Use the following information for approximating turbulator nozzle layout:
The orientation of the turbulator nozzles is not an exact science. There are too many variables, such as filtration flow rate and the pressure required to operate the nozzles effectively, to determine the "exact" number of nozzles and their appropriate placement. The goal is the adequate agitation and coverage of the cooling tower basin.
Proper installation and orientation of the turbulator nozzles result in effective basin agitation at nozzle pressure between 0.5 and 4 bar (10 to 50 psi).
Tips for Lateral and Manifold Placement:
Laterals near basin walls or obstructions should be located 0.6 meters (2 ft) from the wall/obstruction.
Place lateral against basin wall in very small basins where only one lateral is required.
For effective agitation, laterals should be elevated off the basin floor such that:
Manifolds and laterals should be anchored in place to prevent movement or flotation.
Tips for Turbulator Nozzle Placement and Orientation:
Nozzles should be evenly distributed along the laterals. Multiple laterals should be evenly spaced. Optimum spacing of the nozzles is 75% of the "Effective Flow Path" of the nozzle selected.
When possible, some nozzles should be directed towards the wall obstruction and corners to prevent settling there.
Nozzles should be oriented so debris is swept towards the pump intake point in the basin.
