The autonomous device STOPCOR SOLAR is an anode for the solar water heater and consists of the device and its base. This device functions as a replacement for the external anode of the Stopcor Solar solar water heater. The base is not included, as it does not need to be replaced.

This is a standalone device that protects the solar water heater from electrochemical corrosion. It is installed externally, connects to the solar water heater, and protects it from rust and corrosion for a period of 2 years.

The STOPCOR cathodic protection method uses a magnesium anode and applies voltage through the sacrificial anode. This 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 mass of the magnesium and the second electrolytic pole (copper casing). The current is absolutely direct and suitable for application to other metals.
