Even with a waterproof structure, the internal temperature can drop by just a few degrees, leading to high humidity and condensation. Are you using it beyond the specified humidity range of the product?
I never imagined that the cause of the malfunction would be "humidity"! The product has a waterproof structure with a specified humidity range of 20% to 80%. During daytime inspections, the internal temperature was 25°C and the humidity was 60%, which is an acceptable environment. However, it malfunctioned later. Upon investigating the cause, I found that the humidity inside had risen at night! Why? At a temperature of 25°C and humidity of 60%, the dew point temperature at which condensation begins is 16°C. Just a few degrees drop in temperature can lead to high humidity and condensation. (Relative) humidity % = Actual amount of water vapor in the air / Amount of water vapor that can be held in the air (saturated water vapor amount) x 100. The saturated water vapor amount in the denominator decreases as the temperature drops and increases as the temperature rises. Therefore, even if the amount of water vapor in the air does not change, if the temperature drops, the humidity will rise. Conversely, if the temperature rises, the humidity will drop, making it a phenomenon that is not easily noticed. The humidity inside the product fluctuates between medium to high humidity levels, potentially exceeding the specified humidity range of the product. Without knowing this situation, damage can occur, leading to sudden malfunctions (such as poor contact, power loss, decreased insulation resistance, etc.) one day. Especially in infrastructure facilities, a malfunction of just one piece of equipment cannot be overlooked. Problems can arise whether the humidity is too high or too low.

basic information
Condensation Prevention Sheet "G-Breath" 【Features】 ■ It absorbs moisture when humidity rises without using electricity, and releases the absorbed water vapor back into the air when humidity decreases, thereby regulating humidity, suppressing fluctuations, and preventing condensation. It also avoids excessive reduction of humidity that could lead to failures due to low humidity. ■ If it can repeatedly absorb and release moisture in response to fluctuations in humidity, it can be used for a long time. Unlike dehumidifying materials that continue to absorb moisture until they reach their limit, this reduces the need for replacement work, thus lowering operational costs. ■ It is thin, lightweight, and flexible, making it easy to install in existing small spaces. ■ The surface is made of insulating material, designed to absorb and release only water vapor. ■ Registered with the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System NETIS, registration number KT-180094-VE. This product has received VE evaluation. Regarding Size and Quantity ■ Available in four sizes: G-Breath L, M, postcard, and business card. The amount of water vapor inside the product varies depending on the product structure and usage environment. It is recommended to measure temperature and humidity to select the appropriate size and quantity based on the situation. * The effectiveness may vary depending on the product structure and usage environment. If high-humidity air or water enters from the outside, the effectiveness may decrease as more water vapor enters than the product's volume.

Waterproof structure product equipment ■ Control panels, distribution boards, terminal boxes ■ IoT, 5G, wireless base stations, antennas, radar ■ Surveillance cameras, monitoring equipment ■ Disaster prevention measuring instruments, sensors, communication devices ■ Building equipment, LED lighting, storage batteries, door horns ■ Electrical equipment for rivers, dams, ports, etc. ■ Power equipment and devices, solar power, wind power, storage batteries ■ Electrical equipment along railway lines, vehicles, station surveillance cameras, communication devices ■ Water supply and sewage facilities, remote monitoring devices ■ Broadcasting equipment and devices, satellite broadcasting equipment ■ Electrical equipment for traffic lights, ETC, etc. along roads, road information display equipment ■ Food-related devices ■ Increasing applications for use in humidity control during product transport and storage. The causes of condensation are various. We clarify the causes of occurrence and recommend appropriate countermeasures. * If high-humidity air or water from outside enters the product, the effect will decrease as more water vapor enters than the product volume. * It is not suitable for drying (low humidity) purposes as a humidity control material. * Condensation that occurs instantly in areas below the dew point temperature is effectively addressed by insulation measures for that area.
