Product introduction
Mixed Metal Oxide Anode is suitable for many environments, such as soil, fresh water, saline water and seawater. At present, it is the most promising product to replace high silicon cast iron anode in cathodic protection, with light weight, long service life and high cost performance.
- Product features:
- MMO tubular anode has a large specific surface area, so the current output is large and the anode grounding resistance is small.
- MMO tubular anodes can reduce installation costs by 15-35% compared to other anodes.
- The unique flexibility of MMO tubular anodes facilitates handling, transportation and installation.
