Sepehr Electric water coolers have a license to use Iran's standard mark. The metal parts are made of special high-thickness galvanized sheets from Thyssen Germany, which are resistant to moisture and corrosion.

The prominent feature of this cooler pad is its cellulose. The cellulosic pad has a uniform structure that creates a very large contact surface between water and air. Cellulose pad has a high water absorption capacity and can absorb water like a drying paper and remain moist in front of the air. By passing through the cellulose pad, the hot and dry air gives its heat to the water so that it evaporates completely and cool and comfortable air is created. The evaporation process in cellulose pads produces pure water vapor that is free of impurities and minerals.
