Aluminium anode for cathodic protection of seawater cooling system is the key to anticorrosion, protecting other metals by sacrifice.AT series aluminium anodes are commonly used for corrosion resistance, good electrochemical performance and long life. Used in cooling towers, ships, etc. to extend system life and improve efficiency. Selection and installation need to consider the system requirements, the principle of corrosion protection is based on potential difference protection. 

This optimized aluminum-zinc-indium-cadmium alloy formulation is designed to deliver higher current efficiency, more uniform consumption rates, and more stable operating potential, making it particularly suitable for demanding seawater environments.

Aluminium Anodes in Seawater Cooling System

Aluminium anodes in seawater cooling system are mainly used in many fields such as cooling towers, ships, seawater desalination units and so on.

Through the sacrifice of aluminium anode, the service life of seawater cooling system can be effectively extended, the operation and maintenance cost of the system can be reduced, and the stable operation of the system can be ensured.

 Aluminium anode can also improve the efficiency of the cooling system, because it can reduce the wear and tear of pipes and valves due to seawater corrosion, thus reducing the flow loss and improving the operational efficiency of the system.

Why Choose AT-1 Aluminum Alloy Anode?

Optimized Alloy Composition:

The addition of zinc, indium, and cadmium effectively inhibits the self-corrosion of aluminum in electrolytes, enhancing anode utilization and protection efficiency.
