By using BETE as a single supplier, you can be sure your lance will be correct the first time, every time.
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. When you require a small droplet size with capacity, these nozzles fill the bill. Tangential hollow cone nozzles are perfect for low clearances when a pattern needs to be directed 90° from the inlet.
Tangential Whirl: Tangential hollow cone nozzles utilize a supply of liquid perpendicular to the direction of spray. Flow enters a swirl chamber without the use of internal components — allowing for maximum clog resistance.
Whirl nozzles: Whirl hollow cone nozzles supply axially to the spray. The inlet of the nozzle and direction of the spray are inline. Flow enters the nozzle and is directed by channels or vanes to swirl along the axis of the nozzle. The emitting spray is atomized in a hollow cone pattern.
Spiral Nozzles: Spiral hollow cone nozzles also supply axially to the spray. The inlet of the nozzle and direction of the spray are inline. Flow enters the nozzle and is directed by and external spiral. Flow shears off the edges of the spiral, atomizing the fluid.
Depending on the nozzle series, a Hollow Cone can operate as low as 5 psi and as high as the material allows. Plastic nozzles are limited in pressure to 75 psi to a couple 100 psi. Alloy nozzles can operate at a couple 1000 psi.

In gas cooling applications, a small droplet size is desired and a full cone nozzle may not be small enough.
