Description
The CF-19 Cross Fluted Film Fill is engineered using an advanced inline foil-forming technique combined with a final thermo-welding assembly process, resulting in a highly durable and self-supporting structure. This method allows for adjustable foil thickness to meet specific customer requirements, providing enhanced material strength and application flexibility. With decades of successful performance across small, medium, and large cooling tower installations worldwide, the CF-19 ensures reliable efficiency with low pressure drop and optimized water-film distribution.
This high-performance trickle fill system stands out for its exceptional mechanical stability. Its strength is attributed not only to the robust welding technique used during fabrication but also to its unique structural configuration. Compared to outdated flat film fill types, the reinforced edge design of the CF-19 offers significantly improved load-bearing capacity and resistance to mechanical wear.
The CF-19 fill can be tailored to meet strength classes up to 80 kg/m³, ensuring the ideal structural characteristics for varying applications. Manufactured without the use of solvents, this environmentally responsible fill is compliant with key fire safety standards and supports both factory and on-site production through proprietary welding equipment. Its optimized design—featuring more than 97% free volume—makes it ideal for clean and lightly contaminated water, ensuring long-term performance and ease of maintenance.
The CF-19 is suitable for a wide range of industrial and environmental systems, including cooling towers, agriculture-based irrigation systems, and wastewater treatment facilities. Please contact our technical team to select the appropriate fill type for your specific needs.
