Full cone nozzles - Air atomising design
These nozzles use a secondary fluid or gas to break up the primary spraying fluid into an exceptionally fine spray (atomisation). The secondary fluid is usually air, but can be any gas, but the term air atomising is used for all.
Air atomising nozzles can be used to produce evenly distributed, finely atomised full cone sprays in a range of spray angles.
One advantage of these over other types of full cone nozzle is that they can form a full cone pattern with very low flow rates. With spirals and whirl chamber designs the energy required to break up the fluid flow into a full cone pattern comes directly from the fluid being sprayed. This means that there is a natural restriction in minimum flow rates. With air atomisation a secondary source of energy is introduced in the form of pressurised gas. This is used to break up the fluid into a spray pattern. As such, atomisation and spray patterns can be maintained with much lower fluid flows from this type of nozzle.
BETE produce three variants of air atomising full cone nozzles. The internal mix XApr nozzle, which is suitable for non-viscous fluids, an external mix XAer which can cope with more viscous liquids, and the XAsr which is a narrow spray angle full cone nozzle. The Spiral Air high flow rate air atomiser also produces a full cone pattern. Full details on each product can be found by clicking on the product boxes below.
