Electronic Rust Prevention FAQs
Here are the answers to some common questions about ERPS:
Frequently asked questions
A. It is often a difficult concept for people to understand at first how an electrical charge can stop or retard rust. This is not, however, a new concept , early studies date back as far as the early 1800's. In the 1920's and 30's electrical charge began to be used widely as a form of protection on steel gas pipelines/ Adapted in the mid 1980's for automotive use, electronic rust prevention has proven itself in some of the harshest environments on the planet. Working with commercial beach fisherman, who drive their vehicles into the ocean on a daily basis, ERPS has see dramatic reduction in rust, a reduction in maintenance costs and a dramatic increase in the resale value of the vehicle.
A. In short, "No". ERPS uses Capacitive Coupling technology a system proven in the harshest of conditions for over twenty years. Having pioneered electronic rust prevention in Australia, ERPS has the runs on the board with countless success stories and thousands of satisfied customers both in Australia and around the globe.
A. No, the ERPS system has passed both European & Australian Standard 4251.1 for electromagnetic compliance. This means that it will have no effect on any device or interfere with radio signal, ermergency channels etc.
A: No, the system draws less than 20 milliamps which is less than the power to run the digital clock on your dashboard. This means the ERPS system can run constantly without interruption, protecting the vehicle at all times day and night.
A. Spray on coatings only protect the particular area they cover, they are prone to being worn off and need to be maintained on a regular basis. ERPS covers the entire body of the vehicle including all the hidden and hard to reach places. The ERPS system has no wear components and other than occasionally checking the LED light, requires no maintenance. The ERPS system can also be transferred when updating your vehicle.
A: Yes the principal of operation works the same for both old and new vehicles. It works to slow the rate at which the steel reacts with environmental elements which cause rust. Hence, whether your vehicle is new or already has some rust, the ERPS system will work to slow the rust reaction and extend the life of the vehicle. With older vehicles it is recommended that the ERPS system be installed some four to six weeks before any rust repairs are undertaken. This allows the system to react with or neutralise any rust currently in the vehicle.
A: Yes, the main component of the system, the electron generator, can be removed and used on the new vehicle. New couplers and the connecting wire will need to be purchased to complete the installation.
A: ERPS uses solid state electronics with no moving parts or maintainable components. Therefore you can expect many years of trouble free operation. All ERPS systems come with a five year warranty against faulty parts or workmanship.
A: The Electron Generator houses a small, red, LED light. This red light should be checked on a monthly basis and should be constantly illuminated at all times. If the red light is not illuminated return the vehicle to a Registered ERPS Installer for inspection or follow the Trouble Shooting section of the Installation Instruction Manual.
A: With aluminium panels the system works in exactly the same manner as with a steel panel, slowing the oxidisation process. As long as the aluminium is painted the system will set up a negative charge on that panel. Wherever two or more dissimilar metals come in contact with each other in the presence of an electrolyte (eg: water), a small galvanic cell is produced causing rapid acceleration of corrosion. This is the case with the Land Rover where you have both steel and aluminium in close proximity, the system will however counteract this effect by inducing a negative charge to work against the galvanic reaction.
A. Because the galvanised surface is conductive the system's charge will dissipate into the atmosphere. For the ERPS system to operate correctly the galvanised surface must be painted. The paint acts as an insulator holding the charge onto the surface of the steel.
A: Yes, the system can be mounted directly onto the trailer. The Electron generator can be powered by a 12 volt supply from the towing vehicle or can be plugged into the mains supply via an AC adaptor when the trailer is not in use. If necessary the system can also be powered from a motorcycle battery and a small (5 Watt) solar panel.
