180 kHz Precision Ultrasonic Atomizing Nozzle
The 180kHz precision ultrasonic nozzle from Sono-Tek is the next generation advancement in precision ultrasonic coating technology. Designed to provide uniform thin film coatings onto substrates with highly complex geometries without overspray or webbing, the 180kHz ultrasonic nozzle is ideal for any spray application requiring very thin film coatings of solutions or nanosuspensions. It can easily be incoporated into Sono-Tek’s programmable XYZ coating systems, spray dryers, or other custom spray enclosures for uniform, micron sized thin film coatings.
180 kHz Nozzle benefits:
- 13μ median drop size provides excellent penetration to
complex substrates with intricate geometries
- Narrow drop size distribution maximizes uniformity
- Minimal overspray (minimal waste)
- Controllable drop size creates optimal coating morphology
- Very uniform and repeatable coatings
- Minimal servicing and downtime
- Self-cleaning ultrasonic nozzle prevents clogging
- Low velocity atomized spray produces reliable, consistent results
- Several liquid delivery options available with a wide range of delivery rates from 0.3 – 9 ml/min
The 180kHz ultrasonic nozzle atomizes liquid using high-frequency sound vibrations (at 180kHz) caused by exciting piezoelectric transducers inside of the nozzle body. An electrical signal fed into two electrodes situated between the piezoelectric transducers forming continuous vibrations down the nozzle’s titanium horn, creating a uniform spray of atomized droplets as the liquid emerges onto the atomizing surface. Featuring Titanium and stainless steel construction, Sono-Tek ultrasonic nozzles are durable and resistant to chemical attack. The comparatively large liquid feed orifice and ultrasonic vibration of the nozzle make it a virtually non-clogging device.
Nozzle Tip Geometry
The atomizing nozzle surface shape is conical or focused. The conical style nozzle creates a cone shaped spray pattern resulting from the conically shaped atomizing surface. The focused style nozzle is usually recommended for use in applications where flow rates are very low and narrow spray patterns are needed.) The focused tip is used when the nozzle is configured with our air shaping systems.
Air Shaping Systems
The 180kHz can be configured with either AccuMist or MicroMist air shaping systems. Both AccuMist and MicroMist systems employ low-velocity air (typically 1 psi) to direct and shape the spray into tight spray patterns for precise control of the spray to target areas.
