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.*

PERI products are used on construction sites around the world. This time, we would like to introduce the "Tassonaro Railway Bridge Renovation Project" in Italy. This historic railway bridge, spanning the Tassonaro River, underwent extensive renovation work in 2023. The reason for the renovation was the cracking of the concrete due to ground subsidence. Built in the 1930s with stone and white marble, this railway bridge is approximately 200 meters long and consists of nine arches. It survived both bombing and sabotage during World War II. To protect the bridge from seismic activity caused by the clay embankment, deep foundations were excavated down to 35 meters below the river surface during construction. Structural renovations were carried out inside the nine arches of the railway bridge using concrete and rebar. To ensure the partial preservation of the structure, PERI developed a custom special solution that combined multiple products and provided support for both the planning phase and on-site construction. PERI products: 1. VARIO GT24 (wall formwork) 2. RUNDFLEX (circular wall formwork) 3. PERI UP (modular scaffolding system) PERI Japan Co., Ltd.

Our company will exhibit at the "Disaster Prevention National Conference 2026 in Tottori." Dates: October 17 (Saturday) to 18 (Sunday), 2026 Venue: Ace Pack Future Center, around the Tottori Prefectural Art Museum We look forward to your visit.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily visible at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

VitaNet conducted a passenger information distribution using AccuNotify at Naha Airport as part of a demonstration project by the Okinawa General Bureau of the Ministry of Land, Infrastructure, Transport and Tourism. Information was notified to passengers' smartphones based on their location and timing, achieving a CTR of 14.9%, a user satisfaction rating of 4.77 out of 5, and a system operational rate of 100%. This demonstrated the potential to utilize the airport's passenger flow as a new digital customer touchpoint and advertising medium that allows for measurable effectiveness.
