Misting nozzles function in cooling by atomizing pressurized water into aerosol particles that “flash-evaporate”. The smaller the water droplets, the better the cooling. throw of mist nozzles can go up to 2 to 3 meters. Higher the pressure, fine mist is produced High Pressure Mist Nozzle with wide range of orifice from 0.10mm, 0.15mm, 0.20 mm, 0.30 mm, 0.40 mm, 0.50 mm, 0.60 mm These cleanable Anti-Drip nozzles provide long lasting performance for variety of applications with corrosive and higher viscosity liquids. Most common uses include mid/high pressure misting systems, mosquito/insect control systems, odor control and special effects. Misting System Nozzles Characteristics: Cleanable Stainless Steel Orifice Fine Atomization 3/16 Thread Stainless Steel Body Built in Anti-Drip Feature High Pressure springs need 250 psi to open / Low pressure springs need 65 psi to open 100 psi is recommended. Specify what springs you need. Note: Low pressure springs performance may vary. These nozzles will work with no springs as well. The .012″/.30mm nozzle is the medium sized standard nozzle orifice. At 1,000 psi, the mean diameter of the droplets from this size orifice are 13.1μ with droplets ranging from 1.6μ to 39.1μ with a spray diameter of between 65 degrees and 75 degrees. The .012″/.30mm misting nozzle is ideal for applications requiring moderate flow with small droplet size. It has a similar performance to the .008″/.20mm orifice nozzle with an increased flow rate. It is most commonly used for outdoor cooling odor/dust control applications. This nozzle can be used with any pressures.100 psi or more is better.
