About

• Water distribution:Hot water enters the tower at the top and is distributed evenly over the fill media by a system of nozzles or holes in a hot water basin.
• Air intake:Fans, typically induced-draft axial type, draw air in from the sides of the tower through louvers.
• Heat exchange:The air travels horizontally across the fill media, coming into direct contact with the water. As the water falls, it breaks into smaller droplets or thin films on the fill, increasing the surface area for contact. Evaporation occurs, which cools the remaining water.
• Air and water exit:The now-warmed and moisture-laden air is then expelled from the top of the tower.
• Cooled water collection:The cooled water drips from the fill into a collection basin at the bottom of the tower and is then pumped back into the industrial process.

• Air and water flow:The defining feature is the perpendicular, or "cross," movement of air and water.
• Gravity-fed water distribution:Gravity is used to move the water down through the fill, eliminating the need for air to be forced through the water distribution system.
• Maintenance access:The large, open plenum area at the top of the tower provides easy access for inspection and maintenance of fans and other components.
• Design flexibility:The design is adaptable and suitable for a wide range of industries and water qualities, with customizable fill options available.
