Solar technology can be used to replace fossil fuels for Industrial process heating especially in sectors that use low- & medium-temperature (less than 120 oC) heat for processes such as washing, leaching (mining industry), drying, pre-heating of boiler feed water, pasteurization, cooking and so on. Flat plate Collectors and Evacuated Tube collectors are proven technologies in solar water heating in the domestic segment. Aspiration Energy, a leader in providing industrial solar thermal solutions has researched on both these technologies & evaluated their performance for industry scale utilization.
