If you have reasons to suspect that there could be a risk of galvanic corrosion aboard,this special sacrificial zinc anode for the SPskin fitting should be fitted. Should there be considerable attack and material loss of the anode during a season, the reason for this must be found.
The risk of corrosion must always be kept in mind. So-called "noble" metals should always be used for those components which, if they fail, would cause serious damage; when mixing materials consideration must be given to their position on the electro-magnetic scale; always fit a sacrificial zinc anode which compensate for the difference in potential. The electrical system of your boat must be checked regularly for current leakage. All Isotherm units have a separate earth and are carefully inspected during production for current leaks. The heat exchanger coil of SP is made of a copper/nickel alloy and the skin fitting itself of dezincification-resistant annealed brass certified by Lloyds. The hard-soldering of the connections is in silver.
