Product Overview: No Drip External Mix Atomizing Spray Nozzles

EXAIR’s Atomizing Nozzles are commonly used to clean, cool or coat parts as well as humidification or to control dust. They are constructed of 303ss, providing superior corrosion resistance and are able to withstand temperature up to 400°F (204°C).

The Atomizing Nozzles are separated into 3 categories – Internal Mix, External Mix and Siphon Fed.

For today’s topic, we will focus on the No Drip External Mix Atomizing Nozzles.

No Drip External Mix Atomizing Nozzles provide the highest flow rates

The External Mix Atomizing Spray Nozzles require a pressurized liquid source and compressed air source to produce a mist of atomized liquid. With the liquid and air being mixed external to the nozzle, they are able to handle higher viscosity fluids above 300 cP.

Our patented No Drip feature positively stops the liquid flow when the supply air pressure drops below 20 PSIG for 1/8″ NPT Nozzles or 30 PSIG for the 1/4″ or 1/2″ NPT. By incorporating this feature into the design, it eliminates the need for any additional valves or supply lines.

Available flow rates range from 2 GPH for our Model # EF9010SS 1/8″ No Drip External Mix Narrow Angle Flat Fan Pattern and up to 303 GPH for the Model # EF6010SS 1/2″ No Drip External Mix Narrow Angle Flat Fan Pattern.

When making a selection, there are 5 common considerations to take into account:

  1. How much liquid flow do I need?
  2. Is the liquid pressurized?
  3. What is the viscosity of the liquid?
  4. How wide of an area needs to be treated?
  5. What type of spray pattern fits the application?

If you have an application requiring a fine mist of atomized liquid or if you’d like to discuss another product or application, contact one of our application engineers for assistance.

Internal Mix Atomizing Spray Nozzle Used In Feed Additive Process

Last week I took a call from an agricultural customer looking to replace the spray nozzle used in their feed additive process. The soy oil/beeswax solution they are applying to the feed, is slightly viscous (close to 100 cP) which seems to be clogging the tight clearances inside the current nozzle, resulting in varying flow rates and an erratic spray pattern. They had tried to contact the current manufacturer several times for a solution but were unhappy with the lack of assistance they were receiving, not to mention the long lead times of 6-8 weeks for a replacement.

After further discussion, they confirmed they weren’t as concerned with the flow rate or spray pattern, as they were with the nozzle potentially getting clogged.  They were able to obtain some internal dimensions of the existing nozzle and after further review, I recommended they use our Model # AF1030SS Internal Mix Flat Pattern Atomizing Nozzle as a replacement. This nozzle has larger inside diameters which would reduce the potential for clogging. Our Internal Mix Atomizing Nozzles mix the liquid and air inside the air cap and produce the finest atomization. The flow rate can be changed by adjusting the control valve on the nozzle and/or by adjusting the liquid pressure. Internal Mix nozzles are capable of handling fluids up to 300 Centipoise. All of our Atomizing Nozzles are In STOCK, so delivery is never an issue.

Model AF1030SS Internal Mix Flat Fan Pattern Atomizing Nozzle

When considering an Atomizing Nozzle for an application, there are some general parameters that can be helpful in making the best selection.

  1. Do you have a pressurized liquid source?
  2. What is the fluid viscosity?
  3. What spray pattern best fits the process?
  4. How much flow (GPH/LPH) do I need?

If you have an application requiring a fine mist of atomized liquid spray, please contact an application engineer for assistance.

EXAIR No-Drip Atomizing Spray Nozzles Recognized By Plant Engineering

AW2030ss559
EXAIR’s patented Model AW2030SS No-Drip Atomizing Spray Nozzle

If you follow our blog, Twitter, or Facebook pages, you may have seen us mentioning recent nominations for Plant Engineering Product of the Year Awards.  2015 will mark the 28th anniversary for this award, in which Plant Engineering readers select the most outstanding new products that help them do their jobs smarter, safer, more efficiently, and more productively.

Considering the pre-qualifiers for such an award, it makes sense that EXAIR products would show up, and show up repeatedly.  This year our No-Drip Atomizing Spray Nozzles have been nominated as a finalist in the Fluid Handling category.

Products in this field are recognized to present improvement potential, allowing users to create a more innovative process.  EXAIR No-Drip Atomizing Spray Nozzles do so by providing effortless integration of controlled liquid spraying.

Compressed air and pressurized (or non-pressurized) liquid are plumbed to the nozzle.  When compressed air is flowing, liquid will flow as well.  When compressed air flow stops, liquid flow stops.  Immediately.

For an end user of this product, this means that a precise volume of a specific liquid can be sprayed in a given time (duty cycle), with complete control before, during, and after nozzle activation.

The key to adding this innovation rests in the proprietary, patented (#9,156,045) design  of EXAIR’s No-Drip Atomizing Spray Nozzles.  Our engineers have worked tirelessly to create a stand-alone nozzle capable of controlling liquid flow without requiring a liquid control solenoid.

The viability of these nozzles has been recognized by Plant Engineering as an innovative new product in 2015.  If you agree and would like to cast a vote for EXAIR, please click here.

We thank you for your readership and, hopefully, for your support in this competition.
