What this listed product is
Seawater cooling-water zinc anode is an individually listed product form in the Zinc alloy sacrificial anodes range. It is presented for cathodic protection procurement and project discussion, with final configuration confirmed against the protected asset and project documents.
Series boundary
The series groups zinc alloy anode forms. Medium, geometry and installation conditions must be considered together; a model name alone is not a complete selection basis.
Fields to confirm
The product form, dimensions, connection method and installation interface should be checked together. Seawater cooling-water zinc anode should not be selected from a name alone when the protected structure, medium or installation position is not yet known.

Note 1: The reference electrode is a saturated calomel electrode.
Note 2: Use artificial or natural seawater. Use moist soil with backfill material added around the anode. Use natural sea mud or a simulated electrolyte. The media are at ambient temperature.
Note 3: The operating current density is 1 mA/cm in seawater and sea mud, and 0.03 mA/cm in soil.
