What Is Ultrasonic?

Ultrasonic Technology

 

Ultrasonic nozzles use very high frequency vibration instead of high pressure or compressed air to produce extremely small and uniform droplets. Capillary waves are produced on the surface of a liquid on a vibrating surface. During atomization, capillary waves are transformed by increasing the amplitude until the peak of the wave forms droplets. The wavelength, and subsequently the droplet size, are determined by vibration frequency. High vibration frequency generates fine droplets, and low vibration frequency generates coarse droplets.

The patented AccuJet® Ultrasonic Nozzle is designed to optimize spray coverage by atomizing fluids using ultrasonic vibration. The unpressurized, low-velocity spray gently settles on a target’s surface. This is unlike other types of nozzles that use high liquid pressure or compressed air in combination with liquid pressure to achieve atomization and also results in high velocity sprays which bounce off the target. With liquid flow rates between 0.04 and 15 ml/min, sprays can be customized and shaped to meet your process requirements.
