Notice of Participation in 【INCHEM TOKYO 2025】

A compact catalytic deodorization device that can be moved with casters! Because it is catalytic, it is more high-performance than filter types and more energy-efficient than direct combustion types.

This is a "compact catalytic deodorization device" that removes VOCs (volatile organic compounds) such as toluene, xylene, and ethyl acetate, as well as exhaust gases containing unpleasant odors, by means of oxidative decomposition treatment. It has been designed to be lightweight and compact to enable local exhaust and temporary use, and it is a portable deodorization device that can be moved to the necessary location by adding casters. 【Features】 - Compact catalytic deodorization devices with treatment air volumes of 1Nm3/min, 3Nm3/min, and 5Nm3/min - Easy-to-understand operation display, with simple touch panel controls - Lightweight and easy to move due to the casters - Optional dedicated software allows for remote monitoring and operation using Wi-Fi with tablet devices or smartphones - Structure designed for easy maintenance *For more details, please download the PDF or feel free to contact us. *Demo units are available for use, and tests can be conducted with solvents brought in.

Significant fuel savings possible! Odor control and safe exhaust treatment of VOC emissions.

The "catalytic deodorization device" is a system that oxidizes combustible substances, VOCs, and odors in exhaust gas by bringing them into contact with air through a catalyst, resulting in odorless and harmless emissions. Since it can initiate oxidation reactions at low temperatures (300°C to 350°C) below the ignition point, it consumes about one-third the fuel for preheating compared to direct combustion deodorization devices. Additionally, it is equipped with a built-in heat exchanger, and by adding a secondary heat exchanger, significant fuel savings can be achieved. 【Features】 ■ High deodorization efficiency with high-performance platinum-based catalysts ■ Low generation of nitrogen oxides, enabling low NOx operation ■ Negative pressure structure in the exhaust gas flow path within the device to prevent odor leaks ■ Compact integrated design with low flow resistance, reducing power consumption *For more details, please refer to the PDF document or feel free to contact us.

• Hazardous material processing

Space-saving type with easy operation! Achieve workplace environment improvement with a catalytic small deodorization device!

**[Problems Faced by Company A]** They were concerned about the deterioration of the workplace environment for employees caused by VOCs generated during the molding and coating drying processes of resin products. While combustion-type treatment devices are the most effective for VOC treatment, they struggled to find a device that met the condition of not threatening the 1.5m wide workspace between the dryers. Even when devices that could fit in the space were available, they often lacked sufficient processing capacity, leading to ongoing challenges. **[Implementation Effects]** The compact catalytic deodorization device, which is easy to operate with a touch panel, achieved a space-saving design of 120cm in width, 50cm in depth, and 70.5cm in height, while providing a processing capacity of over 3N?/min and a VOC removal efficiency of over 98%. After installation, the solvent odor that had been lingering in the workspace was reduced, creating a safer working environment. Employees have expressed high satisfaction, stating, "It has become easier to work" and "The solvent odor no longer clings to my clothes." ● For more details, please download the catalog or contact us.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Environmental Industry Expo 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition aims to pave the way for a sustainable future from the local community. It is a trade fair for environmental-related industries originating from the Minami-Shinshu region of Nagano Prefecture. Our company will introduce next-generation solutions for reducing environmental impact and effectively utilizing energy, including our "smokeless small incinerator" and "stove," along with product panels and case studies. No pre-registration is required, and admission is free. We sincerely look forward to your visit.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
