Cold-formed ring processing—demonstrating high pressure resistance and pull-out prevention through uniform ring processing without welding!—for connecting water supply pipes made of stainless steel pipes.

High pressure resistance and draw-in prevention are achieved through uniform ring processing without welding!

The rolling ring processing is a method of expanding a pipe into a ring shape. By performing the rolling process without welding the ring and the pipe, uniform ring processing becomes possible. It is compatible with the piping of connected water supply pipes made of stainless steel pipes. We produce in our factory and provide high-quality, uniform products. Please feel free to contact us when you need our services. 【Features】 ■ Uniform ring processing ■ Compatible with the piping of connected water supply pipes made of stainless steel ■ High pressure resistance ■ High pull-out resistance ■ Quality is stable as processing is done in our own factory ■ Made of stainless steel, excellent corrosion resistance, and environmentally friendly *For more details, please refer to the PDF document or feel free to contact us.

• Piping Equipment

Simple and speedy. A piping system that achieves outstanding labor savings.

Meiwa Kogyo's Grooved Joint is a one-touch mechanical joint system that integrates stainless steel pipes and fittings, suitable for a wide range of applications including building equipment piping, fire protection equipment piping, piping for various plant devices, and water supply and drainage piping. The one-touch design allows for speedy installation without the need for specialized piping techniques, enabling labor-saving and manpower-reducing measures on site. Additionally, since it uses stainless steel, there is no occurrence of red water, ensuring excellent piping quality and hygiene. It has also obtained fire protection certification, making it suitable for use in fire protection equipment connection water supply pipes. ☆ Benefits of the Grooved Joint ☆ Point 1 [No Expertise Required] There is no difference in sealing performance regardless of who performs the installation. The installation can be confirmed with the stopper attachment. Point 2 [Easy Installation] Simply insert the spigot into the socket and rotate to complete the installation. No tools are required for sizes up to 100A, allowing for manual installation. Point 3 [Cost Reduction] By shortening installation time, installation costs can be significantly reduced. It is also possible to shift from skilled workers to general workers.

Significantly reduces the effort required for cleaning and inspection compared to conventional bucket strainers!

The Glow Bucket Strainer is a product that allows for easy and safe cleaning and inspection. When opening the upper cover, there is no need for any bolt or nut tightening work; the upper cover can be removed with a single touch. Maintenance can be performed without tools for body diameters up to 150A. The product weight has been reduced to about one-third compared to conventional flange types, making it easier to handle. Since the face-to-face dimensions and filtration area can be customized, it can be replaced in existing spaces. 【Features】 ■ Easy and safe cleaning and inspection ■ Upper cover can be removed with a single touch ■ Safety is ensured during opening operations from above ■ Lightweight and compact ■ Face-to-face dimensions and filtration area can be customized *For more details, please refer to the PDF document or feel free to contact us.

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.
