An Oxygen Reduction System continuously lowers the oxygen concentration in a protected room, typically to around 15 percent, by injecting nitrogen so that most materials cannot ignite while the space stays safely breathable. Standardized in EN 16750, in data centers this hypoxic approach prevents fire rather than suppressing it, avoiding both water and discharge damage in critical rooms.
