basic information

**Features of the Sprinkler Fire Extinguishing Device "Naias"** ■ No Electricity Required Since it does not use a power pump for water supply, electrical work (200V) is not necessary. Even during power outages due to disasters, it can discharge water without emergency power equipment. ■ No Water Supply Required Water is supplied from a faucet via a hose when needed, eliminating the need for plumbing work. Integration with existing equipment is easy without any water supply interruption during the construction period. ■ Stable Water Supply Ensures a stable discharge volume and pressure regardless of water supply pressure or outages. ■ Low Cost & Compact No need for an emergency generator. The fire extinguishing device is compactly integrated, and installation is as simple as placing it down. Its simple structure results in fewer malfunctions and easy maintenance. ■ Nitrogen Gas Effect The water in the tank is sealed with inert nitrogen gas, preventing decay. It suppresses oxidation of water quality, corrosion of pipes, and bacterial growth. *For other functions and details, please download the catalog.*

Our company was established in 1989 with the mission of selling and maintaining pumps and blowers that protect the lifelines of daily life. However, we took the impact of the Great Hanshin Earthquake in 1995 seriously, where the majority of fire extinguishing devices failed to function due to power outages, leading to an escalation of damage. In response, we developed the Nias fire extinguishing device, which is designed to operate in any disaster situation. Taking this opportunity, we have actively expanded our business areas through mergers and acquisitions with various companies and technological partnerships with overseas firms, focusing on the theme of "people, water, and air." We will continue to enhance our corporate value to contribute to building a richer future. Capital: 294.75 million yen Number of employees (consolidated): 180
