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