Is a underfloor ventilation fan necessary?

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-type blower. When there is a high amount of water vapor, only the diffusion-type blower operates, and when it is low, the exhaust ventilation system operates in conjunction, bringing in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and blowing with absolute humidity sensors POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and underfloor water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor moisture, condensation, and mold ○ Powerful exhaust and diffusion For more details, please contact us or download the catalog.

A comfortable indoor environment! Prevents condensation and extends the lifespan of the building.

The "Kazetaro" underfloor ventilation system forcibly introduces air into the crawl space, maintaining a comfortable condition for the wood. It is particularly effective in eliminating condensation. Underfloor ventilation also impacts the indoor environment, reducing conditions that promote the growth of dust mites and mold, thus benefiting the health of the family. The Kazetaro unit features a hybrid sensor that detects the amount of water vapor (humidity) in the outside air, and a hybrid controller that independently controls the Kazetaro blower type and Kazetaro mixing type, creating optimal ventilation operation for the wood in the crawl space. 【Features】 ○ Prevents the breeding of pests by improving ventilation effectiveness ○ Forcibly introduces air into the crawl space to prevent condensation ○ Maintains a comfortable condition for the wood, extending the lifespan of the building ○ Reduces conditions for the growth of dust mites and mold, creating a comfortable indoor environment For more details, please contact us or download the catalog.

Improved air conditioning efficiency! A ventilation system that eliminates the causes of condensation and prolongs the life of your home.

The "Kaze no Suke Blower 24" is a system that continuously ventilates the attic for 24 hours, lowering the air pressure compared to the forced-ventilated interior, which prevents chemical substances from flowing into the room and creates a safe living environment. It detects the temperature in the attic with a temperature sensor and allows for switching between strong and weak operation. Additionally, it features a condensation mode that is effective for removing condensation. 【Features】 ■ Discharges hot air and improves cooling efficiency - Reduces excessive use of air conditioning, benefiting family health and saving on electricity bills. ■ Shuts out condensation - Actively circulates air in the attic to minimize temperature differences, eliminating the causes of condensation and prolonging the life of the building. ■ Supports the health of the family and home - With high ventilation capacity, it effectively expels formaldehyde and VOCs from the attic to the outdoors. *For more details, please refer to the PDF document or feel free to contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

A system for driver terminals has been realized through API integration, promoting the optimization of the delivery process and improvement of services to customers. Seino Information Service Co., Ltd. and Briskola Co., Ltd. announce that they have adopted Briskola's full lifecycle API management product "BAMs Series" for the construction of a system utilizing APIs and the management of API connections with various business applications for driver terminals, aimed at improving delivery efficiency and achieving digitalization of logistics for Seino Transportation Co., Ltd. and transportation groups nationwide. By implementing Briskola's "BAMs Series" for API management in the delivery management system constructed through API integration, we will focus on responding to the expected increase in the number of API calls due to the anticipated increase in terminal numbers, as well as ensuring stable system operation and preventive detection. This will lead to improved operational efficiency for drivers and the provision of high-quality services to customers sending and receiving packages.

In this case study, we have received cooperation from Obayashi Corporation and Sankyu Inc., leaders at the forefront of the construction and logistics industries, to introduce their specific initiatives regarding "early detection of heatstroke risk" and "ensuring worker safety." Additionally, we have published an interview article with Obayashi Corporation, who contributed to the development of "GenVital LTE," as a "development story." As heatstroke risk has become a social issue, we encourage everyone in companies working on improving on-site productivity and safety measures for workers to read this for insights. GRIFFY will continue to contribute to creating safer and more comfortable working environments through DX solutions, including "GenVital LTE." ◾️ Obayashi Corporation (case study) ◾️ Sankyu Inc.

We conducted an RTK accuracy verification of the GNSS reference station (Hi-Target Vnet6plus receiver + choke ring antenna) installed at our company building. Generally, with a single-frequency GNSS, once the baseline length exceeds 10 km, it becomes impossible to consider the path through the ionosphere as the same, and the difference in ionospheric delay becomes a significant source of error. By using dual-frequency GNSS, it is possible to correct the delay based on the differences in delay caused by the frequency of the radio waves; however, it is still said to be effective only up to about 10 km. Why is that? We have published the verification results on our blog.
