A fanless cooling tower uses natural convection and evaporative cooling (like fine water mist) instead of mechanical fans to cool industrial water, relying on air buoyancy and specialized nozzles for passive airflow, making it energy-efficient, quiet, and low-maintenance with zero power costs for operation. These 'fill-less' systems, often made from FRP, eliminate fan/motor costs and maintenance, using aerodynamic louvers to draw in fresh air for cooling via water atomization.
