Film Type Filler

These types of fillers have the highest efficiency in their field. They are exposed to maximum airflow by spreading the water in a thin film layer over large vertical areas. Having a more effective cooling capacity in the same amount of cavities allows the tower dimensions to be reduced and energy consumption to decrease. Film fillers should be used in processes that have clean water.

How FilmType Filler works in water cooling towers ?

Film-type filler, also known as film fill, is a specific type of cooling tower fill media designed to enhance the efficiency of the heat exchange process. Film fill is widely used in water cooling towers due to its effectiveness in maximizing the contact surface area between water and air, allowing for efficient heat transfer. Here's how film-type filler works in water cooling towers:

Formation of a Thin Water Film: In a cooling tower equipped with film fill, hot water from industrial processes or HVAC systems is evenly distributed over the top of the fill sheets. The fill consists of closely spaced, vertical surfaces that allow the water to spread out and form a thin film.
Countercurrent Flow: As the water flows down the vertical surfaces of the film fill, it encounters a stream of air moving upward through the tower. This countercurrent flow allows for effective heat exchange.
Heat Transfer: The thin water film on the fill surfaces provides a large contact area for the air passing through the tower. Heat from the warm water is transferred to the air through the film of water by convection and evaporation. The heat causes a portion of the water to evaporate, absorbing heat energy and cooling the remaining water in the process.
Latent Heat of Vaporization: The process of water evaporation requires heat energy (latent heat of vaporization). By absorbing this heat, the water undergoes a phase change from liquid to vapor, which significantly cools down the remaining liquid water.
Cooled Water Collection: The cooled water, now at a lower temperature, collects at the bottom of the cooling tower basin and is recirculated back to the industrial process or HVAC system for further cooling.
Air Discharge: The warm, moisture-laden air exits the cooling tower through the top, and it is released into the atmosphere.

Film-type fill maximizes the surface area for heat transfer, allowing for efficient and effective cooling of the circulating water. The film fill's closely spaced vertical surfaces create turbulence in the air and enhance the interaction between the air and water, optimizing the cooling process. The efficiency of film fill in water cooling towers is influenced by factors such as the design of the fill sheets, the water flow rate, the air velocity, and the temperature and humidity of the ambient air. Proper selection and maintenance of film-type filler are essential to ensuring the cooling tower operates at its optimal efficiency.
