Notice of Participation in the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 14 (Wednesday) to December 16 (Friday), 2022.

Speedy cleaning with highly effective chlorine dioxide gas! Safe to use with high-precision concentration measurement and control.

We offer a "Space Disinfection System (Weraser Series)" that combines a wagon-type disinfection device that generates and releases chlorine dioxide gas with a gas concentration meter. *We can also respond to requests for the prototype and development of chlorine dioxide gas generation devices (with concentration adjustment functions). Using chlorine dioxide gas, which has excellent disinfection power and high diffusibility, disinfection is completed in a short time. This is a professional-grade disinfection system that utilizes our technology developed for disinfection systems for major pharmaceutical factories. 【Features】 ■ High disinfection effectiveness prevents bacterial growth and suppresses odors ■ Intelligent function manages the diffusion of chlorine dioxide gas ■ Collects chlorine dioxide gas to below 0.1 ppm using HEPA and activated carbon filters *In addition to the product catalog, we are currently offering materials that explain related systems and chlorine dioxide. You can view them via [PDF download]. Please feel free to [contact us].

Steripower (hypochlorous acid aqueous solution) is used. It is sprayed in a mist form of 7μm with a special nozzle. The micro-particles float in the air for a long time, enhancing the disinfection effect!

The droplet sprays sterilizing power (hypochlorous acid aqueous solution) from a movable dome, creating a safe space that has been disinfected. The main body features a stable trapezoidal wagon style that excels in functionality. Thanks to a special nozzle, the chemical solution is atomized into a mist of 7μm, allowing micro-particles to remain suspended in the air for an extended period, enhancing the disinfection effect. The adjustable dome allows for angle adjustments of the nozzle, enabling changes to the spray angle of the disinfectant (3 levels). (Note: Nozzle removal is an optional feature.) The intermittent operation function allows for savings on the chemical solution and enables long hours of operation. Equipped with multifunctional features such as deodorizing, air purification, and disinfection! *For more details, please download the PDF or feel free to contact us.

The command center for space disinfection! Measurement of gas to emission completed in 18 seconds!

The gas in the sterilization room is drawn into the measurement cell, and the ultraviolet light from the ultraviolet light-emitting diode is received by a photodiode. Concentration conversion is performed. Before measuring gas concentration, a zero point measurement is conducted with fresh air, and a light filter is inserted for K-point correction. After these calibrations, the gas concentration is measured. The measured gas is then discharged. This operation can be completed in [18 seconds]! *For more details, please download the PDF or feel free to contact us.

Wagon-type disinfection device! Releases chlorine dioxide gas at 20 m/s! Quickly diffuses in the space for disinfection. Communicates with a meter via wireless to control gas concentration.

The device generates chlorine dioxide gas from the supplied chlorine dioxide water and releases it from the arch. The supplied chlorine dioxide water is activated by a variable bubbling function to produce chlorine dioxide gas. The concentration of the generated gas is determined by an external measuring device and is released until it reaches the pre-set spatial gas concentration. The device and the measuring instrument are connected via a 2.4GHz radio wave (second-generation low-power data communication system), and the diffusion of chlorine dioxide gas is managed by the intelligent functions of both the device and the measuring instrument to enhance the disinfection effect in the room. After a set exposure time determined by the fumigation time setting function, gas recovery is performed. The rear HEPA filter and activated carbon filter recover and absorb chlorine dioxide gas to below 0.1 ppm. In this recovery mode, dust is also removed, and clean air is released. *For more details, please download the PDF or feel free to contact us.*

Protech Engineering will exhibit at the "Landslide Disaster Prevention Technology Forum '25 in Toyama," organized by the Japan Society for Slope Disaster Prevention Technology, scheduled to be held on Thursday, October 9, 2025. On that day, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆Exhibited Products◆ - Pile-type debris flow and driftwood countermeasures for non-flowing streams / Urban Guard (model display) Additionally, our representative will conduct a technical presentation, so we kindly invite you to attend.

Protech Engineering (Booth Number: 240) will be exhibiting at the "Hokkaido Construction Development Comprehensive Exhibition 2025," scheduled to be held on October 8 (Wednesday) and 9 (Thursday), 2025. On the day of the event, we will provide detailed explanations of the following disaster prevention products using models, panels, and various materials. ◆ Main Exhibited Products ◆ - Energy-absorbing rockfall protection fence / ARC Fence (model display) - Landslide debris protection fence / Slope Guard Fence Type LE (model display) - Pile-type (pile foundation) debris flow and driftwood countermeasure for non-flowing streams / Urban Guard - Avalanche prevention piles / Tri-Pile - Avalanche protection fence / Slope Guard Fence Type LS - High energy-absorbing rockfall protection fence / Macro Fence In addition, we will have a variety of materials on disaster prevention products developed independently by Protech Engineering, so we kindly invite you to visit our booth.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
