To achieve the highest protection from an impressed current system we need an anode with a very low consumption rate and a high current capacity. SYNCOR mixed metal oxide (MMO) anodes can reach these requirements.
SYNCOR Mixed Metal Oxide are comprised of a titanium substrate coated by a mixed metal oxide of Iridium (IrO2) and Tantalum (Ta2O5).
The MMO coating has the following advantageous properties:
- Excellent conductivity
- Resistance to acidic environments
- Chemical stability
- Relatively low consumption rates
- Suitable for use in both chlorine and oxygen evolving electrolytes
- Life expectancy of over 50 years
- Simple and easy to install.
MMO Ribbon
MMO Anodes consist of a titanium substrate coated with a precious mixed metal oxides (IrO2/Ta2O5). The mixed metal oxide is to activate the titanium and enables it to function as an anode. The life of the MMO anode coating is dependent on the surrounding electrolyte, such as fresh water, brackish water, seawater, coke, or sand. Based on accelerated life testing conducted, our MMO coating has proven to be superior to other MMO coatings.
