Notice of Acquisition of Inactivation Effect Data for Floating Viruses/Aerosols Including the Novel Coronavirus

By installing supply ducts for ducted air conditioning units and external air handling units on the secondary side, ions are supplied from all indoor air supply outlets, achieving virus sterilization, deodorization, and energy-saving air conditioning.

By installing AQS in the air supply section of the ventilation system, the air quality and hygiene levels of the ventilated indoor environment will dramatically improve. Odors generated from outdoor air and indoor sources are detected and identified, and are reliably removed through oxygen ion reactions. Additionally, by measuring and detecting the generation capacity of oxygen ions, as well as indoor and outdoor air quality, air supply volume, and humidity with sensors, it becomes possible to quantify the invisible air and generate the appropriate ions indoors, thereby consistently creating an optimal indoor environment. Furthermore, by monitoring the data measured by air measurement sensors, it is possible to confirm that the indoor air, which changes daily, is being maintained hygienically. It is possible to disinfect airborne bacteria, with disinfection effectiveness data nearing 90%. Installation in the air supply duct allows for infection control in indoor spaces. It is possible to reduce the air conditioning airflow and hygienically increase the proportion of air that is reused (heat recovery) that is expelled outdoors. - Neutralization and removal of airborne bacteria (mold, bacteria, yeast) and odor substances (tobacco, ammonia, hydrogen sulfide). - Effectiveness against viruses, pollen, PM2.5, and VOCs, which can impact human health. - Prevention of hospital-acquired infections.

A visible and verifiable indoor air environment! Prompt remote control enables appropriate measures to be taken.

By logging into the web browser or customer portal application, you can view user-specific information regarding the operational status of the Ionair device and the ionized indoor environment. Additionally, the overview includes communication status, indoor air quality assessment, device and sensor status, and operational summaries, with all information related to the user's device recorded in the central database "Ionair DataCenter." In particular, with the help of "machine learning" algorithms, descriptions regarding air quality, operational status, and recommended maintenance tasks are generated from the data. In the event of a malfunction, this information can be used to quickly and remotely implement appropriate measures. *For more details, please refer to the PDF materials or feel free to contact us.*

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.

We have introduced the commercial aroma diffuser "Majesta Fragrance" to a cabaret club in Tokyo. The selected scent is "Royale," which offers a sense of calm and elegance. It spreads naturally throughout the floor, creating a high-quality space that satisfies the five senses. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in enhancing your store's scent experience, please feel free to contact us.

We have released a catalog for a trial version of a conceptual skills course designed to efficiently develop logical thinking and problem-solving skills in a short period. The course is structured in three levels, from basic to practical and applied, supporting skill enhancement directly related to work through video viewing, exercises, and detailed feedback. There is also a free trial version available, lasting about 10 to 20 minutes, allowing you to easily check the course content and approach. It is ideal for promotion and advancement exam preparation, as well as for developing the next generation of leaders, with a proven track record in many companies.
