Reduce the risk of flooding in data centers through prefabrication!
[Coming Soon] An upgraded version of the beloved "Pipe-in-Sleeve"! 'PIS-T Type' The T type features a "drainage PVC flange" welded with the same material to the outer layer of the PVC sleeve, making it the ultimate solution for water intrusion prevention. In data centers, server downtime due to water intrusion can have serious impacts on business continuity, causing electrical shorts and equipment failures, which may lead to data loss and service interruptions. Our "Pipe-in-Sleeve T Type" is a prefabricated sleeve material! We propose a reliable water intrusion prevention solution to protect data centers from water! [Usage Scenarios] - Data center construction projects - Underground exterior walls with water intrusion risks - Locations where important information infrastructure needs protection [Benefits of Implementation] - Reduced risk of water intrusion - Shortened construction time and cost savings - Improved reliability due to high 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 also combines maintenance and serviceability, making it a versatile and highly adaptable product. *For more details, please request a catalog through "Contact Us" or view the PDF data via "Download."

*R2.6 Publication of National Transportation Document "Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings" *R3.4 (Public Foundation) Japan Sewerage New Technology Organization "Promotion of Waterproofing (Final Version)" The adoption of these measures is rapidly increasing in construction projects. "Pipe-in-Sleeve (PIS)" <Excerpt of Adoption Records from Local Governments> (Statistics from January to March 2026) - Osaka Prefecture ●● City) Communication equipment construction related to the expansion of ●●●● and others - Shizuoka Prefecture ●● City) Electrical equipment construction for the (tentative name) ●● District Center in fiscal year 7 - Kyoto Prefecture ●● City) Electrical equipment construction related to the construction of a new building at ●● City Hospital (Section 1) - Kanagawa Prefecture ●● City) Electrical equipment construction for the expansion of ●● Elementary School building No. 1, among others Due to the recent shortage of construction workers and skilled labor, while "easy installation" is possible, there are also materials/methods that underestimate waterproof performance, leading to an increasing trend of leakage problems in underground beams in recent years. To prevent leakage accidents that could lead to large-scale repair work later on, we advocate for the adoption of Pipe-in-Sleeve (abbreviated as PIS), which combines both "labor-saving at construction sites" and "maintaining the waterproof performance of buildings," as well as Pipe-in-Sleeve T-type (abbreviated as PIS-T).
