Alpha III fill (also knows as Alpha III Wing Foot) will increase cooling tower thermal performance capacity vs. wood lath in industrial towers. Variable fill bar spacing is available to provide the required thermal performance.
Alpha III fill bars are corrosion resistant PVC extrusions which are supported by FRP (fiberglass reinforced polyester) grids.
FRP fill grids are extremely inert and tough. Each fill bar is firmly attached to the FRP grid to prevent premature wear on either the grid or the fill bars. The fill bars are designed to prevent sagging, even after prolonged exposure to a cooling tower environment.
Alpha III is a direct replacement for many types of wood lath and ACB fill. The FRP grid can be manufactured to fit virtually any cooling tower regardless of its age or manufacturer.
The rounded upper surface of the fill bars and the smooth surface finish facilitate cleaning.
