How ERPS Works

To understand how the ERPS system works you first need to understand two underlying concepts:

  1. What is rust? Rust is the normal electrochemical process of metals slowly returning to their natural, unrefined state. It occurs when iron and oxygen combine. Moisture and salt increase the rate of the chemical reaction.
  2. Why does rust happen? Very simply stated, iron and oxygen have opposite charges so they seek each other out to combine. When they combine, the iron loses electrons to oxygen atoms. This is called oxidation and when it happens it produces a chemical reaction that causes rust.

So What Does ERPS Do?

Basically, the ERPS system interferes with the electrical charge between iron and oxygen so it becomes hard for them to combine to form rust.   ERPS uses a proprietary electronic "capacitive coupler" system to continuously replace lost electrons from the iron in vehicles and metal structures to prevent or reduce the rusting process.

The process goes like this:

  1. An Electron Generator the ERPS Power Unit transfers an output voltage to the ERPS electro-couplers.
  2. The ERPS electro-couplers become charged and act as the positive plate of a capacitor. An electron rich, negative charge is created on the vehicle's metal surface making it act as the negative plate. The paint acts as a dielectric, holding the charge static.
  3. Rust is caused by the loss of electrons from iron when iron and oxygen combine, but because the capacitor works to constantly replace lost electrons on the vehicle's body, rust is prevented or retarded.

Power Supply To The Couplers

The ERPS system operates a unique "closed loop" electrical circuit. This means that all couplers are connected to a common rail supply line. Although in the diagram they may appear to be wired in "series", this is not the case. All couplers are connected in a "parallel" plane ie: all couplers receive an equal amount of voltage or charge from the electron generator. This can easily be checked with a multimeter anywhere in the circuit.

The "closed loop" coupler circuit allows for complete monitoring of the coupler supply line, any fault in the circuit is immediately shown up and the LED light on the generator will go out indicating a fault. Once the fault is rectified the system will immediately "reset" and the operation returns to normal.
