Sonicom ultrasonic nozzles

J D UltraSonics Ltd - suppliers of ultrasonic nozzles & atomisers

ultrasonic nozzlesJ D UltraSonics Limited are leading European Agents for the unique range of sonicom™ ultrasonic humidifiers, atomising and fogging nozzles. Based in the UK, our range of air assisted spray nozzles and atomisers produce micro fine droplets to give a true dry fog for humidity control, dust suppression and evaporative gas cooling. We supply clients throughout the world from many diverse industries who require reliable liquid atomisation economically and effectively.

"sonicom atomisers shatter liquids with sound waves"

Sonicom nozzles are activated by pressurised gas...... either compressed air or steam. Air passes through the nozzle's inner bore through a convergent/divergent section at high velocities and expands into a resonaultrasonic nozzlestor 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 shock wave is vigorously sheared into fine droplets by the acoustic field. Air bypassing the resonator carries the atomised droplets downstream in a soft plume shaped spray. The droplets have low mass and low forward velocity with low impingement characteristics. Fine atomisation ensures uniform distribution of the liquid with minimum over spray and waste.

Sonicom atomising nozzles operate at very low liquid pressures and have large orifices. The large orifices and low pressure virtually eliminate orifice wear and prevent deterioration of the quality of atomisation while greatly extending useful nozzle life.

The great advantage of sonicom atomising nozzles is their ability to provide a consistent quality of atomisation over a wide flow range. TuNozzle Close-Uprndown ratios of 50 to 1 are possible: by varying air pressure, atomisation quality can be varied from coarse (50 to 300 microns) to an ultra-fine fog (1 to 10 microns).

Designed and developed by J D Ultrasonics, the sonicom non-drip water valve assembly ensures optimum performance from the standard range of sonicom nozzles with added advantages:-

  • nozzle begins to atomise instantly the start signal is received
  • valve ensures nozzle does not drip when switched off
  • purge air cleans the nozzle at the beginning and end of every cycle
  • mounting is simple due to flat body design and M5 clear through holes in the body
  • swivel mounting bracket allows nozzle to spray directionally
  • controls are simple as additional timers and sequencing of air and water is not required


The water valve body is manufactured from stainless steel with stainless springs and spindle. All internal seals are viton to withstand temperatures of 120°C (250°F). Fittings can also be supplied to complement the body material and match temperature requirement.
