Overview of the superior ultrasonic nozzle spray coating technology

Ultrasonic spray nozzle systems have replaced pressure nozzles in a wide range of industrial and R&D applications.

For substrate coatings, moisturizing, thin film coatings, spray drying, web coating, fine line spraying, and many other industrial and R&D applications, Sono-Tek ultrasonic nozzles yield results far superior to other techniques.

Contrary to typical pressure nozzles the ultrasonic nozzles have the technological advantage of being more precise, more controllable and more environmentally friendly.

They deliver a soft spray, which reduces over spraying considerably which not only reduces atmospheric contamination but also saves money.

Benefits from ultrasonic atomizing coating systems

  • Compatible with almost any liquid
  • Spray patterns are easily shaped for precise coating applications
  • Highly controllable spray produces reliable, consistent results
  • Non-clogging
  • No moving parts to wear out
  • Corrosion-resistant titanium and stainless steel construction
  • Ultra-low flow rate capabilities
  • Intermittent or continuous operation
  • Material consumption reduced by up to 80%
  • Reduced wasteful overspray and atmospheric contamination
  • Reduced waste disposal
  • Reduced servicing and downtime

Over 500 different ultrasonic nozzle configurations

The soft spray produced often requires further shaping in order to meet the needs of an application, particularly where high precision of uniform deposition is required. Over 500 different ultrasonic nozzle configurations are available from Sono-Tek. To determine what system will best meet your needs, please contact Boel Nordic.
