CHLOROPAC® - MGPS
Chloropac® systems produce, insitu, a dilute, safe solution of sodium hypochlorite for direct injection into the water circuit for marine growth prevention.
Our advanced electrolyzer technology, available in a choice of basic cell designs — coupled with our long standing expertise in anode and system development — has freed thousands of customers worldwide from the cost of purchasing and the danger of handling harsh chemicals associated with other technologies.
Chloropac utilises CTE technology to provide the most efficient chlorine generation. The newest cell provides an increased capacity per cell for production, thus enabling the chloropac system to be smaller and lighter than previous models – up to 76%. This allows systems to pass through standard hatchways, corridors and into existing footprints with ease and and save on real estate. The patented technology is self cleaning so does not require costly acid washing – leaving you to run you platform, vessel or plant, not worry about biofouling issues.

What is Electrochlorination?
The Evoqua CTE cell is the heart of the Chloropac® unit and provides the technology behind the electrochlorination system. Invented and refined by Electrocatalytic engineers, C.T.E. technology is proven to be operationally reliable.
The C.T.E. electrolytic cell assembly consists of two concentric titanium tubes between which salt water (seawater) flows. By passing electric current through the salt water, Chloropac® converts the sodium chloride into sodium hypo-chlorite, the active ingredient required for anti-fouling.
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 overcomes all of the deficiencies of the previous plate or mesh designs. Electrolyte flow is forced horizontally in the annular space between the concentric cylinders. The flow of electrolyte from the inlet to the outlet connections is uniformly distributed between the concentric anode and cathode surfaces. There are no corners. Thus, there are no low flow/velocity areas where calcareous deposits of calcium and magnesium can precipitate on the electrodes and/or accumulate flow/velocity areas where calcareous deposits of calcium and magnesium can precipitate on the electrodes and/or accumulate.

TYPICAL CHLOROPAC® SYSTEM SHIPBOARD INSTALLATION
The Chloropac® sodium hypochlorite generating system is designed to prevent marine growth in the sea water piping, heat exchangers, sea chests and coolers. Thousands of systems have been installed and is the preferred method of ship owners and operators. Low level continuous hypo-chlorination has been shown to be more effective than other types of marine growth prevention systems.
Chloropac MGPS have been proven within the marine market for over 40 years, and can boast thousands of installations worldwide.
THE PROCESS
A small amount of sea water, 5,7m3/hr (25 GPM) is taken from a sea water line which remains constantly under pressure. The water passes – at high velocity – through the electrolytic cells where part of the salt is converted to sodium hypochlorite. This is then returned to the sea chest and mixes with the incoming sea water. The cooling water will now contain a trace residual sufficient to prevent the attachment and growth of marine organisms, thus keeping all circuits – from intake to discharge – free from fouling. Sea water circulating pumps can be interconnected with the Chloropac system to ensure the output of sodium hypochlorite generated is automatically adjusted to suit the flow rates on board.
COMPARISON TO OTHER METHODS OF MARINE GROWTH PREVENTION
| CHLOROPAC® SYSTEM
|
ALTERNATIVE
|
|
| 1 | With a low continuous dose of 0.5 ppm or less the Chloropac electrochlorination system is able to control Micro as well as Macro fouling organisms. 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. Experience has shown that a dose rate of ~20 ppb is required to control Macro fouling. Additionally, continuous dissolution of copper and aluminium is not effective against micro fouling.
|
| 2. | The Chloropac system utilises platinum on titanium electrolytic cells (anodes) to produce the sodium hypochlorite from sea water. Chloropac cells are warranted for five years. Although in most common conditions normal 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. Thus ongoing the consumable and maintenance costs for the operator are lower with a Chloropac system. |
| 3. | Chloropac system controllers can be adjusted manually or automatically to control the amount of hypochlorite being produced depending on the demand. The overboard discharge can be controlled to zero or near zero residual. |
Copper anodes are dissolved continuously and thus copper is discharged overboard, adding heavy metal pollutants to the ocean.
|
| 4. | 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. All produced Sodium Hypochlorite is also injected 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.
