Spray nozzles are key elements of evaporative cooling towers, but are often neglected. Many different nozzle types have been developed and are used in cooling towers worldwide. The spray patterns of eight different nozzles from the international cooling tower market were investigated inside a hall with the result that there are no nozzles available which provide an even water distribution as it is achieved in other industries. But uneven distribution leads to reduced cooling performance. Therefore, a new spary nozzle for cooling tower applications was developed in co-operation with leading spray nozzle experts over the last three years. Design details and distribution patterns will be presented.
