The industrial solar water heater system operates on the principle of selective surface absorption. The specially designed surface of the collector absorbs solar radiation and efficiently transfers the heat to the water flowing through the copper tubes. As the hot water, heated by the industrial solar water heater, is less dense, it rises to the insulated storage tank, and an equal volume of cold water replaces it in the copper tubes. With a solar water heater for industrial use, it is possible to achieve temperatures up to a maximum of 95 degrees Celsius. Industries such as Textile, Hospitality, Rubber, and Dairy sectors already utilize boilers for steam generation. The hot water from the solar system can be used as preheated water for these boilers, resulting in significant fuel savings of up to 30% to 40% on daily consumption of conventional fuels like LPG, Diesel, and Firewood.
