Abstract: A floating device to be used in groups to form a floating cover that floats over volumes of water or liquids used in industry, mining and agriculture, directed to reduce evaporation, algae formation and gas emanation. The device comprising an outer shell consisting of outwardly convex covers and lateral edges that have a polygonal shape in a plan view, vertical wall surfaces extending from the edges of the covers, wherein each vertical wall surface joins at the level of the middle plane of the device with the edges of an inner shell.
