Autonomous device for protecting solar water heaters from electrochemical corrosion. It is installed externally, connected to your solar water heater, and protects it from rust, corrosion, etc.

The autonomous device STOPCOR SOLAR is an anode for the solar water heater and consists of the device and its base.

With the STOPCOR cathodic protection method using a magnesium anode, voltage is imposed through the sacrificial anode. The imposed voltage covers and protects large metal surfaces with a much smaller sacrificial mass of active metal (anode). The imposed current is generated by the transfer of ions due to the potential difference between the magnesium mass and the second electrolytic pole (copper casing). The current is absolutely continuous and compatible for imposing on other metals because it is generated naturally. It charges the protected metals negatively, absolutely satisfactorily, and while the surface was the anode of a galvanic element, i.e., a negative oxidative pole, it becomes the cathode of an electrolytic cell, i.e., a negative reductive pole. The protected surface remains negatively charged, but its action is reversed, and it tends to undergo reduction rather than oxidation. The imposed voltage must be above 1 volt and the intensity above 10 mA.

Advantages

• External installation
• Easy installation
• Has a replaceable part that can be easily changed without replacing the base
• The device is autonomous and does not require an external power source to operate.
• The imposed voltage is distributed throughout the installation and protects it overall.
• Does not pollute the environment and is absolutely safe.
• Unaffected by any weather or other phenomena
• Does not come into contact with liquids or, if connected to a water supply network, does not come into contact with drinking water.
• Provides stable voltage and intensity throughout its lifespan.
• Provides long-term protection.
• Economically affordable due to low manufacturing cost.
• Does not require special technical knowledge for installation.
• Does not require intervention, correction, or modification in the installations where it is placed.
• Provides cathodic protection absolutely compatible with metals because the voltage is generated naturally.
• Protects large surfaces compared to other methods.
