2″ Variable Flow Nozzle – (Box of 24)


The Variable Flow Nozzle is a 2″ NPT threaded nozzle that is designed to work in counter flow cooling towers. The spring loaded design allows the orifice of the nozzle to adjust based on the pressure being supplied to the nozzle. The nozzle sprays in a 3' x 3' SQUARE pattern which provided uniform fill media coverage.

VFN Features

2″ NPT threaded nozzle with spring loaded orifice variability. Each nozzle sprays in a 3′ x 3′ square pattern. These nozzle ship in boxes of 24.

  • Square Pattern – Uniform spray pattern is #1 key to performance.
  • Close placement to fill media. Just 2″
  • Amazing Turndown Ratio – The nozzle maintains the same pattern from 50-150 gpm.
  • Spring loaded design allows for varying water pressures (huge benefit).

Performance Data

The VFN has been tested against a 9 nozzle configuration. This configuration is essentially a 1 nozzle per square foot approach and is used to canvas a fill media. This type of configuration serves as a bench mark comparison. Our setup uses 4 nozzle for every 9 square feet and it performs at nearly the same rate. The graph below shows the comparison.
