Disinfection effect of UV sterilizers on airborne bacteria.

Ceiling-mounted UV sterilization device for virus prevention and other measures.

The UV sterilization device FreshAir uses UV-C ultraviolet light to inactivate bacteria and viruses in the air. By being installed on the ceiling and providing 360° ultraviolet irradiation, it effectively sterilizes while circulating air with a fan. It is designed to be safe for human health, making it suitable for use in spaces where people are present, such as clinics, stores, and facilities, and can operate 24 hours a day as an air hygiene measure. Features of the UV sterilization device FreshAir: ■ Effective sterilization with 360° ultraviolet irradiation + fan suction Not only does it provide 360° ultraviolet irradiation, but it also directly exposes the air sucked in by the fan to the ultraviolet lamp for sterilization. ■ Ceiling-mounted design eliminates space concerns It can be safely installed in environments where there is no space for floor installation, such as areas where children run around or where individuals with mobility impairments are present. ■ Usable 24 hours a day in occupied environments It uses ozone-free lamps that generate minimal ozone. The ultraviolet light is also emitted horizontally by a horizontal plate. A safety evaluation test based on JIS C 7550 has been conducted by a third-party organization accredited with ISO 17025, confirming its safety for living spaces, allowing for 24-hour use in areas with people present.

Comparison of temperatures between cold cathode sterilization lamps and conventional sterilization lamps.

We compared the temperatures of cold cathode sterilization lamps and conventional hot cathode sterilization lamps. Measurements were taken at the electrode area and the center of the light source. The cold cathode sterilization lamp tended to have a lower temperature. We believe that the lower temperature can reduce the thermal impact on surrounding components.

Disinfection without leaving residues using deep ultraviolet light.

The UV sterilization device FreshAir disinfects the air around the unit and the air sucked in by the fan through ultraviolet (UV-C) irradiation. The UV-C irradiation acts on the DNA of bacteria and viruses, rendering them inactive by losing their ability to reproduce. Sterilization using ultraviolet light does not produce resistant bacteria and is a clean method that does not generate harmful byproducts. Features of FreshAir: 1. 360° UV irradiation + fan for disinfection Not only does it provide 360° UV irradiation, but the fan also directly exposes the sucked-in air to the UV lamp for disinfection. 2. Ceiling-mounted design, so it doesn't get in the way It can be safely installed in spaces where there is no room for floor installation, in environments where children are running around, or where individuals with physical disabilities are present. 3. Can be used in occupied environments, with confirmed safety for living spaces Uses ozone-free lamps that generate little ozone. The ultraviolet light is also irradiated horizontally by a horizontal plate. A safety evaluation test based on JIS C 7550 was conducted by a third-party organization accredited with ISO 17025, confirming safety for living spaces, allowing for 24-hour use in occupied areas. *For more details, please contact us.

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

In civil engineering sites, there are many instances where temporary roads, access routes, heavy machinery workspaces, and material storage areas use ground plates. Traditional steel plates are heavy, requiring large machinery for installation and removal, which can make work difficult in narrow sites. Hyper CLT ground plates are lightweight civil engineering CLT materials made from wooden CLT for civil use. A 5×10 plate weighs about 230 kg, and a 5×20 plate weighs about 460 kg, making them easy to handle even with small machinery, thus reducing the burden of transportation, installation, and removal. They are easy to use in sites with limited space or where the use of large machinery is difficult. They can be widely used for temporary roads, heavy machinery scaffolding, pathways within the site, and material storage protection, contributing to glare reduction, noise reduction, and environmental consideration. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," they are also recommended as materials for innovative ideas and safety measures in public works.

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.
