RONGDE electrolytic anti-fouling & anti-corrosion electrode is specialized marine equipment designed for ship seawater pipeline, sea chest and cooling water system, available in pure copper electrode and high-purity aluminum electrode two types. Matched with constant-current control power supply, the paired Cu-Al electrodes complete pipeline anti-biofouling and metal anti-corrosion simultaneously, widely used on cargo ships, fishing vessels, yachts and offshore platforms.
The sea chest copper aluminum electrode serves as a critical component designed specifically for shipboard seawater pipelines and sea chest compartments. Targeted at marine engineers and vessel operators, this device provides an all-in-one solution preventing biofouling and corrosion simultaneously. Its design accommodates integration with existing systems such as the marine mgps system to ensure operational continuity and risk mitigation. Suitable for various vessel types, it is recommended for professional users seeking long-term reliability in harsh maritime environments and sustained seawater immersion conditions.
Employing paired pure copper and high-purity aluminum electrodes, this equipment utilizes electrolysis to inhibit marine organisms and protect metal surfaces. The copper electrode releases ions that disrupt biofilm and barnacle formation, while the aluminum electrode produces hydroxide flocs forming a corrosion-blocking film over steel surfaces. Key technical specs include working barrel dimensions of φ150 × 480 mm and protection radii reaching up to 3 meters for the copper electrode. Its fully sealed waterproof terminal housing combined with shockproof rubber isolation guarantees durability. The device is supported by matched constant-current control power supplies ensuring stable performance in variable seawater conditions.
Widely deployed in ship seawater pipelines, sea chests, and marine cooling water systems, this product from a reputable marine anti-fouling device supplier optimizes maintenance cycles by reducing fouling-related downtime. It is equally applicable in retrofitting existing marine mgps system infrastructures and new vessel installations. The device effectively extends the lifespan of vital seawater intake components on cargo ships, offshore platforms, and fishing vessels. Through reducing biofouling and electrochemical corrosion, it delivers measurable ROI in operational cost savings and enhanced vessel safety compliance.
Working Principle
1. Copper Electrode for Anti-Biofouling
Energized copper electrolyzes seawater to release trace copper ions. Ions circulate along entire seawater piping to restrain adhesion of barnacles, algae, mussels and other marine organisms, preventing pipeline blockage caused by biofouling.
2. Aluminum Electrode for Anti-Corrosion
Aluminum electrolyzes in seawater to produce aluminum hydroxide floc, which evenly adheres on inner wall of steel pipelines & sea chest steel plates to form dense isolation coating, blocking seawater electrochemical corrosion of hull metal structures.
