Spiral Spray Nozzles

The original BETE spiral nozzle design is also called a pigtail, corkscrew, or helix nozzle. The spiral produces relatively coarse droplets surrounded by wider bands of relatively fine droplets. Ideal for quenching, scrubbing, and evaporative cooling.

The Original BETE TF Spiral Nozzle Design

Discover the TF spiral nozzle invented by BETE. The durable one-piece design of the TF is resistant to clogging and has a high discharge velocity. Spiral nozzles feature efficient spray performance for finer atomization. The TF offers a wide range of flow rates and spray angles.

Customers trust the reliability of BETE’s TF spiral nozzles for optimal spraying in quenching, scrubbing, and evaporative cooling applications.

Spiral Spray Nozzles

The spray pattern of the spiral nozzle is formed by the fluid shearing along with the turns of the spiral, which produce multiple concentric cones. These cones form 2 to 3 bands of relatively coarse droplets, surrounded by wider bands of relatively fine droplets.

Spiral Full Cone

  • Larger coarse droplets are formed on the outer perimeter
  • Smaller droplets formed inside the cone

Spiral Hollow Cone

  • Larger coarse droplets are formed on the outer perimeter.
Examples of Why You Would Choose This Spray Pattern Over Others
  • If you are looking for gas cooling or want the liquid to react with a process for smaller droplet size, the spiral full cone nozzle gives you outstanding results.

  • If wind resistance and heat removal are a concern, the larger droplets produced by the spiral will give you outstanding results.
