Presentation Transcript

  1. Nozzle Technology • Nozzles designed to reduce drift • Improved drop size control • Emphasis on ‘Spray Quality’

  2. Nozzles are important because: • Control the amount – GPA. • Determine uniformity of application. • Affects the coverage. • Influences the drift potential.

  3. Spray Characteristics are Important to Understand: 110o 80o Demonstrates Turbo Flat vs TurboDrop-5 MPH Wind

  4. Nozzles Types?

  5. Extended Range Flat-fan: • Tapered edge pattern • 80 and 110 degree fan • Requires overlap - 50 to 60% • 15-60 psi range 80° 110°

  6. Nozzles Types?

  7. Turbo Flat-fan: • Turbulence chamber • Tapered edge, wide angle flat pattern • Designed to work in flat-fan nozzle holder • Uniform spray distribution, 50-60% overlap • Wide pressure range, 15 – 90 psi • Large, drift resistant droplets • Plastic with superior wear characteristics XR TT

  8. Nozzles Types?

  9. Air-Induction/Venturi Nozzles Air is drawn into the nozzle cavity Exits with the fluid.

  10. Air/Induction – Venturi Nozzle: Spraying Systems AI TeeJet Air intake venturi section Mixing Chamber - air and spray solution blended Exit orifice Better Penetration? Improved coverage? Reduced drift? YES!!!

  11. Air/Induction – Venturi Nozzle: • Greenleaf – TurboDrop • Air intake venturi section • Mixing Chamber - air and spray solution blended • Pattern tip forms large air-bubble drops

  12. XR Turbo Flat-fan compared to A.I. XR vs TurboDrop Turbo Flat vs TurboDrop

  13. Driftable Droplets: Spraying Systems-2000

  14. Final thoughts: • Due to weather, all nozzle produce small droplets • high temperature, low humidity = smaller drops • evaporation • Match nozzle to pest – watch for drift • Venturi tips • Good for systemic or contact herbicides. • Performance over a wide range of pressures • Minimize spray drift potential • Maximizing performance.
