We have published a FAQ for the waterproof sleeve "Pipe-in-Sleeve" for underground and outer wall use.

[Official Release] Waterproof Sleeve for Underground Walls "Pipe-in-Sleeve" (Abbreviated as PIS) Reducing Labor at Construction Sites! Enhancing Waterproof Performance of Buildings!

■Recently, our "Pipe-in-Sleeve," showcased at the JECA Fair 2025, is officially released with great anticipation.■ In the underground wall section (underground beam sleeve), we have pre-treated the PVC sleeve and the outer space (gap) of the FEP with "waterproof treatment" at the factory, making it prefabricated for the site. On-site, there is no need for cumbersome work; after installing the PIS, basically only joint connections are required. It ensures stable waterproofing! Achieving work efficiency and promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction. <Features> ■ Excellent waterproof performance [Flood prevention and water resistance promotion] ■ Proposal for labor-saving at construction sites ■ Adaptable to individual project design specifications ■ Improved work efficiency, standardized quality, and enhanced maintainability [To Designers and Contractors] FEP pipe through-piping, bell mouth terminal installation, connection of different pipes (AQ type), and various connection parts of Eflex can be arranged according to the specifications of each construction site! Furthermore, it can also respond to unexpected water leaks! It combines maintenance and serviceability, making it a versatile and highly adaptable product. (Feel free to request drawings as well)

Streamlining on-site work through prefabrication! Additionally, improving the waterproof performance of buildings.

In the construction industry, there is always a demand for shorter construction periods and improved quality. In particular, the waterproofing treatment of the underground beam exterior wall is the most critical construction area for eliminating leakage risks and enhancing the safety of the building's power supply. Traditional methods often require complex waterproofing work on-site, leading to longer construction periods. However, the Pipe-in-Sleeve (PIS) system simplifies on-site work by prefabricating PVC sleeves and FEP pipes in the factory, contributing to shorter construction times. [Usage Scenarios] * Underground beam/exterior wall penetration * Underground penetration/power cable entry [Benefits of Implementation] * Labor-saving (reducing the burden on workers) * Shorter construction periods * Improved waterproof performance [For Designers and Contractors] FEP pull-through, bell mouth terminal installation, etc., can be customized to individual site specifications! Additionally, it can handle unexpected leaks! It is a versatile and highly adaptable product that also incorporates maintenance and serviceability. ● Be sure to check out the introduction video on YouTube, "Tome Taro Channel." * For more details, please request a catalog from "Contact Us," or view the PDF data from "Download."

[Coming Soon] An upgraded version of the beloved "Pipe-in-Sleeve"! "Pipe-in-Sleeve T-Type," abbreviated as PIS-T. In contrast to the PVC sleeve, a through pipe made of FEP has been pre-filled with waterproof material (sealant) at the factory, making it prefabricated. The T-type further features a "drainage PVC flange" welded with PVC material to the outer layer of the PVC sleeve. This method replaces the ring-shaped or band-shaped waterproof material on the outer circumference of the PVC sleeve, responding to strong requests from construction companies. <Features> ■ Excellent waterproofing due to prefabrication: Promotes flood prevention and water resistance ■ Labor-saving at construction sites! Reduces worker burden and prevents troubles in advance! ■ No skilled techniques required! Simplifies complex tasks! ■ Flexibility to accommodate individual design specifications of projects! ■ Improved work efficiency, standardized quality, and enhanced maintenance! [For Designers and Contractors] FEP pull-through, bell mouth terminal installation, etc., can be arranged according to individual site specifications! Additionally, it is equipped to handle unexpected leaks!

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

We have introduced Majesta Fragrance to a nightclub in Yokosuka City, Kanagawa Prefecture, creating a fragrant atmosphere throughout the floor. The model we have introduced is the "MF-02S," which costs 8,800 yen per month (tax included).

By introducing scent design to the nightclub, we can enhance the extraordinary experience and create a memorable space that lingers not only visually but also through "scent." Majesta Fragrance offers a rental service for commercial aroma diffusers, and we also provide a free trial installation. If you are interested in scent design, please feel free to contact us.

In the July 8, 2026 issue of Air Conditioning Times, we featured "Flex Chamber" and "SS Premier" in a duct special.

SS Premier has won an award at the 24th Environmental and Equipment Design Awards. This award is organized by the General Incorporated Association of Architectural Equipment Comprehensive Association and recognizes outstanding efforts in environmental and equipment design. We will continue to strive for further improvements in quality and technology.
