  • Apparatus for controlling marine fouling of salt water coolant heat exchangers, piping systems, and the like
    Patent number: 3984302
    Abstract: Marine fouling of the tubes of heat exchangers, piping conduits, and like apparatus through which sea water flows is controlled with the aid of an assembly mounted in situ within the system at the inlet ends of the tubes which generates chlorine gas by electrolytic action. The chlorine gas is distributed by the flowing sea water through the tubes and prevents the accumulation of marine plant and animal material on the internal surface of the tubes, thus controlling marine fouling.
