'Solartech' still uses sunlight to produce distilled water from brackish or saline water. Sunlight is absorbed by the water and it evaporates. The water vapor condenses on the relative collar glass cover and the condensate-distilled water is collected by appropriate channels.'Solartech' still are the result of extensive design and development efforts aimed at eliminating various problems encountered with conventional design. For example, in 'Solartech' portable still, to eliminate scaling problems, the whole still (including the distilled water channels) is made in the form of an integral mold.'Solartech' still ensures a consistent supply of distilled water. These systems are offered in a basic portable configuration. A number of these portable stills can be easily interconnected when there are large requirements of distilled water varying from 2 LPD to 100 LPD.
