BETE Spillback Nozzles - Fine Atomization Without Compressed Air

Unlike traditional hollow cone nozzles, BETE spillback nozzles are equipped with two connections and require no compressed air reducing operating costs. Spillback nozzles ensure uniform droplet size over the entire controlled flow range without changing the pump pressure to optimize processes for gas cooling and conditioning applications.

BETE can design and fabricate spray lances with a spillback nozzle for optimal nozzle placement. Our spillback nozzles and lances are made in the USA, with quick delivery for replacement nozzles.

Hollow Cone Spray Nozzles

A hollow cone nozzle sprays fluids in a ring-like pattern around a given radius. Hollow cone nozzles produce a good interface between air and the surface of the droplets.

There are 2 types of hollow cone nozzle designs.

Image

Axial

  • Spray exits on the same axis it enters
  • Internal channels or vanes causes the liquid to spin, and the centrifugal force exerted upon the geometry of the exit creates the spray pattern
  • Spray is concentrated on outer edges
  • Smaller droplets than full cone
Image

Tangential (Right Angle)

  • Spray exits 90° from the entry axis
  • Internal geometry creates the spray pattern by the liquid swirling around the body cavity before exiting the orifice
  • Spray is concentrated on outer edges
  • Smaller droplets than full cone
Examples of Why You Would Choose This Spray Pattern Over Others
  • In gas cooling applications, a small droplet size is desired,and a full cone nozzle may not be small enough.

  • Tangential hollow cone nozzles are perfect for low clearances when a pattern needs to be directed 90° from the inlet.
