Hypoxic Air Fire Preventive System

The unique solution for fire preventions and suppression—no water, no foam, no chemical extinguishing agents. The system is designed so that a fire in the data center is not created at all.

A unique system, which fully replaces the usual fire extinguishing equipment, allows preventing a fire with a zero fire risk in the protected area of the data center. The solution is designed in such a fashion so that primarily no fire could ever arise in the data center thanks to hypoxic air (oxygen reduced air). The principle of the hypoxic technology is the reduction and subsequent permanent maintenance of the oxygen content below 16% in the protected area of the data center, 24/7 throughout the building service life. The 16% oxygen concentration limit in the air is crucial for the combustion process. Air with a ratio of oxygen lowered below this critical limit makes it impossible to create a fire, but it is still completely safe for service personnel, which is also confirmed by the State Health Institute of the Czech Republic. This environment is approximately equivalent to pressure and air concentration at an altitude of 2700 meters.

How does it work? Ambient air (with 21% of oxygen) is drawn into the hypoxic generator where it is purified and turned hypoxic (air with oxygen content below 16%). The entire room of the data center is ventilated with hypoxic air, inhibiting fire ignition. Low oxygen air leaks from the room, thus completing the flow of air and ventilating the space. A control unit monitoring the room with oxygen sensors permanently ensures a stable and healthy low oxygen environment in the room.

Time to first reduce oxygen in the protected area from 20.9% to 15%* takes 16 hours. Calculated for air exchange (leakage taken into account) of max. 50% of total volume in 24 hours.
** Calculated for "free volume" - 50% of space filled with furniture means a 50% reduction in energy consumption.
*** In the case of a larger volume of the protected area, two, three, or more systems shall be used.
