ESA in the car
For years, corrosion is a major problem in the automotive industry, where the car body's sheet metal can be quickly destroyed by corrosion. There are several ways of protecting your car from corrosion. The first and probably the most popular and cheapest way is to cover the metal surface with a protective coating, including all kinds of paints and varnishes. However, you need to pay attention to the coating tightness. Every chip or damage will start the process of corrosion. In the 70's and 80's more expensive car bodies were immersed in tanks with anti-corrosion solution as in the case of Volvo. Unfortunately, the protection was effective only in places where the body of the car was not exposed to any mechanical action. As can be seen in many places, paint coatings are frayed or scratched by the working parts or all kinds of plastic elements or wires. Another fact is that the car body is working all the time as well, which can be frequently seen when you raise the car up using the car jack and you try to close or open the door. When the car body works, micro cracks in coating appear. These are disadvantages of this method of corrosion protection. After several years, a new era in the corrosion protection began. Nowadays much better, more efficient and cheaper method can be used - cathodic corrosion protection, which is now generally known as
galvanization. Steel surfaces are coated with zinc or hot-dip galvanized. This method is much more effective than conventional methods, there is no need to sealingly cover the metal surface. Zinc as a metal with a lower electric potential concentrates all the electrochemical reactions commonly known as corrosion or rust. Our devices work on the same principle of anticorrosive protection , they are an alternative to the cars without galvanic coating after accidents, and as an extra protection fter the warranty period when the zinc coating is worn off. Unfortunately, when the zinc coating is worn off because of being constantly exposed to corrosion, and when the car was repaired and the item hadn’t been pre-galvanized or the zinc layer was damaged during welding or grinding, those parts are prone to rapid corrosion.
Because of this we have created EAS active cathodic corrosion protection system where the polarization with the use of the electric current causes much greater difference between potentials and allows point installations. The presented device is designed to protect any vehicle with 12V power supply - because such voltage is
needed. The device is constructed in such a way that it is absolutely safe for the vehicle electronic system and all devices installed. Power consumption is minimal -12 mA.
The device is easy to install. The usually suggested places are the drain trough
under the hood and the tailgate.
There we screw or stick the electrodes. You will receive the installation instructions via e-mail after the purchase, and with the device in the package. It is also available in the "Installation" tab.
