LIQUID ATOMIZING SPRAY NOZZLES – how they work and available options

EXAIR’s Liquid Atomizing Nozzles are some of the very few items that we make that do not use compressed air as the energy source. Instead, pressurized liquids provide the energy. Sometimes the nozzles will create an internal spinning liquid or the nozzle will cause the liquid to impact another surface. Each method , spinning or impacting, causes the liquid to lose its surface tension and atomize into small droplets. These nozzles can generate more liquid flow than our Air Atomizing Nozzles, which mix the liquid with air and produce the smallest droplet sizes. Depending on your liquid atomizing nozzle selection, you can spray anywhere from 0.48 gallons per minute, up to 17.64 gallons per minute.

This amount of liquid is typically used for cooling, rinsing, dust suppression and washing, but there are many other applications as well. These nozzles will work well with solution that have particulates in it, including slurries.

With a very small footprint, all stainless steel construction, and no moving parts, these are a great fit, for not only the easy to get to conveyors or containers, but also those hard to reach spots as well. Couple this with not needing air, and they are easy to plumb, and easy to use. They are made of 303 Stainless Steel and can accommodate temps up to 800°F.

Currently, we have 2 liquid nozzle types. One type is a FullStream Cone which comes in 1/4″, 3/8″ and 1/2″ NPT. The other type is a HollowStream Cone that comes in 1/4″ and 3/8″ NPT. With these nozzles, the fluid is supplied into the body creating a swirling action within the vortex chamber. This Vortex is what creates the cone pattern. Then the precision orifice of the nozzle breaks this surface tension, and it leaves the nozzle with a full circular pattern (FullSstream), or a hollow ring pattern (HollowStream).

With this information, we are now down to choosing the size we need. We offer performance tables, within our catalogue, or on the website, that will show you the following:

  1. Inlet Connection
  2. Nozzle Capacity
  3. Max Free Passage (Orifice size for particulate)
  4. Flow Rates in Gallons (or Litres) per minute bases on psi of liquid
  5. Spray width based upon the psi, and distance from the surface

Here is an example of the FullStream Cone Nozzles – 1/4″ NPT:

As you choose your Liquid Atomizing Nozzle, it all comes down to the type of spray you need and how much liquid you need to spray. Once you decide betwen FullStream or HollowStream Cone and you know the amount of liquid pressure you have (and can adjust too) and the amount of liquid you are wanting to spray, comes down to scouting the performance tables of the sizes we offer and selecting the perfect one for your application.

Engineered, Intelligent Compressed Air® Products: Save Air AND Get a Rebate!

This rebate example results in FREE air nozzles – read on to learn more!

Here at EXAIR we are continuously trying to share the basic facts that engineered air nozzles save compressed air. We then connect that with the amount of money that it saves, this is generally backed with formulas, this isn’t a new concept, we blog, tweet and even have easily accessed calculators for it. The final part that we like to share is that, on top of saving throughout the life of the nozzle, there are also many energy providers and municipalities that extend a rebate program as well! That means this lowers the ROI on implementing engineered nozzles into your system.

For instance, if your facility is located in Holland, Michigan, the Holland Board of Public Works wants to offer a rather simple rebate that requires the engineered nozzle and application be installed and submitted by December 31, 2022. The program is offering up to $100 per engineered nozzle installed on an open pipe or tube. (The incentive cannot exceed 100% of customer cost.) Not sure if you have open pipes in your facility? I’m sure you will hear them if you walk near the production lines where air is used. Or, better yet, get in touch with your production maintenance team and have them go throughout the facility and perform an open tube/pipe tagging event. Then report back and contact an Application Engineer here at EXAIR. We will all be able to help you with selecting the appropriately sized engineered nozzle to convert that open pipe/tube blowoff to an efficient and safe blowoff.

The Holland program is focused on open pipe/tube blowoffs while there are countless other programs out there which focus on replacing any blowoff with an engineered nozzle that also fits certain flow criteria for select pipe sizes. These programs can be searched by using the site Dsireusa.org This is a site that is maintained by NC State University and NC Clean Energy Technology. You can easily navigate to your state and scan the list for a rebate program which will then even take you to the application and stipulations for the selected incentive.

No matter where you are located in the world, you don’t have to use a rebate to save money by installing engineered nozzles. The savings and ROI all starts as soon as they are installed. The rebates available in various parts of the US are just ways to expedite the ROI. If you want to discuss any engineered nozzle application, contact an Application Engineer today.

