In simple terms, rust develops because of a loss of electrons from the steel surface. By creating a negative charge on the surface of the steel (a negative charge being electron rich) we replace those electrons being lost and also create an excess. Thus slowing down the electro-chemical reaction of the rusting process.
The ERPS system operates a unique “closed loop” electrical circuit. This means that all couplers are connected to a common rail supply line.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.
