Low power consumption makes for fast mothballing and reactivation
Typical results after twelve months service in a box cooler installation are shown below. Photographed from the bottom of the sea chest looking upwards, the red surfaces visible are the sides and top of the sea-chest with the seawater inlet grate visible to the right.
All of these surfaces have been kept fouling-free by two Sonihull ultrasound transducers. A third transducer was mounted on the water cover of the right-hand box cooler, which also remains clear of any fouling. The left-hand box cooler was not fitted with a transducer and has fouled-up considerably.
