Case C – 2
Provides low-humidity air to shorten drying time / improve productivity.
![](/wp/wp-content/uploads/2023/09/thum3-5.png)
Before introduction
Outside air is introduced into the conveyor.
Drying time : 1,200 sec.
After introduction
Low-humidity air is introduced into the conveyor.
Drying time : 600 sec.
Purpose DCondensation control
Case D – 1
Supplies low-humidity air to prevent condensation on low-temperature wall surfaces in the room.
![](/wp/wp-content/uploads/2023/09/ondokanri_12_500px-e1695640818456.png)
Before introduction
Indoor environment with condensation generation : 18.0 °C 100 %
![](/wp/wp-content/uploads/2023/09/ondokanri_13_500px-e1695640842950.png)
After introduction
Indoor environment : Achieved a significant reduction in humidity to 28.8 % at 27.3 °C. / Condensation was resolved, and mold floor slip concerns were eliminated to a large extent.
Case D – 2
Supplies low-humidity air to prevent condensation in low-temperature areas of ceilings.
![](/wp/wp-content/uploads/2023/09/thum3v-9.jpg)
Before introduction
Natural drying with a ceiling ventilation fan.
![](/wp/wp-content/uploads/2023/09/thum3v-8.jpg)
After introduction
Dehumidified air significantly improves condensation. Ceiling condensation leakage / mold was also improved at the same time.
Case D – 3
Supplying low-humidity air to the cargo handling room to prevent wall condensation at low temperatures.
![](/wp/wp-content/uploads/2023/09/ondokanri_18_500px.png)
Before introduction
