1. Ignition Thresholds 

2.Two-Stage Oxygen Reduction :

3. Layout of Two-Stage Oxygen Reduction:

4. Advantages of the two-stage fire ­protection for data centres:

• Almost no energy costs in normal operation.
• No power shutdown necessary as there is no reignition.
• The drawback with traditional extinguisher , however, is that reignition cannot be effectively and reliably prevented, unless the power is disconnected
• Top reliability thanks to regular checking of the leak-tightness of the overall system.
• Highly effective fire suppression at all times.
• refilling N2 cylinder in site by N2 generator.
