Prevents condensation for a long period of time without using electric power, realizing maintenance-free equipment inspection
G-Breath is a product that has been NETIS VE rated for its effectiveness in social infrastructure and public construction.
A special humidity control sheet that "breathes" protects electrical equipment and equipment from malfunctions and other condensation problems.
Even though I have waterproof measures, the equipment breaks down ... The cause is dew! ??
The image below is an example of condensation damage. Condensation is occurring inside the sealed power distribution board (left). As a result, corrosion occurs on the metal parts inside the switchboard (middle, right), which can lead to equipment failure, malfunction, and electrical leakage.
Solved with condensation prevention sheet "Humidity Control Sheet"!
NTT-AT 's anti-condensation sheet "Humidity Control Sheet" is a special sheet *1 with excellent humidity control properties that prevents condensation and can be used for a long time, enabling smart maintenance that reduces maintenance costs. Furthermore, it is an ecological product that is friendly to the environment because it does not use electricity.
* 1: A product that has higher moisture absorption and desorption capacity than silica gel and has passed a long-term reliability test for introduction into communication equipment.
Junction box: Dustproof / waterproof structure (IP55)

Three points to recommend "Humidity Control Sheet"
The amazing humidity control function shuts out condensation!
It absorbs moisture quickly when the humidity rises, just like breathing, and releases moisture quickly when the humidity drops, suppressing fluctuations in humidity and preventing condensation. The anti-condensation sheet "Humidity Control Sheet" is a product that complies with the RoHS Directive.
In our outdoor tests, the humidity inside the box without the anti-condensation sheet "Humidity Control Sheet" (blue) changes according to the outside air humidity (green), while the inside of the box with the anti-condensation sheet "Humidity Control Sheet" Humidity (red) always maintains a certain range of humidity.
【Measurement condition】
Test box volume: 13.9 liters (with a φ5 mm vent on the bottom)
Condensation prevention sheet "Humidity Control Sheet" (postcard size) installed on the lid
Measurement location: Outdoors in Tokyo
Measurement period: Excerpt from 2 weeks
Long life & maintenance free
Humidity Control Sheet wicks away moisture without the need for high temperatures or sun drying to regenerate its wicking ability. Therefore, it responds to daily humidity fluctuations. Performance is maintained for a long period *2 by repeatedly performing moisture absorption and desorption. In addition, since it is an ecological product that does not require electricity and does not require maintenance after installation, it reduces management effort and costs.
* 2: A communication infrastructure company with a track record of maintaining performance for about 10 years.(The usable period varies depending on the structure of the enclosure to be installed and the environmental conditions.)
Versatility regardless of construction location
The anti-condensation sheet "Humidity Control Sheet" does not require electricity and is thin and light, so it can be easily installed in small spaces or on curved surfaces. We offer 4 different sizes, from business card size to small and large, according to the volume of the box to be constructed.
