Notice of participation in the Okayama Technology Exhibition (OTEX) 2020 from January 23 (Thursday) to January 24 (Friday), 2020.

It is recommended for spot use and installation in existing setups. Although it is compact, it can be used effectively at 600L/h.

The "Steri Mini" from HSP Corporation is a super hypochlorous acid generation device characterized by its compact size and lightweight design. Inside the device, the pH of sodium hypochlorite is stably adjusted to a weakly acidic level, allowing you to use freshly generated super hypochlorous water with adjusted concentration and pH simply by turning on the tap whenever you need it. The "Steri Mini," the smallest generation device, is easy to install and can be used on the same day as installation if done quickly. Despite its small size, it can generate 600 liters of water per hour, eliminating the stress of waiting for water to accumulate. The super hypochlorous water produced by the "Steri Mini" can be used for washing food, wiping, soaking, and handwashing. It can also be used with the dedicated portable sprayer "Sterimai" or a dedicated spray bottle. *For more details, please refer to the catalog or feel free to contact us. [Sample Available] We are offering free samples of super hypochlorous water. If you consult us about your intended use and application methods, we will provide you with an appropriate sample of super hypochlorous water along with recommended usage information.

[For bacteria and virus prevention!] An essential item for the upcoming season. Use Steri Mai in places where bacteria and viruses are a concern!

The top two environmental concerns in facilities are "odor" and "bacteria/viruses"! According to a survey conducted in medical facilities, the two main issues of concern regarding the environment within these facilities are "odor" and "hospital-acquired infections." Particularly during the winter season, which coincides with the outbreak of viruses and bacteria, maintaining hygiene within the facility becomes a significant challenge. The Steri-Mai is a dedicated portable sprayer that nebulizes super hypochlorous acid into a fine mist. It not only keeps the air within the facility clean but also decomposes odors from restrooms and food, allowing for simultaneous disinfection and deodorization. 【Features】 ■ 12 levels of spray volume control Achieve the appropriate spraying conditions for the environment with adjustable spray volume and intermittent timer. ■ Long lifespan & energy-saving LED lamp ■ Uses ultrasonic transducer Creates a fine mist of super hypochlorous acid at approximately 3 micrometers. ■ Excellent quietness ■ Simultaneous disinfection, deodorization, and humidification possible Maximum spray volume of 300ml/h. Can be used as a humidifier during the dry winter season. *For more details, please refer to the catalog or feel free to contact us.

We are pleased to announce that Gywood has been recommended as a featured building material in the special project "Recommended Building Materials" at the Housing Business Fair within the comprehensive exhibition for housing, architecture, and real estate [BREX Kansai]. We will be exhibiting in the "Recommended Building Materials and Equipment" zone, where professionals from the field gather to showcase their recommended materials. We invite everyone to stop by and visit us.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.
