A fanless cooling tower is a cooling system that works without fans. It cools hot water by using natural air movement and evaporation. As warm water flows down inside the tower, some of it evaporates, which takes away heat and cools the remaining water. The cooled water is then reused in industrial machines, air conditioning systems, or power plants. Since there are no fans, this system saves electricity, makes less noise, and requires less maintenance, making it an eco-friendly and cost-effective cooling solution.
