Geiger® Cathodic Corrosion Protection Systems
An efficient cathodic protection system is vital for the long-term reliable operation of water intake systems.
Our facilities based in Germany are specialized in the engineering and manufacturing of seawater and buckish water intake equipment and boast many decades of experience in the protection of water cleaning machines against corrosion caused by electrochemical reactions.
Benefits and Features of the Impressed Current Solution ICCP
• The project-specific quantity, dimension and position of the impressed
• The evenly distributed, fine-tuned and customized protection current supply
• The constant monitoring of the required protection potential
• The automatic adjustment of the protection current supply to corrosion-
affecting changes in the ambient conditions
• The modular concept that makes it possible to design the system in a flexible
and cost-effective manner
• The compact impressed current anodes, available in several sizes for
optimization of the technical design and for cost effectiveness (compact
• The wire anodes that are specifically installed in the guideways of travelling
band screens to protect its chains
• The system’s longevity: service life time up to 30 years with recommended
maintenance activities and guaranteed spare parts availability thanks to
Geiger® in-house design
• The minimal expenditures for maintenance and regular function checks
The Geiger® impressed current cathodic corrosion protection system (Geiger® ICCP) is a special solution developed for the optimal protection of water intake screening equipment due to its active protection measurable via a PLC panel (compared to the disadvantages of sacrificial anodes -mentioned below). It is based on the well-known functioning and design principles of the protection of carbon and stainless steel against electrochemical corrosion. The Geiger® ICCP system also contributes to reduce corrosion induced by microbes (MIC).
More than one hundred corrosion protection systems that have been designed and manufactured in Karlsruhe are in use around the world. Many of them have been installed in the Mediterranean and Gulf Region, where the screening equipment to be protected is exposed to particularly corrosive sea water at high temperatures and salinity.
Corrosion Protection with Sacrificial Anodes
It is also possible to implement the protective current principle by means of galvanic anodes, which are also referred to as sacrificial anodes. They are electrically connected to the objects to be protected with a conductive bond. Under the effect of the electrolyte, the less noble metal of the sacrificial anodes (usually aluminium or zinc) is dissolved. The thus generated surplus of electrons flows to the object to be protected as protective current.
Sacrificial anodebased corrosion protection systems have one advantage: relatively low material and installation costs. However, there are also some serious disadvantages. For instance, the protective effect is not directly measurable and only a relatively small amount of protective current can be delivered. This, among other things, means that a large number of anodes and a long startup phase are required until the protective cover layers are formed. The short service life time of around 25 years is another disadvantage of sacrificial anode systems, which results in high operating costs and the risk of an undetected loss of protection. Therefore we recommend the more sustainable Geiger® ICCP system instead of sacrificial anodes.
