cell assemblies for equipment manufacturers, system integrators, marine systems and replacement projects. The product scope is organized by both electrolyte type and cell geometry so engineers can select the correct level of equipment before reviewing detailed specifications.
MMO Titanium Electrode Assembly

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.

Natural Seawater
For direct seawater electrolysis in marine, offshore, power-generation and industrial seawater systems.

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. Use this overview to identify the most relevant cell type, then review its dedicated product page for detailed specifications.

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.

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.
