The CATIII is a unique system that replaces traditional coating methods to control rust. The CAT System leverages an optimal combination of voltage and frequency to provide maximum corrosion suppression in “free air” steel structures such as automobiles, Air conditioning, mobile plant, machinery and suitable fixed structures. We thank you for your interest in the CAT System Electronic Anti-Corrosion System.

About Us

CAT Systems has been the innovator in high performance Electronic Rust Protection products for 25+ years. The CATIII Electronic Rust Protection System is the very latest in technology, designed to stop rust in the harshest environmental conditions. Not only do our products protect against rust, they also significantly reduce the time, effort and cost associated with maintaining the condition of your vehicle. Our goal is to ensure that our products and service are the benchmark by which the competition is measured!

In Summary

Controlling rust or corrosion electronically is not a new technology. Cathodic protection systems have been used to control corrosion in ships, jetties, land based fixed structures like bridges, tanks and subterranean metal structures for over 100 years.

Advantages of CAT Rust Protection

There are many great reasons to choose a CAT.

  • All the metal on the vehicle or structure are reached, both inside and out. All the places where traditional (spray) coatings may be missing or not typically applied.
  • The process is good for a lifetime—unlike coatings which degrade over time and need constant re-application • The rust suppression is an ongoing process 24/7.
  • There is no risk of chemical leakage unlike coatings.
  • There is no odour – There is no danger to the environment.
  • There is no electronic interference – CAT is certified to comply Australian, US and European EMC regulations.
  • CAT can be transferred easily.
