The anode utilises an innovative ceramic/titanium composite combined with an integral gas venting system. The system includes Ebofix grout, which is a high density, acid buffering grout used for long-term performance. Ebonex anodes are available in a range of sizes, which provide excellent design flexibility. Ebonex discrete anodes are able to provide sufficient performance to satisfy the 100mV potential shift requirement for Cathodic Protection as specified under National Association of Corrosion Engineers (NACE) RP0290 & the European Standard EN12696 - Cathodic Protection of Steel in Concrete. Typical Applications „ Bridges „ Steel framed buildings „ Car parks „ Reinforced concrete in marine conditions Advantages „ Gas venting - no build-up of anodic gases and therefore can be installed under strengthening systems, membranes and coatings „ Discrete installation - no added dead weight loading or increase to physical dimensions of structure „ Long lasting - longest life expectancy of any discrete CP anode - in excess of 40 years, depending upon design „ Highest level of protection - satisfies the 100mV criteria for effective cathodic protection „ Proven technology - field verified performance „ Cost competitive compared with other types of CP installations „ Deep installation - addresses multi-levels of steel in difficult access areas „ High operating current - suitable for use in areas of high steel density „ Versatile - can be used in new construction as a preventative measure „ Flexible - available in a wide number of sizes to provide maximum design flexibility How Does it Work? Ebonex works by distributing sufficient electrical current to overcome on-going corrosion in the structure. The Ebonex anodes are connected to an external DC power supply, which provides the electrical current that mitigates corrosion activity. According to industrial standards, an ICCP system is considered effective when the steel is sufficiently polarised to result in a 100mV depolarisation once the system has been turned off. Description Ebonex is a discrete Cathodic Protection anode system providing long-term durability to both new and existing structures under highly aggressive conditions. In line with other cathodic protection systems, Ebonex discrete anode systems must be designed by corrosion specialists and installed by approved contractors. Level of Protection Description Ebonex Cathodic Prevention Preventing new corrosion activity from initiating 9 Corrosion Control Significantly reduce ongoing corrosion activity 9 Cathodic Protection Highest level of protection intended to stop ongoing corrosion 9 Standards Compliance Ebonex discrete anodes satisfy the 100 mV potential shift requirement for effective cathodic protection as specified under NACE (National Association of Corrosion Engineers) Standard RP 0290-90. The design of Ebonex discrete anodes follows comprehensive criteria established for the patented ‘Ebonex’ (TM) system, described in patent no. PTC/GB99/00359, developed by Atraverda Ltd. April 2011
