What is Atomization?

Atomization refers to the process of breaking up liquids into droplets. Fine Air Atomizing nozzle droplet sizes are measured in microns. Common home atomizers you may be familiar with include shower heads, perfume sprays, garden hoses, and deodorant or hair sprays. 

What is Air Atomizing Nozzle and How its different from atomizing nozzles?

In direct pressure nozzles, the fluid is broken up (atomized) into droplets by either impact on a surface or by the swrilling motion caused by passing the liquid through a shaped orifice. In both cases the energy required for the atomization comes from the potential energy of the fluid itself. Essentially the energy available for atomization is a function of fluid pressure.

In air atomising nozzles pressurized air (or other gas) is used to impact upon the fluid being sprayed. The impact of the gas causes the fluid to break apart into a fine spray. This means that the energy required for atomisation is no longer dependent on fluid pressure because of which very fine sprays can be produced at low fluid pressures. The allows for very fine, low volume sprays to be delivered.

 Air Atomising Nozzles have many unique spray properties and specification which helps the designers to use in wide range of spraying applications.

What are the types of Atomisers avaialble?

Spray atomization involves creating a condition of high relative velocity between the liquid to be atomized and the surrounding air or gas. Typical atomizer nozzle types include:

  • Electrostatic
  • Impinging jet
  • Windmill
  • Whistle
  • Ultrasonic
  • Twin fluid. Twin-fluid atomizers include all nozzle types, and may involve one of the processes below:

Internal Mix – The gas and liquid are mixed within the body of the nozzle. It forms the finest atomization, which exits through one orifice. There is a direct relationship between the liquid and the air; any change in the air pressure affects the liquid flow. The full cone, hollow cone and flat spray patterns can be achieved using the internal mix method.

External Mix – The gas and liquid are mixed externally; this offers better control since there is no connection between the gas and liquid inlet lines. Viscous liquids can be sprayed using External mixtures. however, the atomization is not as fine as in the internal mix. Both full cone and flat spray patterns are achievable.

What are the Air Atomizing nozzle Types available with Synergy Spray Systems?

Five types of Air Atomizing nozzles are designed and available with us

  • External Mixture Flat Fan 
  • Internal Mixture Siphon Flat Fan 
  • Internal Mixture defelected flat fan
  • Internal Mixture wide angle 
  • Internal Mixture Jet round
  • External Mixture Narrow round 
  • Paint Spray Atomizing Nozzle

External Mixture Flat Fan Air Atomizing Spray Nozzle

The air and liquid streams exit the nozzle independently and are combined and mixed outside of the nozzles. Because there is no connection between the air and liquid lines within the nozzles, the air and liquid flow rates can be controlled independently, allowing precise metering of the liquid. The atomization can be controlled by adjusting the air flow rate more air produces finer atomization. In most cases these set-up do not atomize as finely as Internal Mix Setups.

External Mix Set-up may be used with liquid having a viscosity.

All External mixing Air Atomizing spray nozzles can works above viscosity of 250 cP. External mix nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These nozzles are best where precise liquid flow is needed. we have air atomizing nozzle models which fits to 1/4 male connector (Nozzle has 1/4″ Female size) and made up of SS316 material.

Other materials available are brass, SS304 and Duplex steel or based on customer requirements.

Atomizing nozzles for viscous fluids and for applications that benefit from increased spray nozzle control. i.e control of pattern and droplet size independent of shape air or atomizing air and control air. Externally atomized with built-in pneumatic control valve.

Internal Mixture jet Air Atomizing Spray Nozzle

Internal mixing Air Atomizing spray nozzles – Liquid and air mixed together within nozzle and dispensed through a single orifice. A change in air flow will affect the liquid flow. This makes precise metering of the liquid more difficult than with an External Mix Set-up. Internal Mix set-up are able to produce the finest atomization, but they are generally not suitable for use with liquids which have a higher viscosity.

This Air atomizing nozzle flow like a jet spray nozzle pattern. This is not a straight jet spray nozzle pattern (where the jet stream with a spray angle of 0 degree) but a full cone shaped water flow.

All Internal mixing Air Atomizing spray nozzles can works up to viscosity of 250 cP. Internal mix nozzles are available in three patterns: narrow angle round pattern, wide angle round pattern and flat fan pattern. we have air atomizing nozzle models which fits to 1/4 male connector (Nozzle has 1/4″ Female size) and made up of SS316 material.

Other materials available are brass, SS304 and Duplex steel or based on customer requirements.
