Introduction
- 1 Evolution of Pyrogen
- 2 Technical Characteristics
- 3 Performance and Benefits
- 4 Typical Applications Installations
- 5 Comparison with Other Gases
3What is Pyrogen?
Evolution
- Pyrotechnically Generated
- Aerosol Fire Extinguishing System
4From Rocket Fuel to Revolutionary Fire
Extinguisher
Evolution
- Highly effective fire suppression system
Advanced product of Russian space technology - Conversion of military research into civil
applications
5The Secret to Pyrogens Power
Evolution
- 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
6Four Main Elements

Chemical Coolant
Solid Block of Aerosol Generating Composition
Electric Ignition Device
7Multiple Activation for Ignition
Technical Characteristics
- Electrical
- Automatic via detection system or,
- Manual via manual release point
- Thermal
- Automatic via temperature sensitive pyrotechnic
cord 175 C (347 F)
8Aerosol Generation
PRODUCT DESCRIPTION
Technical Characteristics
- 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)
9Chemical Coolant
Technical Characteristics
- Polymer composition highly impregnated with
endothermic ingredients - Substances that decomposes at 200-300C
(392-572F) 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
10Micron Size Aerosol Particles
Technical Characteristics
BENEFITS
- Large surface area for extinguishing actions
- Small amount required for reliable extinguishing
- Gas-like 3 dimensional distribution
- Long suspension times

17Extinguishing Actions
How It Works
- Dual Extinguishing Actions
- Primary
- Chemical - Removal of chain carriers
- Secondary
- Physical - Heat absorption
18Dual Extinguishing Actions
How It Works
BENEFITS
- 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)
19Extinguishing Actions
How It Works
BENEFITS
- 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
20Extinguishing Actions
How It Works
BENEFITS
- 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)
21Extinguishing Actions
How It Works
BENEFITS
- 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)
