Abstract

Apparatus for protecting submerged equipment from biogrowth. In one embodiment, a submerged, underwater ultrasonic transducer assembly is enclosed in an isolation chamber that contains a zone that is free of bio organisms. The isolating chamber encloses the transducer assembly to provide an outer surface exposed to the body of water where that outer surface is distanced sufficiently from the transducer assembly to ensure algae is inhibited from growing on the outer surface. The isolating chamber is a water-tight enclosure filled with a liquid. In another embodiment, the transducer assembly is surrounded by a light array that directs illumination toward the assembly. The illumination is at a wavelength that inhibits biogrowth. The light array includes a plurality of light strips with spaced apart lights. The light strips are supported by a bracket such that the transducer assembly is fully exposed to the illumination from the light strips.
