[Exhibition Announcement] We will be exhibiting at the Construction DX Exhibition [Tokyo] (within JAPAN BUILD).

[Industry First!] Automatic detection of differences between floor plans, longitudinal sections, and cross sections.

The integration navigator is a drawing consistency check tool that allows for intuitive verification of discrepancies in 2D drawings. By clicking on a measurement point, corresponding floor plans, cross-sections, and longitudinal sections are displayed side by side on one screen, enabling smooth verification of consistency between drawings. Additionally, cross-sectional lines can be overlaid on the floor plan, making it easy to identify where discrepancies occur at a glance. Tasks that were previously done by comparing paper drawings can now be easily completed on a PC, significantly reducing the burden on field personnel. It features user-friendly operations that allow even those unfamiliar with PCs to efficiently progress through multiple drawings while checking and registering necessary information simply by clicking on text in the drawings.

A CAD specifically for civil engineering, born from the voices of the field.

"J-CIVIL" is an add-on (plugin) software for the civil engineering industry that can be integrated with the DWG-compatible CAD software "ARES." It offers functionalities and usability similar to those of globally standard CAD software while being available at a price comparable to general-purpose CAD, thus alleviating the high costs that have been a barrier to adoption. While there are diverse needs in civil engineering sites, it aims to position itself as the standard CAD for civil engineering by focusing on the core, frequently used features to eliminate over-specification.

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.

Hotron's vehicle detection sensors allow you to search for products that meet your needs from three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles and notify you with a rotating light, or switch the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

We are pleased to announce that we will fully model change the wall-mounted 3L electric water heater "ESW03/M3 series," which has been widely appreciated for handwashing purposes, and it will be newly released in December 2025. The new model will feature a front cover that takes design aspects into consideration, resulting in a sleek appearance, and we have also reviewed the water supply pressure and installation methods, significantly improving convenience compared to the previous products. We kindly ask you to consider this opportunity. 【Main changes from the old product】 1) A front cover is included. The piping connection part is concealed even when installed in an exposed manner, taking design aspects into account. 2) Improved piping connection ports and changes in the method of fixing to the wall have enhanced the ease of installation. 3) The primary side water supply pressure has been changed from 0.5MPa to 0.75MPa.
