Tank Ring Anode System

SPL™-Anode System for Above-Ground Storage Tanks (ASTs)

MATCOR has developed an accurate, reliable and easy to install impressed current cathodic protection system for the bottoms of above ground storage tanks (AST’s). MATCOR’s unique SPL-Anode system with patented Kynex® technology is manufactured in concentric rings and ready for installation on a specific tank.

Once designed and manufactured by MATCOR, installation is as easy as laying out the rings per a drawing provided by MATCOR and connecting the header cables to the rectifier. MATCOR Tank Ring Anode cathodic protection systems include:

  • Concentric SPL-Anode Rings manufactured to length and numbered for each position
  • Available in all current output sizes
  • MATCOR engineered anode placement with numbered anode rings
  • MMO Anodes used in the SPL-Anode assembly
  • Reliable Kynex® connection technology
  • MATCOR installation drawing indicating layout of SPL-Anode rings and reference electrodes

MATCOR engineers can also design and manufacture your complete tank farm cathodic protection system. There is no equal in cathodic protection.

Engineering Drawing »

Each MATCOR Tank Ring SPL-Anode System includes the concentric rings cut to length per the MATCOR drawing. Each SPL-Anode ring includes a sufficient length of cable on both ends of each segment to reach the rectifier or junction box without splicing.

MATCOR also recommends the following optional equipment for a complete installation:

  • MATCOR under tank CUSO4 reference electrodes with sufficient cable to run to the junction box or rectifier
  • Ground cables and reference electrodes
  • Rectifier and junction box

Tank Ring Anode System Design and Ordering
Contact MATCOR engineering to size the Tank Ring SPL-Anode System for your tank. MATCOR will determine the number and length of rings, recommended reference electrodes and cable. Simply order the system quoted and a complete, easy to install tank system will be shipped to your location.
