Hypoxic Air Fire Suppression Systems

• No fires - EVER!
• No Business Interruption.
• No extinguishing damage.
• Total protection of your buildings, contents and people.
• Protection against many acts of terrorism.
• No down time - always effective, even in the most hard to reach places
• No need for Over Pressure Compensation
• Reduced deterioration of stored items due to reduced oxidative corrosion

A revolutionary concept, that exploits the fact that ordinary air with a reduced oxygen content will not allow any normal material to burn.

OPERATION

• Hypoxic systems operate totally automatically under microprocessor control. Oxygen level in the protected space(s) is continuously monitored, and in most applications, the system will maintain the oxygen percentage between 14.5% and 15.5%.
• The system will deliver air with oxygen content of 10% (low enough to create a rapid change, but high enough not to be a threat to humans) until a level of 14.5% is sensed, when the system will shut down. With natural leakage and access events, oxygen level will gradually rise, until, at 15.5% the system will switch back on and inject air with 10% oxygen content, until 14.5% is again achieved.

DESIGN

• Total sealing is not required. The protected space must have some leakage to allow flushing to take place, but the leakage needs to be controlled. The smaller the leakage the smaller Hypoxic plant is required.
• Typical design target for leakage: 1% to 3% of the volume per hour. The lower the leakage, the lower the duty cycle and the lower the operating cost. No other sources of fresh air must be present. Ventilation must be re-circulatory. Any AC must be of the split system type.
• Air change in occupied space will be less than conventional practice.
• Where there is frequent access by people or vehicles some sort of air lock is helpful – such as a double door system or plastic walk/drive through curtain.
• In order to be effective it is necessary for there to be a boundary on the protected space.

UNIQUE DUAL FLOW™ SYSTEM

When the protected space is occupied, Hypoxic System can be programmed to operate in a different mode – delivering a constant flow of clean fresh air with oxygen content 15%. This provides air change for the occupants as well as removing odours and preventing any CO2 build up. Activation of Dual Flow can be fully automatic – operating only when people are present.
