How Does ERPS Work:

The Basic Version

The process of stopping rust electronically can be a little bit complicated at first (as it involved both electrical and chemical reaction)…but here’s the simple version:

1. Iron Rusts In Oxygen

Iron (the base element of steel) rusts when exposed to oxygen. As most vehicles, machinery and structures are above-ground this reaction is happening all the time.

2. ERPS Slows The Reaction

Basically, an ERPS system seeks to slow down the natural rusting process. It does this by supplying excess electrons to the Iron structure, which reduces the rate of rust.

3. Rusting Is Reduced

Though we get a lot of positive feedback of our systems 'stopping' rust - the truth is, rust will always occur. However, with the addition of a good ERPS the effects of rust can be dramatically reduced.

The Full Version (In 3-Simple Steps)

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 basic guide here or a more in-depth version here.

2. How does ERPS stop rust? 

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.

How does the system work?

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.
