CAT Electronic Rust Protection Systems

The CAT System is the Best Electronic Rust Protection System for motor vehicles in Australia and is a very popular and effective alternative rustproofing solution.

CAT Electronic Rust Protection Systems operate by “impressing” or “forcing” an alternating current (AC) of a specific waveform and frequency into the metallic body of the vehicle which interrupts the rusting process.

The CAT Electronic Rust Protection System is a high-quality product that uses the most advanced technology to protect your vehicle from rust and corrosion. It can work by itself or together with our spray-on coatings to create a powerful multi-layer rust protection solution for your vehicle.

Choose your System

For passenger 2WD & 4WD vehicles that mainly drive on sealed roads, we recommend using the "2 Coupler" System. If you occasionally go off-road, we suggest the "4 Coupler" System. For those who frequently operate their vehicle near saltwater or on the beach, the "6 Coupler" System is the ideal choice. For vehicles used in high-risk environments, such as mine sites or coastal/offshore facilities, we highly recommend the "8 Coupler" System.

I did an 8 pad system on a shipping container pond and all pretty straight forward with instructions and advice given. Expanded it to 10 pads and the additional stuff showed up just about the next day. This system is very easy to work with.

Key Features !

Purpose designed for Rust Suppression !

The CAT Electronic Anti-Corrosion System is purpose designed to suppress rust development in motor vehicles, trucks, buses, air conditioners and many other types of plant and machinery.

Auto-Switching 12V or 24V Operation !

The CAT System can function with either a 12VDC or 24VDC battery or power source, and it will automatically detect the input voltage and adjust its operation and diagnostics accordingly.

Modular Design - Easily Expandable

The Main Generator Module features two output circuits, with each circuit capable of powering up to 6 coupler pads connected in series (or a total of 12 Coupler Pads for both circuits). Furthermore, users can add extra coupler pads at any time to enhance the system's performance.

Shockproof and Waterproof !

The entire system, which includes the Main Control Module, Coupler Pads, Wiring Harness, and all connectors, is both shock and waterproof, surpassing IEC529, DIN40050, and IP67 standards.

Why Choose CAT ?

Not all electronic rust suppression systems are the same !

Only a "negative electrolysis" - "impressed current" system like CAT is capable of effectively preventing rust development in "free air structures" such as motor vehicles and mobile plant and machinery. You can rest assured that every component associated with CAT is of the highest quality, and nothing else in the world can match the performance of a CAT unit in protecting your assets.
