We have prepared BIM-compatible data for the rooftop multipurpose unit "Hatokotto."

  • PRODUCT

"HATOCOT," which has been in use for over 30 years since its release, is widely applicable not only for new constructions but also for renovations and upgrades of air conditioning systems, having been adopted in over 15,000 sites. By modularizing pigeon loft construction, we provide numerous benefits such as shortened construction periods, labor savings, reduced rooftop weight, and improved maintenance during inspections and repairs. In response to the recent trend of applying BIM in the construction industry, we have prepared BIM-compatible family data for "HATOCOT" to ensure its adoption in an even wider range of sites. By utilizing the family data, tasks such as cost estimation and weight calculations during the design phase become easier, enabling further improvements in productivity and labor savings. *For BIM data, please contact us or download it from the official website (membership registration required).

Released a video of the Silent Vacuum Drainage System.

  • PRODUCT

The Silent Vacuum Drainage System is... When installing toilets or similar facilities in basements, it is common to use a pressurized system with a sewage tank and a sewage pump to pump up the wastewater. However, a minimal amount of wastewater often remains in the sewage tank, leading to unpleasant odors. Additionally, when trying to install toilets or water facilities in existing buildings, it can be difficult to secure the usage conditions of the lower floors and the slope of the drainage pipes, which may lead to abandonment of the project. To address these issues, a vacuum-based drainage system has been developed as an alternative to the pressurized system. However, many existing systems apply vacuum sewage systems that use lift-up methods and gas-liquid mixed suction, which can cause noise and vibration issues. This system is a Silent Vacuum Drainage System that can eliminate noise and vibration problems by using a method that does not involve air suction. Model units are available for viewing. Please feel free to contact us.

We will sell the product "Mini Cactus," which can lower the alarm water level for the pressure drainage system "SaniSpeed Plus." (Effective for leaks during malfunctions)

  • PRODUCT

The pressure drainage system "Sanipump Series" drains water using the power of a pump, freeing you from the constraints of drainage slope. Sanispeed Plus is ideal for general wastewater, such as drain drainage from refrigerated showcases and indirect drainage. There is an optional overflow alarm device, "Sanisensor/Sanialarm," to prevent leaks in case of a malfunction. When connecting drainage fixtures with low overflow edges, such as drain drainage from refrigerated showcases or indirect drainage, it is possible for water to overflow from the fixture before the alarm is triggered. In such cases, using the Mini Cactus can lower the alarm water level to 150 mm. We have released an introduction video for the Mini Cactus, so please take a look.
