Tecnoseal’s Hy-TEC® is a hybrid cathodic protection system composed of two sacrificial anodes and an active impressed current system. The development of this product derives from the need to equip small/medium sized hulls with a versatile cathodic protection system capable of guaranteeing more efficient protection in the intervals between one dry dock and another.
Hy-TEC® also has the function of “helping” traditional anodes in the first phase of polarization of the connected structures. The technology has been studied for applications on fiberglass and composite boats. An important feature of Hy-TEC® is its ability to work with Tecnoseal’s sacrificial anodes which are produced in the three alloys. This ensures the system works in salt, brackish and fresh water.
Hy-TEC® has the function of delivering the required current for cathodic protection of the metal parts connected to the system. It integrates the protection provided by sacrificial anodes during their natural consumption for the maintaining of the correct electrochemical potential.
The system is equipped with an integrated monitoring probe which constantly informs and regulates the control unit through voltage readings. When the values fall below a preset protection threshold (usually when the anodes have depleted) the booster comes into operation by delivering the necessary current required to protect all the metal parts against galvanic currents via the Ti-MMO plate.
The probe can also be connected with Tecnoseal’s ATOM® system for constant monitoring of the electrochemical protection potentials of the entire vessel. An additional and important function of Hy-TEC® is that the hybrid system provides acceleration of the polarization process of the connected structures. This significantly reduces the activation times expected from sacrificial anodes.
