How Does Electronic Rust Protection (ERPS) Work?
The process of electronic rust protection can be a little complicated at first as it involves both electrical and chemical properties. To make things a little easier, we’ve created this 3-part video series to explain each part of the process. If you’re looking for more in-depth information you can find the written explanation below.

1.What is rust and how does it form?
Before we outline a solution, it’s important to understand the problem or question at hand. Basically, Iron loses electrons when it combines with oxygen and rust forms (moisture and salt increase the rate of reaction). For more details on this, you can check out our full article on rusting here.
2. What electronic rust protection does:
The process of rusting is a naturally occurring chemical reaction, with electrical properties. Simply put, electrons escape from unprotected metal, combine with atmospheric molecules and rust begins.
The ERPS system applies a negative charge to the body of the vehicle.
As a negative charge is electron rich, it replaces lost electrons to the steel which slows or prevents rust by lowering the metal’s voltage potential.
As a result, the metal becomes less reactive and therefore less likely to corrode.
3. How electronic rust protection works:
The ERPS system consists of an Electron Generator that is attached to a series of Electro-Couplers.
- Generator – Hard wired to the vehicle battery, drawing a small current (approx 20 milliamps).
- Couplers – The distribution point for the charge.
The Electron Generator steps up the battery voltage and transfers this charge to the electro couplers. The couplers become charged and act as the positive plate of a capacitor, whilst the vehicle structure is induced to act as the negative side of a capacitor.
This simple capacitive effect caused by the ERPS generator and couplers causes the metal of the vehicle to become negatively charged. A negative charge is electron rich, thus supplying an excess of electrons to the body of the vehicle, slowing or stopping the rust reaction.
Though the process of rusting and prevention can be somewhat complicated, we hope to make things as simple as possible for our customers. For more information regarding our system, you can check out our Information or FAQ pages, or for more complex queries, you can contact us directly here:
