PVC Film Fill

PVC film fill provides the heat transfer surface required for water-to-air exchange in cooling towers. Sheets are vacuum-formed and assembled into blocks (bales) for installation. It is typically used in clean-water processes up to 55 °C, where water is free of excessive dust, dirt and scaling. Due to its large surface area, efficiency is higher than many other fill types. Common types include CF-12, CF-19, CF-30, CF-M and CF-O. CF-30 is widely used in wastewater treatment (especially biological treatment); CF-O is used in crossflow cooling towers.