Application Database: Agriculture.

EXAIR uses many different methods to connect with our customers.  We have our website, social media, blogs, publications etc.  We like to share solutions for some of the most common pneumatic problems in the industry.  EXAIR generated a large collection of application information where EXAIR products have solved problems and improved processes, and we placed them in a database.  We organized them by Application and by Industry.  In this blog, I will show you how to use our application database; specifically for agriculture.

The agricultural industry is an essential business for people around the world.  So, it is very important to reduce costs and improve processes.  EXAIR has engineered products that can help in these areas.  This can include spraying fungicide, conveying products, blowing compressed air, and monitoring pneumatic systems.  Compressed Air Systems are considered to be a fourth utility within industries because they use a large amount of energy.  Whether an air compressor uses electricity or fuel for portable units, it is important to use this system as efficiently as possible.  EXAIR has a library of different processes in which we already have improved in these areas safely and efficiently.  If you are part of the Agricultural industry, it can be beneficial for you to find the areas that we already improved.  It is a “been there, done that” solution that you can take an advantage of using. 

Here is how you can find this library.  First, you will have to sign into the EXAIR website.  Click HERE to log in.  Once you fill in the proper information, you can then retrieve a great number of resources about EXAIR products that we manufacture.   The Application database is located under the Resources drop-down tab (Reference photo below) and at Applications.

At the Application Search Library, we have over one thousand applications that we reference.  In the left selection pane, we organized them in alphabetical order under two categories, Application and Industry.

Scroll down in the Industry selection pane until you come to the sub-category: Agriculture.  If you do not find it, you can select the Expand button to open up more industries.  We have other applications as well that may relate to your specific process if you scroll up and down the list, like Food and Beverage as examples. 

Why is this important?  If you are a plant manager or owner, the value of the Application Database can help your current processes with pre-qualified results.  Within the Agriculture industry, simple solutions can be found to address those “nagging” issues that you see every day.  For crisis situations and shutdowns, EXAIR categorized these applications in a way to reference quickly and easily.  And since EXAIR has a high volume of stocked items, we can get the parts to you very fast so you can quickly be on your way to a solution.

Rugged, Stainless Steel Liquid Nozzles Available to Ship From Stock: The FullStream Cone Nozzles

New to EXAIR’s line of Liquid Atomizing Nozzles are the FullStream Liquid Only Atomizing Nozzles. This family of nozzles does not require any source of compressed air to operate, just a supply of pressurized liquid.

They produce droplets by spinning the liquid and breaking its surface tension through a precise orifice or by impacting the liquid onto the surface of the nozzle. Compared to EXAIR’s Air Atomizing Spray Nozzles, these nozzles generate more liquid volume and produce a coarser spray pattern. This higher liquid volume is beneficial for industrial applications including cleaning, cooling, rinsing, dust suppression, and washing. Constructed of Type 303 stainless steel, these durable and rugged nozzles are ideal for industrial applications. They’re available in three sizes: ¼ NPT, 3/8 NPT, and ½ NPT these nozzles can achieve flowrates ranging from 0.5 GPM to 17.64 GPM.

This style of nozzle is a good fit for general-purpose applications in industry and will commonly be used to spray inexpensive liquids such as water, rinse aids, or detergents. They’re also effective for spraying a variety of chemicals, pesticides, and herbicides.

Adjustments to the nozzle’s liquid flow rate can be achieved by regulating the liquid pressure supplied to the nozzles. As we increase the liquid pressure, the flow through the nozzle will increase. As the pressure increases, not only do we increase the overall liquid flow rate but also the size of the spray pattern. If a tight tolerance in liquid flowrate is needed, the Air Atomizing Nozzles will provide more precise control over the application of fluids.

The FullStream Cone Nozzles produce a full cone spray pattern and are among the most common style of spray nozzle available on the market today. They produce a uniform distribution of liquid in a cone shaped round pattern. Their tangential flow is vaneless, creating open internal features that are resistant to clogging for liquids with suspended particles.

The nozzles are manufactured out of Type 303 stainless steel for durable and rugged applications up to a maximum temperature of 800°F. With absolutely no moving parts, these nozzles are Built to Last. All sizes are available in stock to ship today with an order in by 2:00 EDT.
