What is Pyrogen?
Pyrotechnically Generated
Aerosol Fire Extinguishing System
Evolution:
The Secret to Pyrogen’s Power
• Unique formulation of
– solid aerosol generating
composition ~ derivative of
solid rocket fuel
– solid chemical coolant ~
ensures flameless operation &
rapid expulsion
• Produces gas-like fire fighting
aerosol with 3 dimensional
distribution when ignited
Technical Characteristics:
Four Main Elements
Directional Plate
Chemical Coolant
Solid Block of Aerosol
Generating Composition
Electric Ignition Device
Technical Characteristics:
Multiple Activation for Ignition
• Electrical
– Automatic via detection system or,
– Manual via manual release point
• Thermal
– Automatic via temperature sensitive pyrotechnic
cord 175 C (347 F)
Technical
PRODUCTCharacteristics:
DESCRIPTION:
Aerosol Generation
Ignition of aerosol-forming composition =
solid potassium carbonates + carbon
dioxide gas + nitrogen gas + water vapor
KNO3(s) + CnHmNpOq(s) + C(s) =
KHCO3(s) + K2CO3(s) + CO2(g) + N2(g) + H2O(g)
Technical Characteristics:
Chemical Coolant
• Polymer composition highly impregnated with
endothermic ingredients
– Substances that decomposes at 200-300°C (392572F) without melting, generating gases and
absorbing approximately 400 calories of heat per
one kilogram of their mass.
– Cooling is effected at a fantastic rate of 400° per
second

BENEFITS:Characteristics:
Micron Size Aerosol Particles
• Large surface area for extinguishing actions
• Small amount required for reliable
extinguishing
• Gas-like 3 dimensional distribution
• Long suspension times

How It Works:
Aerosol Generated
Chemical coolant decomposes absorbing heat
Fire fighting aerosol rapidly generated
How It Works:

How It Works:
Extinguishing Actions
• Dual Extinguishing Actions
– Primary:
• Chemical
- Removal of chain carriers
– Secondary:
• Physical
- Heat absorption
How
It Works:
BENEFITS:
Dual Extinguishing Actions
• Chemical - removal of chain carriers OH, H and O
– in gaseous phase:
• K + OH = KOH
• K + O = KO
• KOH + H = K + H2O
– on particles surface:
• O + H = OH
• H + OH = H2O
• Physical - heat absorption
• KHCO3 = K2CO3 + CO2+ H2O
• K2CO3(s) = K2CO3(g)
How
It Works:
BENEFITS:
Extinguishing Actions
• Two Chemical Mechanisms
– Removal of flame propagation radicals - chain
carriers OH, H and O in the flame chain
K + OH = KOH
KOH + H = K + H2O
– Recombination of flame propagation radicals chain carriers OH, H and O aerosol on particles
surface:
O + H = OH
H + OH = H2O
How
It Works:
BENEFITS:
Extinguishing Actions
• Physical - Lowering the fire temperature to a level
below which the fire reaction cannot continue
thermal cooling
– Heat absorption via endothermic phase changes
K2CO3(s) = K2CO3(l) = K2CO3(g)
– Heat absorption via endothermic decomposition changes
2KHCO3(s) = K2CO3(S) + CO2(G) + H2O(g)
How
It Works:
BENEFITS:
Extinguishing Actions
• Physical - Lowering the fire temperature to a level
below which the fire reaction cannot continue
thermal cooling
– Dilution of the fire combustion zone by the aerosol cloud
(additional fuel molecules cannot participate in the
combustion process)
– Physical hindrance to flame propagation
(aerosol particles slow down velocity of a flame front
propagation)
