Ultrasonic Spray Nozzles

Microspray works closely with Universities, R&D efforts and industry to provide solutions utilizing ultrasonic spray nozzles for a variety of cutting edge technologies as well as established industrial applications.  Ultrasonics nozzles (also referred to as an ultrasonic nebulizer) have been a preferred choice over conventional air spray applicators, dip coating processes and other coating methodologies for many of the unique features ultrasonic spray coating nozzles provide.  For example, an ultrasonic nozzle is an air-less systems, the ultrasonication of the spray nozzle makes it anti-clogging and the spray nozzle is constructed of highly durable materials such as titanium making it well suited for a variety of challenging environments and chemistries.

We at Microspray pride ourselves in taking great care in specifying the correct ultrasonic spray nozzle solution for your process.  Our experienced staff has decades of hands-on experience working closing with academia, R&D facilities and industry.  We often offer custom solutions that meet the needs of up and coming cutting edge technologies, such as nanotechnology, hydrogen fuel cells, antimicrobial coatings, medical related coatings, spray pyrolysis, etc.   We often provide for established industries ultrasonic spray technologies that result in a reduction of waste, improved transfer efficiencies and higher coating uniformity.

Please feel free to send us an e-mail or call for your most challenging ultrasonic nozzle applications.  We have hands on experience with thousands of different ultrasonic nozzle applications.  We have a reputation for “out-of-box” thinking and helping customers with their unique academic and industrial applications.

How Ultrasonics Spray Nozzles Work

Ultrasonic spray nozzles are constructed to vibrate longitudinally at high frequency by means of piezoelectric transducers.  This longitudinal up and down motion creates standing waves in a thin film of applied liquid on the ultrasonic nozzle tip, in which the amplitude of these waves can be controlled by the power generator.  These standing liquid waves can be extended upwards off the ultrasonic nozzle tip to the point they separate into evenly sized droplets with little to no kinetic energy (see video).  Secondary shaping gas or ambient air can be used to easily entrain droplets to the desired shape and velocity if needed. A variety of ultrasonic nozzles are offered that help determine droplet size, liquid flow rate and spray patterns.


Some of the many benefits of ultrasonic nozzles:

    • High Transfer Efficiency – Reduces materials usage
    • Non clogging – Able to handle high-solid materials
    • Durability –  Titanium construction is resistant to many solvents and abrasion.
    • Highly uniform distribution of droplet sizes – Reduces coating imperfections.
    • Airless spray – Can easily control process and also ideal for vacuum environments!
