What are Ultrasonic Fogging Nozzles
Ultrasonic fogging nozzles are twin fluid type spray nozzles, usually using compressed air and water to create a finely atomised water droplet, typically this nozzle range produces droplets from 3 to 10 micron. This ultra-fine droplet is created through its unique nozzle design compressed air passes through the nozzle at high velocities and expands into a resonator cavity where it is reflected back to complement and amplify the primary shock wave. The result is an intensified field of sonic energy focused between the nozzle body and the resonator cap.
Any liquid capable of being pumped into the shockwave is vigorously sheered into fine droplets by the acoustic field. The droplets have low mass and low forward velocity with low impingement characteristics. Fine atomisation ensures uniform distribution of the liquid with minimum of overspray and waste.
The Ultrasonic nozzle range has the ability to provide a consistent quality of atomisation over a wide range of flow rates. Turn down ratios of 50 to 1 is possible.
For optimal control of your ultrasonic spray system the use of a Sealpump control package helps conserve liquid usage and reduces waste by monitoring and automatically adjusting spray coverage, flow rate, droplet size, liquid and air pressures
