ABSTRACT:
A cooling tower fill support grid assembly and method of use which includes multiple cooling tower assembly fill hangers, each having a grid pattern that defines multiple grid openings of selected size. In one embodiment an anchor rivet pin extends from the horizontal grid members upwardly and disproportionally spaced-apart from the vertical grid members, into each grid opening. The anchor rivet pins are located off-center on the horizontal grid members between respective vertical grid members for engaging elliptical splash fills that are inserted in the aligned grid openings of adjacent assembly fill hangers in a first configuration. Once so inserted, the elliptical splash fills are rotated ninety-degrees into contact and engagement with the anchor rivet pins in a second, installed configuration. In another embodiment resilient, perforated plate splash fills are seated in the fill hangers and are removably retained between the respective vertical grid members by notches or nibs provided in or on the vertical grid members. The top edge of each assembly fill hanger typically has a notched flange for stacking and seating on the cooling tower frame and holes are provided in the flange for receiving nails.
