CCS cooling towers are custom-designed to fit your exact project requirements. Our ThermaFit™ software will help you decide which is best for your project - crossflow or counterflow.
The fill media is located inside the upper portion of the tower on a horizontal plane; air enters the tower below the media through side inlets and is pulled upwards through the media, "counter" to the downward flow of water.
Water enters from the top, cooling as it passes downward through the fill. Air enters the fill from below, across the bottom of the tower, where the air is also coolest and dryer. Heat transfer is generally considered optimized over that of a crossflow tower.
The hot water inlet is at the top of the tower and water is distributed over the fill media via pressurized spray heads, increasing pumping energy requirements.
Air is in contact with water longer, which requires less air motion to attain required airflow across the media to optimize heat transfer.
Hot water is distributed evenly over fill media with network of lateral pipes and spray heads in a more closed environment, less prone to contamination from outside dirt and debris.
Because of generally optimized heat transfer characteristics and lower fan requirements, Counterflow designs tend to have a smaller footprint. These towers are often selected for retrofit for this reason.
The fill media is generally located vertically along the sides of the tower. Air flows into the tower from side inlets, immediately passing through the fill, "crossing" the downward flow of water.
Water enters from the top, cooling as it passes downward through the fill. Air enters from the side and interacts with a cross-section of the entire flow of water, from coolest at the bottom to warmest at the top, so heat transfer performance varies.
A lower hot water inlet and usually gravity-fed water distribution lowers pump head requirements and energy consumption. Many high-volume applications use crossflow towers for this reason.
Size for size, requires more airflow, larger fans and more inlet area to maximize heat transfer.
Water feeds generally via gravity through a series of holes from an upper basin. Open systems can be more prone to algae and scale (although our basin covers help limit this) and require more water treatment.
Crossflow designs tend to require a larger footprint, but CCS can design a tower to fit your footprint by easily modifying tower design variables other manufacturers can't.
