Oxygen reduction system for the Data Center - part 2

 1-Sealing of the space:

• the room or space which is being protected needs to be as well sealed as possible. 
• A better sealed room means smaller equipment and therefore lower running costs.
• Space must have split-type air conditioning systems or closed dedicated recirculating air conditioning systems
• If continuous access is provided, the use of double door systems or curtains is recommended.

3. Generators technology:

• Membrane Technology:

pressurised ambient air is pressed through a bundle of polymer fibres. These fibres separate the nitrogen and oxygen molecules: oxygen molecules diffuse through the fibre walls, whereas the larger nitrogen molecules flow past the fibres. A network of pipes directs the extracted nitrogen into the protected area. The membrane method of separating nitrogen and oxygen molecules provides a continuous flow rate.

• Activated carbon:

With activated carbon, the oxygen and nitrogen molecules in the air are separated from one another using carbon molecular sieves (CMS). The air is compressed to a slight overpressure level of 1-2 bar (VPSA model) / 6-8 bar (PSA model), then pressed through the CMS bed (filter) into two identical containers.
