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.*

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. This is recommended for making doors with touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Allows for face recognition along with mask detection and body temperature measurement simultaneously. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and notifies via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.
