basic information

**Features** Naias delivers water solely through the pressure of nitrogen gas. **Principle of Water Delivery** The firefighting water in the tank is constantly pressurized with nitrogen gas, and in emergencies, it is automatically delivered by that pressure, requiring no electricity. **No Electricity Required** Electricity is not needed as a power source for water delivery. It can be used even during power outages caused by disasters such as earthquakes. **N2 Effect** Since it is constantly pressurized with N2 gas, it suppresses the oxidation of water quality, corrosion of cast iron pipes, and the proliferation of bacteria, maintaining water quality for an extended period. **Ideal Water Discharge** It can discharge water at a constant pressure, ranging from small amounts to over 5000L/min. Additionally, there is minimal pulsation during discharge, allowing for stable water delivery. **For more 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
