1. RSi Industrial Electronic Rust Protection A first in industrial corrosion control

2. New 6 Channel System - Drives 18 anodes Protects up to 200m 2 of Steel per system Multiple RSi systems can be connected in series for larger projects i.e. modular Anodes corrode and replaced after 2 years RSi Industrial

4. Only system to successfully combine both ERP technologies IMPRESSED CURRENT and SACRIFICIAL ANODE technologies

5. First we need to understand how rust forms. So how does stop rust ? RSi uses the same principal as our world famous vehicle electronic systems sold internationally for over 20 years

6. Any steel is made up of Iron Atoms (Fe) and Free Electrons. Pure steel would experience very little rust, but the reality is that recycled and low quality steel is used which contain many Impurity Atoms. Steel

7. The impurity atoms have a slightly POSITIVE (+) charge compared to the iron atoms (-). This voltage or potential difference averages at about 1.1 volts Steel

8. Because the Impurity Atoms are positively charged in relation to the Steel (Fe) and the Free Electrons are negatively charged, there is an attraction of Free Electrons towards the Impurity Atoms (positive attracts negative)

9. When there is moisture present, the moisture provides a path, or electrolyte, for the Free Electrons to move through and they then move freely towards and react with the Impurity Atoms. THIS REACTION IS KNOWN AS RUST

10. A Simplified Equation + Impurity Atoms IN THE STEEL + Water (H2O) = RUST Free Electrons (e) IN THE STEEL

11. RustStop® RustStop® uses both Sacrificial Anode and Impressed Current technologies RustStop® in an OFF state

12. The +45V charge on the anodes, causes a stronger attraction of Free Electrons than the Impurity Atom of only +1.1V. The Impressed Current then forces the Free Electrons away from the Impurity Atoms and towards the sacrificial anodes.

13. Effectively RUST needs Free Electrons in the steel to form. The Free Electrons are now diverted towards the RustStop® anodes. The anodes (Rust Magnets™) now corrode rather than the steel.

14. New Rust Magnet™Used Rust Magnet™ The RustStop RSi Anode Rust Magnets™ Corrode, not your Equipment New Rust Magnet™Used Rust Magnet™ Rust Magnets™ are replaced every few years

16. RSi Industrial Success Story: …had a serious problem with rust on their cooling pipes… …June 2006 we installed 5 x RustStop RSi systems. …over the next 2½ years these two areas were monitored…There was absolutely no sign of medium or severe rates of corrosion… “Our customer was very impressed…”
