Developed a carbon-neutral aluminum melting holding furnace [Published in the Iron and Steel News, October 23, 2023, page 5]

Introducing the forefront of development! Hydrogen combustion without carbon dioxide emissions! SHOEI is advancing the adaptation of its proven in-house burners for hydrogen use.

【New Development! Hydrogen Gas Burner Lineup】 ◇ High-Temperature Furnace Hydrogen Gas Burner (EIS-H2) Achieves a wide combustion range and stable combustion For heat treatment furnaces, melting furnaces, heating furnaces, deodorization devices, etc. ◇ Package Burner (BJ-H2) ◇ Fan-Equipped Package Burner (SP-H2) Provides stable flames even under high furnace pressure conditions, with good operability and maintainability; suitable for low-temperature fields such as drying furnaces, as well as various industrial furnaces and deodorization devices. ◇ Hydrogen Combustion Recuperative Burner (STBW-H2) Equipped with a waste heat recovery device (heat exchanger), capable of reducing fuel usage by about 30% in addition to decarbonization. Developed in collaboration with Tokyo Gas Co., Ltd. and Tokyo Gas Engineering Solutions Co., Ltd.! For aluminum melting holding furnaces, preheating, heat treatment furnaces, etc. ◇ Hydrogen Combustion Single-End Radiant Tube Burner (TRFH-H2) Indirect heating method utilizing radiant heat With an integrated heat exchanger, the burner efficiency is high at 75%. ◇ Hydrogen Combustion Duct Burner (SDC-H2) Converts duct burners mounted on hot air generation devices to hydrogen combustion Suitable for various drying furnaces such as painting drying and food drying.

In the face of uncertainty regarding future energy supply, we are advancing efforts towards high-efficiency "electrification" and "hybridization" based on gas combustion furnaces.

**Electrification of Thermal Equipment** In an uncertain future for energy supply, we are responding to high-efficiency electrification based on proven thermal equipment (combustion furnaces) to offer multiple options to our customers as an industrial furnace manufacturer. The electric hot air generator (AH-E) can replace our gas combustion type without significant changes to the equipment layout, allowing for electrification. **Hybrid Heating of Electric and Combustion Types** We have numerous achievements not only in fully electrifying thermal equipment but also in hybrid heating that combines the advantages of combustion types. We address challenges such as "securing green power, reducing costs, and ensuring power capacity" through hybrid solutions with combustion types. In addition to improving the efficiency of electric systems, energy-saving systems that utilize waste heat for gas burners are also possible. By incorporating hydrogen gas burners, we achieve carbon neutrality! **We Conduct Practical Verification Tests** We conduct various heating tests at the newly established "Thermal Technology Research Institute" within the Horyuji Center. Among these, the "QCO Test Facility" allows for heating tests with four different heat sources! We propose thermal equipment suitable for workpieces using gas, electric, hydrogen, and hybrid heat sources.

Our company will be exhibiting at the "Green Cross Exhibition 2026 in Sapporo." Duration: September 16 (Wednesday) to 18 (Friday), 2026 - 16th (Wednesday) 10:00 AM to 5:00 PM - 17th (Thursday) 9:00 AM to 5:00 PM - 18th (Friday) 9:00 AM to 3:00 PM Venue: Sapporo City Sports Exchange Facility Tsudome (Sapporo City, Hokkaido) We look forward to your visit.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

We have introduced Majesta Fragrance to a nightclub in Yokosuka City, Kanagawa Prefecture, creating a fragrant atmosphere throughout the floor. The model we have introduced is the "MF-02S," which costs 8,800 yen per month (tax included). The scent you have chosen this time is "Sabon," a high-quality soap fragrance reminiscent of luxury hotel amenities. Its clean and transparent refreshing scent spreads throughout the entire floor, warmly welcoming customers who visit. By introducing scent design to the nightclub, we can enhance the extraordinary experience and create a memorable space that lingers not only visually but also through "scent." Majesta Fragrance offers a rental service for commercial aroma diffusers, and we also provide a free trial installation. If you are interested in scent design, please feel free to contact us.

In the July 8, 2026 issue of Air Conditioning Times, we featured "Flex Chamber" and "SS Premier" in a duct special.

SS Premier has won an award at the 24th Environmental and Equipment Design Awards. This award is organized by the General Incorporated Association of Architectural Equipment Comprehensive Association and recognizes outstanding efforts in environmental and equipment design. We will continue to strive for further improvements in quality and technology.
