Are all electronic rust-proofing systems the same?

No, we know different electronic rust-proofing systems.
Electronic rust-proofing has been around for more than 60 years in the form of cathodic protection devices (impressed current and sacrificial anodes) which were designed to protect boats from rust. As these devices are effective for their intended use only, they are not suitable for use on motor vehicles.

CouplerTec is acknowledged as the world’s leader in the design and manufacture of electronic rust-proofing systems for motor vehicles. CouplerTec systems use state-of-the-art capacitive coupling technology. This patented technology has been specifically developed to protect motor vehicles from rust.

There are, of course, also those providers of electronic rust-proofing systems who boast that their products perform at least as good as, if not better than, CouplerTec. You can verify their credibility yourself!

Only CouplerTec systems, which are internationally patented, meet the highest quality standards and have been thoroughly tested in both laboratories and the harshest natural environments, have been proven to be effective. All CouplerTec systems bear a unique number which distinguishes them from imitations.

There is only one CouplerTec original.
