After Solar distillation
※Picture is illustration purpose
Change distilled water to delicious mineral water.
By passing through our sophisticated mineral unit, we can change distilled water to delicious mineral water.
Generate pure water with the power of the sun!!
We work for solving water and garbage problems by the use of DSW.
We developed ‘Solar Water’; solar heating device which produces drinking water and hot water simultaneously.
This is the first Solar Heater Water device in the world to generate distilled water which we can safely drink as drinking water by the use of solar heat. This product of ours is focused on highly on the world from the point of solving water problems and reducing the environmental load due to the consumption of pet bottles.
Large Capacity RSS Series
