Energy Saving Dry Fog Humidification System
Advantages
- Maintain sheet water retention between 6-8%
- Significant decrease in crack failure, about 80%
- Pasting failure also decreases by 80% (in combination with with the decreased crack failure)
- Stabilized folding accuracy.
- Improved punching accuracy
- Reduced print defects to to paper powder remnants
- Comparison of Failure Reports from before and after the installation of a humidification system

Dry Fog is an extremely fine uniform mist with a Sauter mean droplet size of 7.5μm.
The droplets are never larger (i.e. 40μm) which makes dry humidification possible.
Another advantage of the AKIMist "E" is that it can spray Dry Fog at a maximum rate of up to 3.8 GPH.
2. Minimized Energy Consumption
Because of Dry Fog the AKIMist "E" can humidify precisely and effeciently directly where it is needed.

Feature reports before and after
By reducing failures caused by low humidity,cracks and pasting failures, the total failure rate is greatly reduced.
*1) Comparison between the periods Nov. 2009 to Apr. 2010 (Before) and Nov. 2011 to Apr. 2012 (After)
*2) No evidence for fogging benefit found for scratch, oil spot and other failures
Examples
Why doesn't dry fog get wet?
Small bubbles/water droplets do not wet anything because they bounce back from the surface they touch. As it surface tension is high, compare to a bigger bubble/water droplet, it will not burst and wet the environment.
Dry Fog is a very fine fog with an average mean droplet diameter of 10 μm or less. Therefore, the fog sprayed from our AKIJet® nozzles will never burst and wet objects when spraying in a close room, above machine and operators.
