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.


Technical Specifications:

Electrolytic cell life > 5 years
Power supply AC380V~AC400V 50Hz/60Hz 3ph
Seawater pump Q=6m3/h, H=32m
Installation method self-supporting
Coating Musell
Protection grade IP22 (control room) and; lP54 (electrolytic room)
Inlet pipeline DN40, PN0.6MPa, CPVC
Outlet pipeline 2XDN40, PN0.6MPa, CPVC


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.
