Misting Nozzles, Behind the Fog, Key Elements To A Good Quality Mist

Misting Nozzles, water evaporation with a purpose.

Nozzle spray, the mist you are looking for. The nozzle with the right spray pattern and distance needed. The nozzle that evaporates, cools and humidifies in the desired spot.

Small orifice nozzles supply a fine mist that evaporates quickly. Mist direction and control is predictable. They spray where you want within a short distance, 3 to 5 feet. Spray pattern is narrow and focused for good directional control.

Small orifice nozzles, 0.08mm, 0.10mm and 0.15mm, provide the smallest water droplets. The smaller the droplets are the quicker the evaporation.

The right size mist plume with a small droplets are the keys to a successful misting solution.

Nozzle options also enhance mist production. Ball check valve for drip prevention and a internal filter which cleans the water entering the nozzle. These options help provide a quality mist and trouble free operation.

Adjusting system water pressure plays a large role in giving you the right mist plume size and distance needed.

How fine is the mist.

Most misting nozzle water droplets fall in the range of 25 to 75 micros. Droplet size also depends on nozzle orifice size and water pressure delivered to the nozzle. The higher the pressure the smaller the particle size. The smaller orifice nozzles tend to have a finer mist, smaller water particles.

Can nozzles be used at home with city water?

Generally not, the nozzle on this web site are high pressure nozzle with spring check valves that do not operate at city water pressure.

However with some modifiations they will work.

If you remove the ball from the spring check the water will get to the orifice. You have elimiated the check valve feature of the nozzle so it will drip a little on the OFF cycle.

Also, small orifice nozzles typically will not work at city water pressures. The orifice is to small. This is the 0.08mm and 0.10mm nozzles. The 0.15mm start to work pretty well at city water pressure. 0.20mm and up generally work good.

Can you do home humidification with these nozzle?

Not really, the mist is fine but not fine enough to evaporate before hitting the floor. I have got it to work in the furnace room where the temperature is high and relative humidity low is but not with any workable consisitantly.

You can't get the mist fine enough at city water pressures to evaporate quick enough without getting the floor wet. It takes high pressure to produce a fine mist. Also, as soon as you start to get the relative humidity up in the space it then starts to take longer for the mist to evaporate.

If you had the space in a basement with a floor drain and didn't mind get the floor wet it would work well. Much of the mist does evaporate before hitting the floor. Waist water would not be real high. There is very little water coming through these nozzles.

Are there good nozzles and bad nozzles?

Yes, But there is not really a good design compared to a bad design. More a good manufacturing cycle compared to a bad manufacturing cycle. Or I could also say, a good process to make quality nozzles. compared to a poor process that makes a poor mist with a higher failure rate. Nozzles do have a failure rate out of the factory averaging 2%. Many can be fixed by adjusting the head. Turn the head on tighter typically, sometimes looser. Or take apart and put back together adjusting head tightness.

Do Nozzles Fail?

Generally not as long as you are providing clean filtered water to them. They can become scaled however, on the tip with calcium and other elements that can eventually impede the mist flow. This scale can be removed with a de-scaler (viniger).

Are there different sizes of high pressure misting nozzles?

Yes, they range in the amount of water output. Water output is low. because we are talking about mist or fog. The best way to look at it in the USA is in gallons per hour. The output will change with the different water pressures but not that much. A 70% change in water pressure (300 - 1000 psi) may only change the water/mist output about 30%. With that knowledge a baseline can be formed for each nozzle.

The smallest misting nozzle puts out about 1/2 gallon per hour. The largest output is about 5 gallons per hour.

What determines the output? Is it orifice size?

Yes, however there is another basic factor in nozzle design that aids output. The angle of the spray or mist pattern. Generally the higher the output the wider the spray angle. Small capacity nozzles have a spray angle of around 30 degrees. High capacity nozzles may have a angle of 70 degrees. Some of the smaller nozzles don't have design spray angle. Essentially they try to output as little mist as possible which generally is about a 30 degree spray pattern.

The 3 nozzle heads above show differances in orifice material. The orifices on each end are ceramic with a nickel plated brass material. The orifice in the middle is an all stainless steel head and orifice.

0.10mm Nozzle Spray Pattern at 500 psi

Both pictures, above and below, the mist is pointing straight down. The mist is slightly heavier than air so the mist is also falling down. If the nozzle was pointed up it would disperse in a wide pattern much different than seen here.

0.40mm Nozzle Spray Pattern at 500 psi

0.10mm nozzle disperses about 4 lbs. of water per hour (1/2 of a gallon) where the 0.40mm nozzle disperses about 20 lbs. per hour (2.5 gallons). Spray pattern gets wider with larger orifice. Spreading out the mist keeps droplet size down and evaporation rate high.

Picture below is the same nozzles above but side by side.
