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.

Space-saving sterilization light source UV-CCL

This is a UV-CCL (Cold Cathode Sterilization Lamp). It is a space-saving sterilization light source that achieves compactness and energy concentration through bending processing. - The straight tube length of 680mm has been compacted to just 78mm in diameter! - It is resistant to flickering, and there is almost no reduction in lifespan due to the ON/OFF of the power supply! - It has a long lifespan of 15,000 hours! In UV sterilization devices equipped with this light source, after 30 minutes of operation, 90.7% of airborne bacteria are inactivated, after 60 minutes, 99.54% are inactivated, and after 90 minutes, 99.99% are inactivated. Test chamber: 25㎥ (equivalent to about 6.6 tatami mats) Test bacterial species: Staphylococcus epidermidis Test environment: 27℃, 40% RH

• Ultraviolet irradiation equipment

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.

• Ultraviolet irradiation equipment

Long-lasting sterilization lamp UV-CCL with strong power ON/OFF capability.

Features of UV-CCL 1. Strong against power ON/OFF and long lifespan Due to the absence of emitter coating, there is almost no degradation in lifespan from repeated ON/OFF cycles. 2. Various shapes and sizes Conventional sterilization light sources have challenges such as inflexibility in shape and size. UV-CCL uses specialized glass from Nippon Electric Glass (NEG) and can be bent at low temperatures of 700 degrees. This allows for compact designs, enabling the selection of light sources suitable for various applications and locations. 3. Energy concentration Bending processing concentrates energy and efficiently irradiates ultraviolet light. Compared to CCL in straight tube form, it achieves an increase in ultraviolet intensity.

● The production time for casting prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly creating sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be created in a single molding process. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.
