Cooling Towers nozzle is an efficient, non-clogging nozzle designed specifically for all counterflow cooling tower applications.
The design for this cooling tower nozzle provides excellent flow characteristics and a very uniform spray pattern, enhancing the cooling tower's thermal performance. The unique color coding system allows for easy identification of the correct orifice size, from .75″ to 1.5″.
This cooling tower nozzle is easily installed. It attaches to the distribution lateral with a PVC adapter using standard 2″ NPT threads. And the 2″ threads are available on request. The nozzle can be easily removed for cleaning or replacement.
This Cooling Towers nozzle is manufactured of inert high strength injection molded polypropylene for outstanding corrosion resistance. Gusseted teeth enhance the cooling tower nozzle's strength. Plus, the bottom plate locks into place for additional security.
Water Distribution
Of course, the most obvious impact of a nozzle is due to its primary job of getting the hot water to the fill. Ideally, 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. You've spent a "few dollars" to put fill into your cooling tower, so now you need to make sure that you utilize it to its fullest extent by making sure that it is totally wetted out and all sections of fill receive a constant amount of water. All published performance data for a fill is based upon this assumption.
Gaps in spray coverage can lead to air bypass because dry fill offers lower resistance to airflow, and air will always take the path of least resistance. This will result in airflow being stolen from wet fill sections where it is needed to cool the hot water. Also, since air and water are both fluids, the gaps are not 100% constant in their location. As the competing fluids interact with each other they tend to pulse and shift around. This causes some of the fill to experience alternating cycles of wet and dry times which will promote scale formation within the fill. As scale builds up in a fill it starts to adversely affect its thermal performance capability, and in the extreme, can totally block airflow from the fill and potentially cause structural damage to the cooling tower if the fill's weight gain from the scale is excessive.
Spray Zone
Another way that 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. The cooling effect in this spray zone can vary from 5-15% of the total cooling provided by the tower. The key to cooling here is to maximize the interaction between the hottest water and the coldest air. Thus, a nozzle that generates very small droplets will have a greater cooling effect than a nozzle that makes big, fat droplets. This is similar to the cooling effect of walking through a fine mist on a hot summer day as opposed to being hosed down by a fire hose.
