Pyrogen EXA & EXA-M / Condensed aerosol fire suppression is a particle-based form of fire extinction similar to gaseous fire suppression or dry chemical fire extinction. The aerosol employs a fire extinguishing agent consisting of very fine solid particles and gaseous matter to extinguish fires. The condensed aerosol microparticles and effluent gases are generated by the exothermic reaction; until discharged from the device, the particles remain in vapor state. They are cooled and "condensed" within the device and discharged as solid particles.
Compared to gaseous suppressants, which emit only gas, and dry chemical suppression agents, which are powder-like particles of a large size (25–150 micrometres), condensed aerosols are defined by the National Fire Protection Association as releasing finely-divided solids of less than 10 micrometres in diameter. The solid particulates have a considerably smaller mass median aerodynamic diameter (MMAD) than those of dry chemical suppression agents, remain airborne significantly longer, and leave much less residue within the protected area. Whereas dry chemical systems must be directly aimed at the flame, condensed aerosols are flooding agents and therefore effective regardless of the location and height of the fire. Wet chemical systems, such as the kind generally found in foam extinguishers, must, similarly to dry chemical systems, be sprayed directionally onto the fire. The condensed aerosol agent can be delivered by means of mechanical operation, electric operation, or combined electro-mechanical operation.

Fire Suppression Mechanism
Pyrogen EXA & EXA-M / Condensed aerosol systems are suitable for special hazards applications as replacements for Halon 1301 systems and high-pressure carbon dioxide systems. Aerosol systems can also be used as alternatives to clean agent gaseous suppressants or water-mist systems.
Pyrogen EXA & EXA-M is ideal for:
- Electrical Substations
- Telecommunication Rooms
- Server Rooms
- Control Rooms
- Electrical Cabinets
- Marine Vehicles
- CNC Grinders
- Mining Vehicles
- Heavy Transport Vehicles
Advantages of EXA & EXA-M
- Fast response after detection of fire
- Rapid system discharge – instantaneous extinguishing action
- Low agent concentration
- No pressure cylinders
- No moving parts
- No gases or liquids, therefore no leakages
- No pipe work or manifold
- Simple to install & re-commission
- No maintenance required for aerosol modules. Only checks on electrical circuit required
Compact & Versatile
- Smallest & lightest fire extinguishing system
- Resistant to atmospheres with high humidity, corrosiveness and saltiness
- Flexible choice of operation modes – either automatic, manual, electrical, or thermal
- Can be fully autonomous stand-alone systems when coupled with our TAD detection and activation devices-no power source or battery required.
Tested & Certified
- Activfire, Active Fire Protection – Product Certification by CSIRO Australia
- Approved alternative to Halon under Significant New Alternatives Policy (SNAP) program by United States Environmental Agency (USEPA)

The United States Environmental Protection Agency has approved Pyrogen EXA & EXA-M / condensed aerosol fire suppression systems as acceptable substitutes for Halon 1301 in Total Flooding Systems. Pyrogen EXA & EXA-M / condensed aerosol fire suppression systems are also non-ozone depleting and carry little or no global warming potential.
