TP24-23 New High Performing Cooling Tower Film

The paper presents new developments of high performing cooling tower fill. The fill is of the foil type which creates an advantageous film flow and is preferably applied for counter flow cooling towers. For overall high cooling tower performance, a very good fill and a well performing water distribution system is the key. The best water distribution covers the complete cross sectional area of installed fill and creates evenness over this fill area which is mainly achieved by application of full cone nozzles. For further improvements, R&D has to be concentrated again on the fill design. There are a variety of different fill design types on the market. For counter flow applications fills with foil design have typically the best performance based on better water quality.
