The environmentally friendly special cleaning G-Eco method has been further enhanced, strengthening measures against the novel coronavirus (COVID-19)!

A cleaning agent that removes mold, tar, and dirt from inside and outside buildings without damaging building materials and without harming plants, animals, or the environment. It can also be used on wood surfaces.

It removes mold and algae, and also addresses the removal of viruses and bacteria. It restores the color of wood that has turned black due to ultraviolet rays by reversing the lignin component, while simultaneously eliminating mold. This cleaning agent is not just a mold remover that decolorizes mycelium and spores; it thoroughly eliminates mold from the root and can suppress reoccurrence in the long term. By having separate mold removers for wood and other materials, it achieves cost reduction, environmental consideration, and efficiency in work processes simultaneously. It uses components that are also used in food additives and is environmentally friendly. It does not affect plants or animals. It can be used not only on concrete, boards, stone materials, resin, and painted surfaces, but also on wooden parts (unpainted wood). 【Application Examples】 It can be used in food factories, beverage factories, seafood processing plants, dairy farms, pig farms, poultry farms, hospitals, nursing facilities, public facilities, bathing facilities, sports clubs, schools, kindergartens and daycare centers, office buildings, hotels, supermarkets, residences, indoor wallpaper, sukiya gates, wooden decks, and more. *For more details, please download the catalog or feel free to contact us.

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
