Abstract: The present invention involves a fill consisting of a plurality of plates that are preassembled into fill packs for application as fill media in cooling towers. A unique spacing and fastening system is employed to assemble individual plates into fill packs. The spacing system of the current invention utilizes a tube or rod which traverses apertures in the plates of the fill pack. The tube or rod is flattened or expanded in the area between the fill plates, thus locking the fill plates in place. The spacing system of the current invention provides substantially complete adjustability of the pitch of the fill plates. Alternatively, plate spacing can be effected by employing integral protrusions which bond to adjacent plates. The plates are designed to deploy a large amount of surface area in a compact volume and to allow free flow of fluids through the media. The plates utilize a ribbed structure which creates a relatively high strength-to-weight ratio for the individual plates.
