Corrosion Protection

As inhibitor we use aluminium cathodically dissolved as aluminate. The Catolysis module is mounted in a side stream of the cooling circuit. The aluminate will form a protective layer on all surfaces in contact with water.

 

The presence of aluminium as aluminate in the circulating coo-ling water will minimize surface corrosion in the system. Aluminate works as flocculation and will in this way work together with the filter.

 

This is done by the aluminate collecting the particles into flocks that can easily be removed in the side stream filter. Guldager’s corrosion protection is free of chemicals.

Guldager’s new control unit for corrosion protection provides several advantages regarding controlling and monitoring of the plant for corrosion protection.

 

Katolysis is a process developed on basis of the well-known principles for electrolytic corrosion protection. With electrolysis, the anode is dissolved, while with Katolysis, it is the cathode, which is dissolved. The whole process takes place inside the CatoCool unit.

 

Guldager CatoCool protects the pipe system of the installation against rust. The CatoCool plant consists of a treatment part, an electronics unit, and a pump.

 

The treatment part is an enamelled or plastic coated tank with two electrodes. An aluminium cathode and an anode of titanium thread coated with noble metals. The anode is winded round the cathode in a spiral.

 

The electronics unit supplies current (low tension, D.C.) to the anode. As a result, the aluminium cathode is slowly dissolved as aluminate ions, which are lead into the pipe system. Along with the metal oxides from the surface of the pipes, the aluminate ions form a protective layer in the entire pipe system. The protection layer prevents rust and corrosion in the pipes.

 

The pump ensures a constant flow through the treatment unit and into the pipe system.
