The Double Oblique Wave Splash Fill is designed based on the step wave pattern, taking into account the cooling water flow path length of existing cooling tower fills in China. It significantly increases the actual flow path of cooling water, markedly improving cooling efficiency. Simultaneously, it ensures more uniform water film distribution, enlarges the water-air contact area, and slows down water flow velocity. This type of fill assembly boasts high strength and is widely suitable for natural draft cooling towers and large mechanical draft cooling towers.
