Lida Anode "Net" by De Nora Tech

MMO Mesh Anode for Quick Installation in Structural Concrete Structures

  • Description

    • Even current distribution the highly expanded mesh pattern provides uniform cathodic protection current to the rebars.

    • Pre-fabricated the LlDA® NET Anode arrives at the job site ready to be rolled out, fastened down and connected.

    • Quick all weather installation no need to wait for curing, mixing of chemicals, cutting of slots or spraying of paints; there are no electrical splices in the concrete.

    • Activation coating mixed metal oxide coating; the LlDA® NET produces mainly oxygen.

    • Quality control LlDA® NET Anode is manufactured under strict quality control procedures, quality control certificates are provided on request .
