Open Circuit Cooling Towers

KTC cooling towers utilise a water distribution system to spray hot water into droplets or a water film. Water flows downward through the fill material while air moves upward or horizontally through the fill. This process harnesses water evaporation and heat transfer between cool air and hot water to dissipate waste heat from the water, enabling the reuse of circulating water in industrial applications. Operating Process: High-temperature water is conveyed to the top of the open cooling tower, where it is uniformly sprayed onto the fill layer via nozzles. Within the fill, the water forms a thin film. Concurrently, air enters the tower through inlets at the base, passing through the fill to ensure thorough contact between water and air. During this interaction, the water evaporates, lowering its temperature while simultaneously humidifying the air. The cooled water then flows back to the pump via the sump at the tower base, ready for recirculation.
