External Mixture Flat Fan Air Atomizing Spray Nozzle

Description

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.

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.

Properties:

1. External Mixing: Liquid and air meet outside the nozzle, ensuring no internal mixing or clogging, especially when working with viscous or particle-laden liquids.
2. Precise Control: Separate control over air and liquid flow rates allows for fine adjustments to droplet size and spray pattern.
3. Customizable Spray Patterns: Available in multiple patterns, such as flat fan, round, or full cone, depending on application needs.
4. Low Operating Pressure: Functions efficiently at relatively low liquid and air pressures.

Common Applications:

• High Viscous Liquid Spray with Air
• Coating Processes: Applying uniform coatings in industries like food processing, pharmaceuticals, and manufacturing.
• Cooling and Humidification: Used in evaporative cooling and maintaining humidity in controlled environments.
• Dust Suppression: Ideal for reducing airborne particulates in industrial and mining applications.
• Spray Drying: Employed in drying systems where fine mist formation is critical.

Advantages:

• Non-clogging design due to external mixing.
• Flexibility in handling a wide range of fluids, including those with high viscosity or particulates.
• Greater control over atomization, allowing for efficient use of liquids and air.
