Description
The Dry Fog Humidifier Nozzle System is a high-efficiency spray humidification solution designed to create a stable and uniform humidity environment without condensation or surface wetting.
It works on the principle of compressed air + water two-fluid atomization, where high-velocity air breaks water into microscopic droplets. These droplets remain suspended in the air, forming a dry fog that quickly evaporates and increases relative humidity.
Unlike conventional humidifiers, this system produces ultra-fine mist that does not settle as liquid, ensuring safe operation in sensitive production environments.
The system is widely used where strict humidity control, static elimination, dust suppression, and cooling efficiency are required.

FAQ
1. What is the operating principle of a Dry Fog Humidifier Nozzle?
It operates on a two-fluid atomization principle where compressed air shears pressurized water into micron-sized droplets through high-velocity mixing and turbulence at the nozzle tip.
2. What is the typical droplet size range of a Dry Fog Humidifier Nozzle?
The nozzle produces droplets typically in the range of 5–7.5 microns, depending on air pressure, water pressure, and nozzle configuration.
3. What are the recommended operating air and water pressures?
Generally, the system operates at 0.3–0.35 MPa air pressure and low-to-medium water pressure around 0.2–0.3 MPa for stable atomization.
4. What is the air consumption per Dry Fog Humidifier Nozzle?
Air consumption typically ranges from 29 N.L/min to 116 N.L/min depending on the number of nozzles in the system.
5. What is the water flow rate per nozzle?
Standard flow rate is approximately 2.4 L/H per nozzle under optimal operating conditions.
6. Can multiple Dry Fog Humidifier Nozzles be operated in a single system?
Yes, systems are commonly designed for 1 to 4 nozzles, depending on compressor capacity and required humidification load.
7. What materials are used for nozzle construction?
Nozzles are typically manufactured using stainless steel (SS304/SS316) or corrosion-resistant alloys for durability and chemical resistance.
8. What is the atomization mechanism inside the nozzle?
Atomization occurs through high-velocity air shear, internal mixing chamber turbulence, and secondary breakup caused by supersonic airflow impact.
9. Is filtration required before water enters the nozzle?
Yes, fine filtration (typically 5–10 micron filtration) is recommended to prevent clogging and maintain consistent droplet formation.
