TELPRO POINT SOURCE DISCRETE ANODES
TELPRO Mixed Metal Oxide Activated Tubular Point Source
Anodes are manufactured using titanium, which meets ASTM B338 Grade 1 or Grade 2 standards, which has been coated with TELPRO Mixed Metal Oxide coating.
TELPRO MMO coating applied to the titanium substrate has been
designed for use in all cathodic protection applications. TELPRO
coating consists of IrO2/Ta2O5 and is suitable for use in soils,
freshwater, brackish water and seawater. Because mixed metal
oxide anodes have an extremely low consumption rate, the titanium substrate used remains constant throughout the design life of the
Based upon accelerated life testing, conducted by an independent
laboratory, TELPRO MMO coating has been proven to be equivalent or superior to other mixed metal oxide coatings which are currently being used; a copy of this test report is available upon request.
Strict quality control procedures are followed throughout the entire coating process, to guarantee proper coating adhesion and loading. Also, TELPRO products are tested using an X-Ray Fluorescence Spectrometer, to ensure production of the highest quality product, which is fundamental in every step of the manufacturing process.
TELPRO MMO Oxide Activated Tubular Point Source Anodes can be self-gas venting or supplied with venting holes, plastic end-caps and a PVC venting tube. These anodes can also be supplied with a spot welded titanium conductor bar, typically manufactured of titanium ribbon, 0.25” (6.35mm) by 0.025” (.635mm), which can be either coated or uncoated, and of a length appropriate to suit project requirements.
The current output of the anode is calculated by multiplying the
anode surface area x design current density, which typically can vary 110mA/m2 to 900mA/m2, subject to design factors such as gas venting, acidic attack on concrete, life of system, etc.
Normal Design Life for the point source anode is typically 50 plus
years when operating at an anode current density of 900mA/m2.
Coating loading can be adjusted for any combination of current
output and design life.
Working Environment: Evolution of O2, Cl2 or combination of both.
