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:
- Inlet Connection
- Nozzle Capacity
- Max Free Passage (Orifice size for particulate)
- Flow Rates in Gallons (or Litres) per minute bases on psi of liquid
- 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.
