For over 30 years, Anotec has been crafting the world’s best high silicon cast iron anodes.  Farwest represents Anotec as a distributor and licensed manufacture and custom builds the Anotec line of anodes.

The Anotec proprietary chill cast process assures consistent weight and a superior (stronger) microstructure, combating corrosion and outperforming the competition by up to 20%. 


  • Accelerated corrosion tests confirm that Anotec chill cast anodes yield more ampere-years per pound than the competition

Anode Composition

  • High Silicon Cast Iron

Chill Cast in Static Metal Molds

  • Anotec’s proprietary chill casting process assures a solid stick anode that will outperform the competition.
  • Can withstand drop impact tests to more than twice the height of sand cast anodes.

NSF 61 Listed

  • Safe for use in potable water applications.

ISO 9001 Quality Control

  • Anodes are manufactured, inspected, and tested in accordance with stringent procedures to ensure high quality.

Typical ANOTEC Anode Cross Section

A dense skin of minute columnar grains and a dense core of equiaxial grains. Occasionally, very fine interdendritic porosity at center. Predominantly spheroidal shaped graphite. Similar to the structure of vacuum refined High Silicon Iron.

Typical Cross Section of a Conventional Sand Cast Anode

Skin of nonporous equiaxial grains. Remaining section relatively porous from interdendritic shrinkage and porosity. Predominantly flake graphite with larger boundary areas than equivalent spheroidal graphite.
