Impressed Current [ICCP] System

Impressed Current ICCP System

Using an arrangement of anodes-reference cells connected to a control panel, the system produces a more powerful external current to suppress the natural electro-chemical activity causing the dissolution-corrosion of metal.

This eliminates the formation of aggressive corrosion cells on the metal infrastructure and prevents the consequences of dissimilar metals being connected through welding or brought into proximity.

ICCP systems utilize an external DC power source, such as a transformer rectifier, as well as a feedback control system. They can be self-regulating by comparing the measured potential with the desired non-corroding structure potential, the control unit of the ICCP system determines whether the current feed should be increased, decreased or maintained. The objective is to ensure that the potential of the structure as measured by the Reference Electrodes is as close to the desired protection potential as possible.

An ICCP (Impressed Current Cathodic Protection) unit is purpose designed to safeguard an operator’s investment against corrosion with an expected time frame of protection of up to 20 years.
