Underfloor Ventilation Series "Turbine Unit Type Ai"

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.

Underfloor ventilation "Kazetaro"

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

The underfloor ventilation "Kazetaro" maintains a comfortable condition for wood by forcibly introducing air into the underfloor space. It is particularly effective in eliminating condensation. Underfloor ventilation also affects the indoor environment, reducing the conditions for the growth of dust mites and mold, which benefits the health of the family. The Kazetaro unit uses a hybrid sensor to detect the amount of water vapor (humidity) in the outside air, and the hybrid controller independently controls the Kazetaro blower type and Kazetaro mixer type, creating optimal ventilation operation for the wood under the floor. 【Features】 ○ Improves ventilation effectiveness to prevent pest breeding ○ Forcibly introduces air into the underfloor space to prevent condensation ○ Maintains a comfortable condition for wood, extending the lifespan of the building ○ Reduces the conditions for the growth of dust mites and mold, making the indoor environment comfortable For more details, please contact us or download the catalog.

Underfloor electronic dehumidification unit 'DRY PRO' Ver3

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.

Cloud voicemail and message storage service

  • NEW
  • PRODUCT

What is Cloud Voicemail? It is an internet service that stores messages in the cloud (on the internet) when you are unable to answer incoming calls, allowing you to check the recordings from your computer or smartphone. Unlike recording on the media of the phone itself, there is no limit to the recording time. A key feature is that it does not become busy since it is processed by a program in the cloud. It is also referred to as voicemail. ★ Check voicemail without going to the office or store Whether on holidays, during closed hours, or when returning home directly, visiting, or working remotely, with cloud voicemail, you can play back and check recorded messages from anywhere. ★ For job reports in professions that often go directly to the field For staff who frequently work outside and go directly to the site, it is useful for reporting the start and end of their work. It can handle a surge of calls at the same time. ★ If you want to use your existing phone number for cloud voicemail Please use the forwarding service or forwarding function of your phone company (such as Voice Warp) to forward to the 050 number issued by Rimophone.
