What Is Cooling Tower Fill?
Cooling-tower fill (also called fill media) is the core internal component of an evaporative cooling tower. It greatly increases the surface area and the contact time between water and air, allowing heat to be transferred more efficiently. Fill is typically made from PVC, PP, or UPVC formed into structured patterns or splashed grid designs.
Cooling tower fill works by increasing the contact surface and contact time between water and air, allowing heat to be transferred more efficiently. As warm water flows over the fill material, it spreads into thin films or droplets, greatly enlarging the surface area. Air is simultaneously drawn or forced through the tower, moving across this expanded water surface. Through direct heat exchange and partial evaporation, the water releases heat to the air. By the time the water reaches the bottom of the tower, its temperature has been significantly reduced, improving the overall cooling efficiency of the system.
1.Water Distribution
Hot water from industrial processes or HVAC systems is distributed over the fill through spray nozzles or distribution basins. The fill spreads the water into thin films or droplets.
2.Surface Area Enhancement
The fill provides a large surface area that allows water to spread out as thin layers (film fill) or break into small droplets (splash fill). This increases the total contact area between the water and the air.
3.Air–Water Contact
Air is drawn or pushed through the tower (either naturally or by fans) and flows across or upward through the fill. As the water and air interact over a large surface, heat and mass transfer occur.
4.Heat Transfer
4.1.Sensible heat transfer:
Heat moves directly from the warm water to the cooler air.
4.2.Evaporative cooling:
A small portion of the water evaporates into the air. This phase change removes significant heat from the remaining water, lowering its temperature. Evaporative cooling is the main mechanism of temperature reduction.
5.Cooled Water Collection
After passing through the fill, the cooled water falls into the cold-water basin at the bottom of the tower and is recirculated back into the system.

Why Is Cooling Tower Fill Popular In The Italy Market
The popularity of cooling tower fill in the Italian market is mainly due to the continuous increase in demand for efficient refrigeration in commercial buildings, industrial facilities, and rapidly growing data centers in Italy. Evaporative cooling towers rely on high-quality fill to improve heat transfer efficiency, save energy, and reduce operating costs; At the same time, under the pressure of energy conservation and emission reduction, water resource management, and maintenance optimization, many companies tend to improve the performance of existing cooling towers by replacing or upgrading fills, making fills one of the key components with the highest return on investment and most stable demand in Italian refrigeration systems.
