【Date: 2018/10/10】Free Seminar LED Lighting Fixture Exhibition & Explosion-Proof Lighting Industry Technical Seminar (Iwakuni City)

Reliability in explosion-proof areas is essential, and glare reduction along with high color rendering improves work efficiency! Compared to our conventional fluorescent fixtures, power consumption is reduced by approximately 55%!

Introducing the new explosion-proof LED light series, the 'LZBA series', designed to meet the high reliability required in explosion-proof areas and suitable for use in explosive hazardous locations Zone 1 and Zone 2! While equipped with high output equivalent to fluorescent lights, we have achieved a reduction in power consumption from 91W to 40.5W, approximately 55% less compared to our conventional explosion-proof fluorescent fixtures. Additionally, we have reviewed the design of the LED module and housing, achieving a lightweight and compact form. With glare reduction and high color rendering (Ra83), it also contributes to improving the work environment. ★ZONE 1 (Class 1 location): Areas where explosive atmospheres may be generated during normal operation of plants, etc. ★ZONE 2 (Class 2 location): Areas where explosive atmospheres are not likely to be generated during normal operation of plants, etc., and if they do occur during abnormal conditions, they exist only for a short time. 【Features】 ■ Three types to choose from (equivalent to 1-lamp and 2-lamp FHF32W high-output type, and equivalent to FHF16W high-output type) ■ Achieved approximately 27% weight reduction for 2-lamp and about 21% for 1-lamp compared to our conventional explosion-proof fluorescent fixtures ■ Size reduction of about 33% for the 1-lamp type *For more details, please refer to the materials.

Explosion-proof LED lighting fixtures LZLA series, ideal for replacing incandescent and circular fluorescent lamps in explosion-proof areas.

New Release of Explosion-Proof LED Lighting Fixtures (LZLA Series) Seiwa Electric Co., Ltd. has enhanced its lineup of LED lighting fixtures under the <Star Reds> series to meet diverse needs in the introduction of energy-saving equipment in factories and initiatives for the environment (Minamata Convention). We are pleased to announce the addition of the explosion-proof LED lighting fixtures "LZLA Series," which can be used in explosive hazardous areas Zone 1 and Zone 2, equivalent to incandescent lamps (100W, 200W) and high-output FHF32W (circular and compact fluorescent lamps). Orders will begin on May 15. The main body of the fixture utilizes aluminum die-casting, which excels in heat dissipation and lightweight design. By implementing effective heat dissipation measures, the operating temperature range has been increased to -20°C to +50°C (compared to our conventional LED products which are -20°C to +40°C), enhancing resistance to high-temperature environments. Additionally, it achieves a maintenance-free LED module lifespan of 60,000 hours while also possessing high durability and weather resistance.

Explosion-proof LED lighting fixtures using straight LED lamps compliant with the International Harmonized Explosion Protection Guidelines 2008 standard for explosion-proof areas such as chemical plants.

Launch of Explosion-Proof LED Lighting Fixtures (LZAB Series) These LED lighting fixtures can be installed in explosion-proof areas such as chemical plants, oil refineries, and hydrogen stations. The light source (lamp) can be replaced independently, allowing for reduced capital investment during lighting equipment updates compared to conventional integrated LED lighting fixtures. Additionally, it achieves brightness equivalent to a high-output FHF32 two-lamp setup while reducing power consumption by approximately 36% compared to traditional fluorescent lamps (based on our company's estimation conditions). It meets explosion-proof performance standards for Zone 1, Zone 2 areas, and hydrogen areas. ■ Product Features ○ Achieves brightness equivalent to a high-output FHF32 two-lamp setup, with power consumption reduced by approximately 36%. ○ Uses straight LED lamps as the light source. ○ Lamps can be replaced using the same method as conventional light sources (FLR/FHF). ○ Compatible with Zone 1, Zone 2 areas, and hydrogen areas.

Numerous lighting solutions for harsh environments! Explosion-proof and hydrogen sulfide-compatible products also help prevent workplace accidents.

Sewage treatment facilities, where water is always present, create a harsh environment for electrical equipment. Additionally, the hydrogen sulfide and digestion gases (methane) generated from wastewater can lead directly to occupational hazards. Our company offers a wide range of LED lighting fixtures equipped with high waterproof and moisture-proof performance, including flood-resistant types that can handle temporary flooding caused by heavy rain. We also conduct tests to confirm performance against corrosion from hydrogen sulfide, taking into account the facility and its installation environment. 【Features】 ■ High waterproof and moisture-proof performance ■ High reliability due to excellent weather resistance ■ Testing conducted to confirm performance as a countermeasure against hydrogen sulfide ■ Explosion-proof standards compliant with "Internationally Harmonized Guidelines and Technical Standards for Explosion Protection" *For more details, please refer to the materials. Feel free to contact us with any inquiries.

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.
