What is a cover ball? How does it work? What can it be used for? What are the benefits of using it? Where and for which areas can these balls be used effectively? These are all questions we often encounter in our work, so we try to answer them. ### Where and for which areas can these balls be used effectively? - airports - mines - sewage treatment and wastewater plants - drinking water reservoirs - fish ponds - fire water reservoirs - irrigation reservoirs - hazardous substances and chemical tanks - heated or cooled open surface tanks - livestock farms, slurry pits and lagoons ### ### What are the benefits of using it? - covers 91% of the surface - wind resistance up to 150 km/h - requires no maintenance - 10 years warranty - Evaporation of liquids can be reduced by up to 90% - disguises and hides the open water surface from birds - quick and easy installation - spread automatically as the liquid level rise and fall - thermal insulation layer – heating costs can be reduced by up to 75% - reduction of oxygen absorption - excellent chemical resistance - UV stabilized base material – weather resilient - less light enters the liquid, resulting in making worse living environment conditions for algae and plants, that cause degraded water quality - allows movement or immersing of equipment in the liquid - toxic gases, vapors and unpleasant odors are reduced, which ensures increased life expectancy of building structures and has better environmental affect - more stable temperature of liquid; smaller temperature extremes in cold or hot weather ### What is a cover ball? The cover ball is a hollow high quality plastic ball that can be used to create a continuous cover layer on the surface of liquids. Depending on the amount of balls placed on a given surface, they can cover up 91% of the surface in a regular shape, self-arranging next to each other. This cover layer separates and isolates the open surface of the liquid from its surroundings, i.e. it significantly reduces the effect of the liquid on the environment and vice versa. In English, several names are used for these balls, often referred to as ‘shade ball’, ‘cover ball’, ‘armor ball’, ‘barrier ball’, or ‘bird ball’. We, as a proud European Manufacturer, call them cover ball and Bird Ball™. [VIEW OUR PRODUCTS](https://euro-matic.eu/in/en/shop/?category=cover-balls) ### How does it work? What can it be used for?
