Zinc Anode 620 Datasheet

Energizer Industrial 620 (EN95) Chemistry: Zinc Chloride (Heavy Duty) / Zinc Carbon Nominal Voltage: 1.5 Volts Typical Capacity: ~300 mAh (at low drain)

Below is a comprehensive technical breakdown of the specifications, applications, and installation guidelines for a standard 620-series zinc anode. ⚓ Zinc Anode 620 Technical Specifications

These anodes are often "pre-packaged" to ensure consistent performance in high-resistance soils: zinc anode 620 datasheet

Many Chinese and European manufacturers use "620" as a model number, not a dimension.

Engineers often debate whether to use Zinc or Aluminum for marine corrosion protection. Below is a comparison based on standard electrochemical data: Below is a comparison based on standard electrochemical

This product must meet demanding material standards to function effectively:

Do not apply anti-fouling paint, primer, or topcoats to the surface of the zinc anode. Painting isolates the zinc from the seawater, preventing the electrochemical reaction entirely. Replacement Schedule Approximately 11

: Approximately -1.10 Volts relative to a Cu/CuSO4 reference electrode.

Approximately 11.2 kg (24.7 lbs) per Ampere-year. Efficiency: ≥is greater than or equal to 95% in open seawater. 3. Physical and Mechanical Specifications

contains solvents and heavy metallic pigments, rigorous safety protocols must be followed during application:

Designed for operating temperatures under 50°C (122°F). At temperatures exceeding 60°C (140°F), zinc undergoes a potential reversal, becoming cathodic to steel, which accelerates the destruction of the steel structure. Typical Use Cases Ship hulls and thruster tunnels. Ballast tanks and sea chests. Offshore drilling platforms and jackets. Harbor piers, pilings, and lock gates. 5.
