Hypoxic Air Fire Preventive System

Hypoxic Air Fire Preventive System

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 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 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.



  • Replacement of standard fire extinguishing equipment
  • No design limitations
  • Reduced fire resistance of structures - less than 30 minutes
  • Installation of heat and smoke removal equipment not required
  • Unlimited space of a fire zone
  • No need to install an air handling unit to ensure a minimum healthy air circulation
  • No damage by fire, leaked water, foam or other extinguishing agents. Retaining access to protected areas at any time
  • No environmental impact
  • Easy to install and maintain
  • The system functionality can be verified at any time in real time.



  1. 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%).
  2. The entire room of the data center is ventilated with hypoxic air, inhibiting fire ignition.
  3. Low oxygen air leaks from the room, thus completing the flow of air and ventilating the space.
  4. A control unit monitoring the room with oxygen-sensors permanently ensures a stable and healthy low oxygen environment in the room.

*Calculated for air exchange (leakage taken in 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 protected area, two, three or more systems shall be used.
