Cross Flow Cooling Towers

The basic function of a cooling tower is to transfer heat from hot water or other process fluids to the surrounding air through evaporation. In a cross-flow cooling tower, the water to be cooled is distributed over the fill material in the tower, which is usually made of PVC or other plastic materials. As the water flows down through the fill material, air is drawn across the fill by fans located at the top of the tower. This air flow creates a pressure drop across the fill, which allows the water to evaporate and release its heat to the air.

The cooled water then collects in a basin at the bottom of the tower and is pumped back to the process for reuse. The warm, humid air leaving the tower is typically discharged into the atmosphere or ducted to other areas for further processing or treatment. Cross-flow cooling towers are typically less expensive and easier to maintain than other types of cooling towers, such as counterflow towers, which have a more complex design. They are also more space-efficient than other types of cooling towers, making them ideal for applications where space is limited.
