CHLOROPAC Electrochlorination Systems

Chemical-free, self-cleaning technology used to provide a continuous output of hypochlorite from a feed of sea water

The Chloropac® system processes a sea water side stream from a main sea water flow to continuously produce hypochlorite for reinjection. The Chloropac system produces chlorine, without the need for additional chemicals using a combination of specially coated anode tubes and a direct electrical current. The avoidance of chemicals eliminates the need for storage and handling of liquid hypochlorite, resulting in increased safety and operating cost reduction.

More than 40 years of proven application utilizing in-situ self cleaning Chloropac® cells generating sodium hypochlorite.

  • Generation is on-site so there is no storage, handling or movement of hazardous chemicals
  • IP44 and IP56 (ATEX & IECeX versions) electrical enclosures with easy access and reduced footprint

System Overview

Chloropac® systems produce, in situ, a dilute, safe solution of sodium hypochlorite for direct injection into the water circuit for prevention of growth of common marine species. 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. Evoqua's Chloropac system is a patented design utilising Concentric Tube Electrolysis cells or CTE technology to provide the most efficient chlorine generation with high internal velocities to keep the cell active surfaces clean. Chloropac system cells are available in a wide capacities, thus enabling the Chloropac cells to be packaged in to standard electrolyser or a full packaged system that are both compact and with significant weight savings. This allows systems to pass through standard hatchways, corridors and into existing footprints with ease. The patented technology is self cleaning so does not require costly acid washing – leaving you to run you platform, vessel or plant, and not worry about biofouling issues.
