ELTECH™
ROD
ANODES
ELTECH Rod Anodes
are designed for application in:
- Process Vessels
- Water Condenser
Boxes
- Heat Exchangers
- Water Intake
Structures
- Groundbed
Applications
ELTECH Rod Anodes
are comprised of a titanium substrate with a mixed metal oxide coating.
The mixed metal oxide is a crystalline, electrically conductive coating
that activates the titanium and enables it to function as an anode.
Standard length is 4
ft, but the anodes may be custom cut to virtually any length. They are
available in the following diameters: 1/8", 1/4", 1/2", 3/4". Anode
coatings may be selected to match fresh water, brackish water, seawater,
coke, or sand environments. |

Anode
Life Data
Due to the
extremely low consumption rates and dimensional stability of mixed metal
oxide anodes, the electrical resistance of ELTECH Rod Anodes remains
essentially constant with time.
The high current
density capacity of ELTECH mixed metal oxide anodes has the added
advantage of allowing high current overloads for initial polarization
without causing harm to the anode.
