Available now from Tecpro Australia , ultrasonic air atomising spray nozzles are air driven acoustic oscillators which atomise liquids into ultra fine droplets by passing them through a field of high frequency sound waves.
Liquid atomisation takes place through a two step process. Firstly the liquid must be ejected through a number of smaller orifices into the spray nozzle outlet orifice. Here, a central high velocity air stream produces the first liquid breakup through a shearing action.
Secondly, the air stream carrying the droplets impacts onto a resonator placed in front of the spray nozzle outlet orifice, generating a field of high frequency sound waves. As the droplets fly through this sound wave field they are broken into ultra fine droplets, which are then carried downstream by the air bypassing the resonator to come out as a soft, low speed 'fog'.
The key advantages of ultrasonic air atomising spray nozzles from Tecpro Australia include:
- infinite turndown ratio
- no dribble as even the finest drop is atomised
- self cleaning as sound waves keep the tip clean
- extremely large orifice that will not clog
- will produce consistent levels of droplet size over a wide flow range.
Ultrasonic air atomising spray nozzles are ideal for:
burning fuel, oil, and tar
- evaporative cooling or conditioning of hot gases
- dust suppression
