The ELTECH LIDA® ONE anodes are the newest in the family of mixed metal oxide anode products specifically tailored to the cathodic protection of buried structures. Designed for installations where a single anode on a string is preferred for groundbeds with widely varying soil resistivities, the mixed metal oxide coating is specially formulated for use in a carbonaceous backfill.
LIDA® ONE is a 1″ diameter titanium tube with a precious metal oxide coating. This mixed metal oxide is a crystalline, electrically-conductive coating that activates the titanium and enables it to function as an anode. When applied on titanium, the coating has an extremely low consumption rate, measured in terms of milligrams per year. As a result of this low consumption rate, the tubular dimensions remain nearly constant during the design life of the anode – providing a consistently low resistance anode.
By increasing the length of our tubular anode, yet reducing total current output, ELTECH Systems Corporation has created another reliable mixed metal oxide anode product line with even greater cost savings over competitive anode technologies. As with all of ELTECH’s mixed metal oxide tubular anodes, the combination of a tough and lightweight product, its ease of handling and installation, the superior mechanical connection, and our five year, no hassle warranty, makes LIDA® ONE the ONE anode for unparalleled CP performance.

Regardless of the type of impressed current anode used, proper ground bed design is paramount to optimum, low resistance performance. ELTECH Corporation recommends the use of quality, conductive, carbonaceous backfill, a vent pipe, and centralizers, suitable cable, and good design practices and understanding.
