Cooling

It's a breeze.

Cooling can enhance the color of apples.
Cooling can enhance the color of apples.

No heat is too intimidating for a Nelson sprinkler cooling system.

Cool your crop to enhance color and prevent damage from excessive heat. The Nelson sprinkler line covers many flow rates and droplet size options for a wide range of cooling needs, including very low application rates. The sprinkler models S7, R7, R5, R10, R10T, R2000LP, and R33LP all have fast rotation speeds, which is key for crop cooling. Rotator® Sprinklers lack vibration, allowing for the full spectrum of mounting options. Quick-connect and acme connections ease nozzle cleaning. The Nelson Mini Drain Check works with each Rotator model and prevents drain-down for rapid cycle systems.

Cooling the air provides only a small benefit, so uniform wetting is crucial.

Tips for sprinkler cooling.

  • Distribute water uniformly. Fruit is not cooled unless it is wetted fully and evenly. 
  • Automate zones using TWIG® Wireless Automation to run in short on-and-off cycles of 10 to 20 minutes.
  • Have an application rate high enough to prevent buildup of salts (Ca, Mg, Na, K), which can burn vegetation.
  • Install Nelson Drain Checks to prevent system drain down when cycling on and off.
