To implement an accurate humidity control, we offer pneumatic nozzle-based humidification systems that are mounted with our unique impinging type nozzle. This technology differs from the impingement nozzles as it is the impact between the two fine fog jets that breaks down the water droplet to an even finer fog. The nozzle spacing and pressure outside nozzle are key to produce this Dry Fog spray. This is an original method of Ikeuchi. It is using an external mixing type of air-liquid mixing systems, halfway like air atomising nozzles as the compressed air and the liquid are mixed outside the nozzle. Thus, this impinging type of nozzle clogs the least in the range of pneumatic nozzles.

Our systems are composed of the humidifier and its ancillary devices such as RO units (for filtration and demineralization of the water) and control panels (for spray flow and drip controls) to humidify any type of application and industrial operations accurately and efficiently.

For additional systems:

  • Portable Dry fog humidifier set
  • AirAKI® Fogging system

The AKIMist ® “E”’s features

  • Energy efficient humidifier with pneumatic spray nozzles producing Dry Fog**.
  • With world-leading technology, our AKIMist®“E” produces ultra-fine “non-wetting” Dry Fog, which doesn’t wet the objects it touches.
  • It prevents dryness and static electricity, enabling higher manufactured product quality and lower defect rates.
  • The running cost is 1/5 of a comparable steam humidification
  • For spaying chemical solution, chemical-resistant AKIMist®“E” TN is available.

** We define Dry Fog as a very fine fog with a uniform mean droplet diameter (mean fog droplet size) of 10μm or less.
Because Dry Fog’s exceedingly fine spray droplets remain intact without bursting when they come into contact with objects such as walls and people, they do not wet the impacted surface and its nearby environment.
“Dry mist,” despite its similar name, has much larger droplets than Dry Fog and has no specified droplet diameter as part of its definition. Dry mist droplet sizes vary significantly by producer and product.

Additional accessories

The AKIMist®“E” Dry Fog Humidifier can come with mounting kits and UT adaptors to facilitate its installation and the spraying direction.

Additional cleaning kits are also provided as these nozzles are not considered as self-cleaning nozzles. Even when using demineralized water, the nozzle tips need to be cleaned on a regular basis to atomize properly without outside impurities such as dust particles.

Applications of the AKIMist®“E”

  • Static electricity prevention: Prevents/reduces troubles caused by static charge, such as product damage, (electrostatic damage) and debris/dust adhesion, etc.
  • Energy saving: The running-costs of our system are only 1/5 of a typical steam humidification system, resulting in drastic energy savings.
  • Cooling effects: The system also yields a cooling of about 2℃, reducing temperatures with evaporative cooling (using the principle of heat loss due to water evaporation of Dry Fog).
  • Health-related benefits: Maintaining a relative humidity level of 50% dramatically reduces cold viruses, influenza (flu) viruses and so forth, thus reducing worker absences caused by illness.
  • Disinfection, sterilization: in food factories, hospitals, pharmaceutical plants
