Product Description
RDDJ-300 Electrolysis Of Seawater Anti-fouling Device
Product Introduction:
The Marine Electrolysis of Seawater Anti-fouling Device is an advanced, environmentally friendly system that prevents marine biofouling in seawater pipelines, sea chests, and cooling systems by generating sodium hypochlorite (NaOCl) directly from seawater through electrolysis. This active, chemical-free solution eliminates the need for external biocides or heavy metal release, making it the preferred choice for vessels operating in environmentally sensitive waters.
Unlike traditional copper-based antifouling systems, this device produces only natural, self-decomposing biocides (hypochlorite) that break down into harmless salt and water – leaving no persistent residues in the marine environment.

Key Features:
1.No Heavy Metals
Zero copper, zinc, or other heavy metal discharge – fully compliant with stringent environmental regulations (IMO AFS Convention, EU BPR, US VGP).
2.On-Demand Biocide Generation
Produces sodium hypochlorite continuously from seawater – no chemical storage or handling required.
3.Automatic Operation
Microprocessor-controlled system adjusts chlorine output proportionally to seawater flow rate, temperature, and salinity.
4.Proven Antifouling Effectiveness
Hypochlorite kills marine organisms (barnacle larvae, mussel spores, algae, bacteria) before they attach to pipe walls and equipment.
5.Self-Decomposing
Residual hypochlorite naturally decomposes into chloride and oxygen within minutes to hours – no environmental accumulation.
6.Corrosion Resistant Construction
Titanium or MMO (Mixed Metal Oxide) coated electrodes for long service life in aggressive seawater.
7.Compact & Modular Design
Small footprint suitable for engine room or control room installation.
8.Remote Monitoring
Optional 4-20 mA output and alarm relays for integration with ship automation systems.
