Understanding Electrochlorination
The Evoqua CTE cell forms the core of the Chloropac® unit, utilizing C.T.E. technology for reliable electrochlorination. Developed by Electrocatalytic engineers, this technology efficiently converts sodium chloride into sodium hypochlorite, the active ingredient for anti-fouling. The concentric electrode design ensures uniform electrolyte flow, preventing calcareous deposits and optimizing system performance.
Enhanced Electrolytic Cell Assembly
The C.T.E. electrolytic cell assembly comprises two concentric titanium tubes through which saltwater (seawater) flows. By applying an electric current to the saltwater, Chloropac® converts sodium chloride into sodium hypochlorite, the active ingredient needed for anti-fouling.Advantages of Concentric Electrode Design
The development of the concentric electrode design resulted in a flow cell constructed of concentric cylindrical anode and cathode assemblies, one inside the other. This C.T.E. design effectively addresses deficiencies in previous plate or mesh designs. Electrolyte flow is horizontally forced in the annular space between the concentric cylinders. The flow of electrolyte is uniformly distributed from the inlet to the outlet connections, covering the concentric anode and cathode surfaces evenly. The absence of corners eliminates low flow/velocity areas where calcareous deposits of calcium and magnesium could precipitate on the electrodes or accumulate.

Typical Chloropac® System Shipboard Installation
The MGPS Mk2M Chloropac® sodium hypochlorite generating system prevents marine growth in seawater piping, heat exchangers, sea chests, and coolers. Ship owners and operators prefer the MGPS Mk2M system, with thousands of installations worldwide. Continuous low-level hypochlorination proves more effective than other marine growth prevention methods. Chloropac MGPS has earned trust in the marine market for over 40 years.
The MGPS Mk2M Process
A small amount of seawater, 5.7m³/hr (25 GPM), constantly pressurized, passes at high velocity through MGPS Mk2M electrolytic cells, converting part of the salt to sodium hypochlorite. This solution returns to the sea chest, mixing with incoming seawater. The cooling water now contains a trace residual sufficient to prevent marine organism growth, keeping all circuits—from intake to discharge—free from fouling. The system can interconnect with seawater circulating pumps to automatically adjust sodium hypochlorite output to suit on-board flow rates.
Comparison MGPS Mk2M to Other Methods
Effective Dosage |
||
|
The Chloropac electrochlorination system effectively controls both micro and macro fouling organisms by low continuous dose of 0.5 ppm or less. Additionally, it ensures efficient marine growth prevention
|
In contrast, copper ion-type systems claim a dose rate of 1 ppb suffices for all marine growth. However, a dose rate of ~20 ppb is actually needed to control macro fouling. Additionally, continuous dissolution of copper and aluminum does not effectively combat micro fouling. | |
Cell Longevity and Maintenance Costs |
||
| The Chloropac system uses platinum-on-titanium electrolytic cells (anodes) to produce sodium hypochlorite from seawater. These cells are warranted for five years, but typically last around seven years. | Conversely, copper-based systems use “sacrificial anodes” that dissolve quickly, requiring replacement every 12-24 months at a high cost. Therefore, ongoing consumable and maintenance costs are lower with the Chloropac system. | |
Control and Environmental Impact |
||
| Chloropac system controllers can be adjusted manually or automatically to regulate hypochlorite production based on demand, allowing for zero or near-zero residual overboard discharge. | On the other hand, copper anodes dissolve continuously, discharging copper overboard and adding heavy metal pollutants to the ocean. | |
Chemical Handling and Safety |
||
| The Chloropac system produces sodium hypochlorite using only ambient seawater, eliminating the need to store biocides or precursor chemicals on board. All produced sodium hypochlorite is directly injected into the sea chests, simplifying purchasing, storage, handling, and chemical logistics. | In contrast, chemical injection systems require the storage and handling of highly corrosive and toxic chemicals, creating additional storage and safety hazards on board. | |
Conclusion
In conclusion, the Chloropac system not only provides superior control but also offers lower maintenance costs and reduced environmental impact. Furthermore, it simplifies chemical handling compared to alternative methods of marine growth prevention. If you have any further questions about the Chloropac system or require spares, do not hesitate to contact us.

TYPICAL CHLOROPAC® SYSTEM SHIPBOARD INSTALLATION
The Chloropac® MLF system effectively prevents marine growth in seawater piping, heat exchangers, sea chests, and coolers. Ship owners and operators, therefore, prefer this method, as evidenced by the thousands of systems already installed. Moreover, continuous low-level hypochlorination has proven to be more effective compared to other marine growth prevention systems. In fact, Chloropac® MGPS has demonstrated its effectiveness in the marine market for over 40 years, with thousands of installations worldwide.
THE PROCESS
A small amount of seawater, specifically 2m³/hr (or 9 GPM), flows from a pressurized seawater line. This water then passes through the electrolytic cells at high velocity, where part of the salt is converted into sodium hypochlorite. Subsequently, the sodium hypochlorite returns to the sea chest and mixes with the incoming seawater. As a result, the cooling water will contain a trace residual of the chemical, which is sufficient to prevent the attachment and growth of marine organisms. Consequently, this process ensures that all circuits—from intake to discharge—remain free from fouling. Additionally, seawater circulating pumps can be interconnected with the Chloropac system, allowing for the automatic adjustment of sodium hypochlorite output to match the flow rates on board.

A COMPARISON WITH OTHER MARINE GROWTH PREVENTION METHODS
CHLOROPAC® MLF SYSTEM |
ALTERNATIVE |
||
1. |
Effectiveness |
||
|
With a low continuous dose of 0.5 ppm or less, the Chloropac electrochlorination system effectively controls both micro and macro fouling organisms. Consequently, it provides comprehensive protection against a wide range of marine growth.
Micro = Slime, algae and weed.
Macro = Barnacles,mussels, clams, hydroids, etc.
|
In comparison, manufacturers of copper ion-type systems suggest a dose rate of 1 ppb will be sufficient to control all marine growth. Controlling Macro fouling typically requires a dose rate of minimum 20 ppb. Additionally, continuous dissolution of copper and aluminium is not effective against micro fouling.
|
||
2. |
Warranty |
||
| The Chloropac system utilises platinum on titanium electrolytic cells (anodes) to produce the sodium hypochlorite from sea water. Chloropac cells come with a five-year warranty. Although, under most common conditions, the typical cell life is approximately seven years.
|
Copper based systems use “sacrificial anodes” that dissolve rapidly and need to be replaced every 12-24 months at a very high cost. Therefore, ongoing consumable and maintenance costs for the operator are reduced with a Chloropac® system. Consequently, it offers a more cost-effective solution compared to alternatives. |
||
3. |
Impact on the Environment |
||
| Chloropac system controllers can be adjusted manually or automatically to control the amount of hypochlorite being produced depending on the demand. You can control the overboard discharge to achieve zero or near-zero residual levels. |
Continuous copper anode dissolution releases copper into the ocean, adding heavy metal pollutants.
|
||
4. |
Storage and Safety |
||
| As the Sodium Hypochlorite is produced by using only the ambient sea water, no biocides or pre cursor chemicals are required to be stored on board the vessel. The system injects all produced Sodium Hypochlorite directly into the sea chests. This simplifies purchasing storage, handling and chemical logistics on board. |
Chemical injection systems require the purchase storage and handling of highly corrosive and toxic chemicals. This creates an additional potential storage and safety hazard on board.
