Everyone knows how important the fill is to a cooling tower's performance. Since fill is the heat transfer medium around which the “box” that is the cooling tower is built, you could argue that it's the most important factor in determining just how well your cooling tower performs. However, since the cooling tower spray nozzles are tasked with getting the hot water that you want to cool delivered to the fill, the nozzles also play a very important part in the duty of a tower. Cooling tower spray nozzles are involved in the following aspects of a cooling tower's performance evaluation.
1.Water Distribution:the nozzles are located and sized so that they provide a uniform pattern of water over the fill with no gaps between their spray areas.
2.Spray Zone: the spray system affects a cooling tower’s thermal performance is from the cooling that happens as soon as the water exits the nozzle and falls to the fill.
