Internal Mix Atomizing Spray Nozzle Used In Feed Additive Process

Published on by exaircorpLeave a comment

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.

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.

Atomizing Nozzles Create Fog for Wet Room Testing

Published on by Leave a comment

Recently, I was working with a customer that has purchased several of the EXAIR Atomizing Spray Nozzles, specifically the model Aw5020SS.  The customer had another project coming up and needed two more nozzles. I inquired about the application and we discussed at length the way the nozzles are being used.

When a concrete road is being poured, several sample forms are poured during the process. The local Department of Transportation takes the samples and cures them in a wet room for 30 days, and then performs tensile testing, to confirm the concrete meets the strength requirements.  The wet room must be kept at 23°C (73.4°F) and 100% Humidity during this time frame.  The EXAIR model AW5020SS Atomizing Nozzles are used to provide the moisture that ensures the room humidity conditions are met and maintained.  Because the droplets are very fine, the effect of a fog is achieved, with the water droplets suspended in the air, keeping the humidity at 100%.

Atomizing spray nozzles are capable of producing very fine droplet sizes.  A typical rain drop is 6000 microns in diameter, standard liquid nozzles produce droplets ranging from 300-4000 microns.  The EXAIR Atomizing Nozzles produce droplets from 20-100 microns!

Droplet  sizes can be adjusted by varying either the liquid pressure or air pressure. Increasing the air or decreasing the liquid pressure will generally produce a smaller droplet size.

EXAIR manufactures (3) types of Atomizing Nozzles – Internal Mix, External Mix, and Siphon Fed, in both 1/4 NPT and 1/2 NPT sizes. Maximum liquid viscosity is 800 cP. Flow rates range from 0.6 GPH up to 303 GPH, so we’ll be able to find one that meets your flow requirements.

To discuss your application and how an EXAIR Atomizing Nozzle can benefit your process, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

EXAIR No-Drip Atomizing Spray Nozzles Recognized By Plant Engineering

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.

The Bigger, The Better

Published on by exaircorpLeave a comment

One of my favorite hobbies over the summer months is going camping with my family. I grew up camping with my grandparents, brother and 2 cousins. My grandparents did have a camper but the majority of the time, the 4 of us kids, camped behind the trailer in tents. My wife on the other hand was a “newbie” to the whole camping scene so when we decided to begin this adventure we purchased a low-cost, lightweight hybrid style camper so she could have all the amenities to keep her comfortable – a bed, A/C, toilet and TV.

This year we were planning on going on an early vacation in May so I wanted to get the camper out of storage and prepare it before we left so when we got back we could start our weekend camping trips right away. I headed over to the storage lot only to find a tree branch had fallen through the roof! Needless to say, I was not a “happy camper” (pun intended). Not only that but it appeared it happened some time ago as the ceiling and certain parts of the floor were getting soft from rain. I immediately called my insurance company to file a claim and dropped the unit off at my local RV shop.

Uuummmm – I need to speak to the “Branch Manager”

After about a week, I received the call from the RV shop advising of the repair costs which were about $3,000 higher than the actual value of the trailer. The insurance reviewed this information and determined the unit as a total loss and would be issuing us a check for the market value of the unit. We were somewhat bummed because we really liked our little camper and the memories we shared. Our oldest son learned to ride his bike w/o training wheels and he caught his first fish while camping in that trailer. Now that my wife is on board with camping and with the extra $ in our pocket, it’s time to shop for a bigger, new camper – I am thinking 5th wheel! This also means a truck upgrade to something bigger, at least a 3/4 ton, something I am sure will make my wife happy.

Keeping with the bigger theme, here at EXAIR we recently released our NEW 1/2″ Atomizing Nozzles. The larger size allows for higher flow rates and larger coverage areas.

Model EF5010SS
NEW Model # EF5010SS – 1/2″ NPT External Mix Narrow Angle Flat Fan Pattern Atomizing Nozzle

We offer the following options:

Internal Mix Narrow Angle Round Pattern – Flows up to 231 GPH, require pressurized liquid and air.

Internal Mix Wide Angle Round Pattern – Ideal for covering a large area, adjustable to a fine mist or heavy spray.

Internal Mix Flat Fan Pattern – Perfect for efficient output of costly liquids.

Internal Mix 360° Hollow Circular Pattern – Provides 360° even flow in all directions.

External Mix Narrow Angle Flat Fan Pattern – Able to handle thicker fluids than internal mix and providing independent air and liquid control.

Siphon Fed Round Pattern – For non-pressured liquid applications, up to 24″ of suction lift.

All of the above are also available with our No Drip feature to stop the liquid flow after the air supply has been turned off.
