Vertical Anodes

Vertical Anodes

CerAnode’s WST Vertical Water Tank Anode is an impressed-current MMO mixed-metal-oxide anode system designed to be suspended from the tank roof and delivered throughout the water column for full-height protection of vertical storage tanks. It provides predictable, even polarization from top to bottom so walls, seams and welds are protected across the tank depth.

The assembly uses a robust MMO-coated titanium core and factory-prepared terminations and leads for dependable long-life performance in potable, brackish and seawater environments. Vertical WSTs are commonly used where wall corrosion risk is significant or where floor-laid anodes can’t reach mid-height areas.

Key Features & Benefits

Materials & Construction:

• MMO-Coated Titanium Core: Provides a low-consumption, catalytic surface for long design life and consistent anode performance.
• High-Strength Wire: Solid titanium or copper-cored titanium resists mechanical stress and supports suspension without stretch or breakage.
• Factory Terminated Leads: Pre-assembled terminations reduce field work and ensure low-resistance, watertight connections at installation.

Electrical & Performance:

• Uniform Vertical Polarization: protects walls, weld seams and intermediate elevations that horizontal systems may miss.
• Power Efficient: MMO coatings and correct spacing minimize rectifier load and groundbed losses.
• Scalable Current Rating: Choose wire diameter, coating rating and number of vertical strings to meet calculated current requirements.

Durability & Environment:

• Potable-Water Safe: Safe for use in potable and process water tanks when specified for that application.
• Biofouling & Corrosion Resistant: Resist degradation in freshwater, brackish and marine environments.
• Long Service Life: Engineered to multi-decade service when sized and installed per cathodic protection (CP) design.

Applications

• Vertical, cylindrical municipal and industrial water storage tanks (potable and process).
• Tall fire-suppression and standpipe tanks where wall protection is required at all elevations.
• Fuel or product tanks where internal anodes are preferred to external groundbeds.
• Tanks with internal coatings that require close-proximity impressed-current cathodic protection (ICCP) assistance.
