About the "Automatic Stop Function after 10 Years" for the Underfloor and Attic Ventilation Fan Series.

Exhaust type + diffusion type unit! A subfloor ventilation series that detects humidity conditions and draws in dry air from beneath the floor.

The system detects the amount of water vapor (absolute humidity) and independently controls the exhaust ventilation system and the diffusion fan. When there is a high amount of water vapor, only the diffusion fan operates, and when it is low, the exhaust ventilation system also operates to bring in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and air supply with absolute humidity sensor POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor humidity, condensation, and mold ○ Powerful exhaust and diffusion For more details, please contact us or download the catalog.

24-hour ventilation (strong/weak, switchable) type

This product addresses the importance of ventilation highlighted by the Sick House Law. By specializing in underfloor ventilation, it responds to the negative pressure that occurs indoors due to ventilation fans (Type 3 ventilation system), which causes the indoor air to be depressurized, allowing air from under the floor to flow into the room. This characteristic prevents the inflow of dust, moisture, and other contaminants into the indoor environment that accompany the inflow of underfloor air during negative pressure conditions. Additionally, it simultaneously prevents the indoor inflow of harmful substances such as "formaldehyde." The dedicated controller detects the amount of water vapor in the outside air with sensors and automatically adjusts the ventilation system's operation strength, enhancing ventilation efficiency. 【Features】 - Effective against underfloor moisture, condensation, and mold - Powerful exhaust and mixing For more details, please contact us or download the catalog.

Contributes to the prevention of condensation and mold under the floor. A new model compatible with the foundation packing method has been introduced.

The "DRY PRO" Ver3 is an electronic dehumidifying and blowing unit for underfloor use, combining a Peltier cooling device with a dedicated stirring and diffusion-type blower. In addition to the diffusion-type model "TYPE-D" for foundation insulation construction, a new model "TYPE-C" compatible with foundation packing construction has been added to the lineup. It can dehumidify even in areas where moisture tends to accumulate by stirring a wide range of air. It helps suppress moisture and condensation under the floor, contributing to the prevention of mold, pests, and decay fungi in wooden parts under the floor. Furthermore, with the version upgrade in June 2024, a powerful dehumidification operation mode will be added. The surrounding temperature range for dehumidification operation (low-temperature dehumidification operation range) has been expanded, allowing operation at surrounding temperatures down to 5°C. 【Features】 ■ Easy installation with a φ22 drainage hole (no drainage pump required) ■ Automatic operation possible with a dedicated indoor controller ■ The direction of the aluminum duct of the blower can be set freely ■ Dehumidification capacity of 1800mL per day (depending on conditions) ■ Uses fluorine-free electronic cooling technology ■ Compatible with underfloor flooding sensors (optional) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce MotionCatch as a monitoring sensor that can be used to understand office occupancy. Using millimeter-wave radar and AI, it non-contactly detects human movement and occupancy status. Since it does not use a camera and does not record images, it can be considered for installation in places where cameras are difficult to place, such as conference rooms, private rooms, and work areas. 【Suitable for the following situations】 - Understanding whether conference rooms are actually in use - Monitoring occupancy and absence in private rooms and work areas - Checking if absences are prolonged It can be installed on walls or ceilings and has a design that easily blends into existing spaces. Product materials and a comparison table of monitoring sensors can be downloaded from the related catalog below. We also welcome inquiries regarding the conditions for rooms where installation is possible and the number of units, so please feel free to contact us.

One of the major strengths of the Hyper CLT sheet is that it is a technology registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS. The NETIS registration number is **"TH-250021-A."** In public works, it is important to explain to the client "why we are introducing it" and "what effects we expect" when adopting new materials. If it is a NETIS registered technology, it becomes easier to connect it to proposals for the utilization of new technologies and creative ideas. The Hyper CLT sheet is a civil engineering sheet that utilizes wood CLT. It is lightweight and easy to install and remove, and it has characteristics unique to wood, such as reducing summer heat reflection and noise, and fixing CO2. It is important to be able to propose it not just as "wooden sheets," but as a civil engineering technology registered with NETIS. The Hyper CLT sheet, which combines wood, NETIS, civil engineering, and CLT, is a new temporary material that makes it easier to clearly demonstrate the reasons for its introduction in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

The applications of Hyper CLT sheets are not limited to specific locations. Essentially, many civil engineering sites that have previously used steel plates are candidates for consideration. Wood CLT can be utilized in various places such as temporary roads, access routes, heavy machinery work yards, material yards, storage areas, temporary parking lots, and worker pathways. Of course, there are cases where steel plates are more suitable depending on site conditions, such as in areas with heavy loads or where heavy machinery needs to turn. The important thing is not to replace everything, but to use them appropriately according to the ground conditions, machinery, and intended use. Hyper CLT sheets are lightweight, easy to install and remove, and have unique characteristics of wood, such as reducing glare and metallic sounds, and fixing CO2. Furthermore, it is a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A."** By utilizing wood, NETIS, civil engineering, and CLT, it provides a new option for places that have previously used steel plates.
