The orifice cap is available in 13 diameters ranging from .362 through 1.099. This amount of flexibility allows for a wide range of adjustment in water flow rates and basin water levels.
The Spiral Target nozzle is available in three lengths. The 2.625 nozzle is used on wood, steel, and fiberglass cooling towers where basin support structure does not obstruct the release of water. The 4.875 nozzle is used on larger industrial wood and concrete cooling towers and on applications where clogging might be a concern. The 6.875 nozzle is used on towers where the release of the water has to clear obstructions within the tower structure.
In every application the target portion of the nozzle should be located at the correct distance above the top of the cooling tower fill to obtain maximum water distribution over the fill area.
