コーアツ List of Products and Services

The "Halon 1301 Fire Extinguishing System" has a high extinguishing power and excellent characteristics, such as not requiring pressure relief measures. The use of halon as a fire extinguishing agent was globally discontinued in 2010 to protect the Earth's ozone layer. However, in Japan, the "Fire Environment Network" was established under the guidance of the Ministry of Internal Affairs and Communications and the Ministry of the Environment. This network manages the halon database, suppresses the indiscriminate release of the extinguishing agent, and contributes to environmental conservation by recycling reusable halon. 【Features】 ■ Stable gas ■ No contamination from the extinguishing agent ■ Excellent electrical insulation ■ Radiates as a gas ■ No other pressurized devices needed *For more details, please refer to the PDF materials or feel free to contact us.

• Fire extinguishing equipment

The "NE-1" is a fire extinguishing system that uses the fire extinguishing agent "Novec 1230," which does not destroy the ozone layer and has an extremely low global warming potential. It is suitable for communication equipment rooms, computer rooms, electrical rooms, cable rooms, machine rooms, and small machine tools. We also offer a package type that includes all necessary equipment for the system, such as the extinguishing agent container, control equipment, and injection heads. 【Features】 - Utilizes the next-generation gas extinguishing agent "Novec 1230" developed by 3M - The extinguishing agent has an ozone depletion potential of zero, a global warming potential of less than 1, and excellent environmental characteristics with a residence time of 7.0 days in the atmosphere - High-speed release of the extinguishing agent within 10 seconds - Automatic extinguishing system linked with smoke detectors or heat detectors - Excellent electrical insulation properties *For more details, please refer to the PDF document or feel free to contact us.

This product is a package-type fire extinguishing system that compactly integrates the functions of "NN100." It is suitable for relatively small communication equipment rooms (communication machinery rooms, computer rooms), generator rooms, cable rooms, machinery rooms, electrical rooms, and art exhibition rooms (storage). 【Features】 ■ Space-saving and low cost ■ Uses nitrogen gas as the extinguishing agent, with an ozone depletion potential of zero and a global warming potential of zero ■ No thermal decomposition products from the extinguishing agent, leaving no contamination ■ Specific gravity close to air, ensuring sustained extinguishing effect ■ Automatic release via AND circuit *For more details, please refer to the PDF document or feel free to contact us.

The "NN100" is a fire extinguishing system with excellent fire extinguishing capabilities. Since nitrogen gas is stored as a gas, it does not affect precision instruments or artworks due to frost or condensation. By adopting a newly developed high-pressure filling container (30MPa), the number of containers required is significantly reduced compared to our conventional products. Additionally, with the container valve featuring pressure control (patented in Japan and the U.S.), the outlet pressure of the container can be reduced to 6.5MPa or below 10.8MPa, allowing the use of Sch40 or 80 piping. 【Features】 ■ Uses nitrogen gas, which makes up 78% of the atmosphere, as the extinguishing agent ■ No contamination from the extinguishing agent ■ Long-lasting extinguishing effectiveness ■ Excellent cost performance ■ Continuous monitoring function *For more details, please refer to the PDF document or feel free to contact us.

The "carbon dioxide fire extinguishing system" has been adopted for a long time among gas-based fire extinguishing systems and is a fully developed fire extinguishing technology. Since it was established by the Fire Service Act in 1961, it has achieved excellent fire extinguishing results in various fire protection targets. Carbon dioxide is low-cost and has the property of penetrating even the smallest gaps, making it suitable for localized extinguishing where the structure is complex and a large amount of extinguishing agent is required. 【Features】 ■ Stable gas ■ No contamination from the extinguishing agent ■ Excellent electrical insulation ■ Radiates as a gas ■ No need for other pressurized devices *For more details, please refer to the PDF materials or feel free to contact us.
