Electronic Rust Protection — Engineered for Real-World Conditions

CAT electronic rust protection systems are used across automotive, industrial and commercial environments where corrosion management matters.

Designed for practical installation and long-term operation, CAT systems provide continuous electronic corrosion suppression that complements conventional coatings and treatments.

Whether installed by vehicle owners, workshops, or commercial operators, the goal remains the same — supporting corrosion management in environments where moisture, salt and contaminants accelerate deterioration.

CAT systems are distributed throughout Australia and supported by a nationwide stockist network.

Selecting the Right System

Selecting the right system is straightforward — system size is determined by operating environment and exposure level.

Mainly sealed-road driving
→ 2 Coupler System typically suitable

Occasional off-road use
→ 4 Coupler System recommended

Regular saltwater or beach exposure
→ 6 Coupler System generally preferred

High-risk environments
(industrial, mine sites, offshore/coastal facilities)
→ 8 Coupler System strongly recommended

When in doubt, selecting the larger system simply provides broader coverage !
