Ultrasonic nozzles – precision and efficiency, perfected
Ultrasonic nozzles use high-frequency vibrations to atomise liquids exceptionally finely and uniformly. This technology produces droplet sizes in the micrometre range – ideal for applications that demand precision, efficiency and consistent quality.
Fine atomisation for maximum precision
- Extremely fine droplet sizes (typically 10–150 µm)
- Uniform spray pattern distribution
- Ideal for homogeneous coatings and exact dosing
High energy efficiency
- Lower energy demand than pressure or two-fluid nozzles
- No compressed air required (depending on design)
- Reduced material loss through precise liquid metering
Improved process control
- Exact regulation of flow rate and droplet size
- Very consistent spray pattern — independent of pressure fluctuations
- Automated adaptation to changing process conditions
Premix nozzles & pressure atomisers
Premix nozzles – operating-media-optimised with comparable results
With premix nozzles, the medium to be atomised and the atomising medium are pre-mixed and pre-atomised inside the nozzle – ideal when compressed-air availability is low and for moderately solids-laden media.
- Ideal for contaminated media and retrofits of existing plants
- Low energy demand
- Little to no abrasion from solids (depending on design)
Pressure atomisers – reliable atomisation of clean media
At higher inlet pressure, the medium is atomised through a geometric constriction – entirely without an atomising medium.
Versatile fields of use
Ultrasonic nozzles are used across many sectors:
- Medical & pharmaInhalation systems, coatings.
- Chemical industryPrecise reagent dosing.
- Food technologyFine flavouring, glaze application.
- Surface coatingUniform film formation with minimal material use.
- Exhaust & environmentalCooling and humidification of gas streams.
Flashback-safe exhaust combustion
Many chemical and pharmaceutical processes generate gaseous by-products with fluctuating composition and volume. The proven method for treating these exhaust streams is combustion in adiabatic chambers with downstream heat recovery.
Because these gases often contain oxygen or are otherwise highly explosive, detonation and deflagration arresters are mandatory. The combination of static and dynamic flashback protection is particularly effective — the latter ensures the gas flow velocity always remains above flashback velocity, often by adding inert gases such as nitrogen.
PAVIK has developed a dedicated injection system that delivers dynamic flashback safety without adding auxiliary media.
Atomisation with pure oxygen
Instead of compressed air or steam, PAVIK uses pure oxygen for fuel atomisation. This brings numerous benefits:
- Higher efficiencyThrough optimised fuel atomisation.
- Greater outputFor the same fuel input.
- More flexibilityEven with difficult or low-grade fuels.
- Less energyNo auxiliary media required.
- Stable processesEven under variable operating conditions.
Low maintenance, long service life
Less wear at low operating pressures, robust construction for long service intervals, and minimised cleaning and maintenance costs — ultrasonic nozzles combine technical precision with economic advantages and open up versatile applications in industry, medical technology and environmental engineering.
