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.
