00-01: Design Features and their Affect on High Performance Fill

In the design of a high performance cooling tower fill, many design features must be considered to produce optimum performance. This paper will show laboratory test data and detail the effect on fill performance of the following items; Flute geometry (cross-corrugated, offset-tube, vertical tube), Cross-corrugated flute angle, Sheet pitch (19mm vs. 20mm vs. 17mm vs. 12mm), Microstructure (course, fine, none), Material (PVC & polypropylene), Module depth (12' layers vs. 24" layers vs. 48" layers), Tip design (Alternate tips vs. straight tips).
