FIRE SUPRESSION SYSTEM

Gaseous fire suppression

Gaseous fire suppression is a term to describe the use of inert gases and chemical agents to extinguish a fire. The system typically consists of the agent, agent storage containers, agent release valves, fire detectors, fire detection system (wiring control panel, actuation signalling), agent delivery piping, and agent dispersion nozzles. Less typically, the agent may be delivered by means of solid propellant gas generators that produce either inert or chemically active gas.

Carbon dioxide piped systems

Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. Carbon dioxide has also been widely used as an extinguishing agent in fixed fire protection systems for local application of specific hazards and total flooding of a protected space.


Inergen piped and modular systems

Inergen is a blend of inert atmospheric gases that contains 52% nitrogen, 40% argon, 8% carbon dioxide. It is considered a clean agent for use in gaseous fire suppression applications. Inergen does not contain halocarbons, and has no ozone depletion potential. It is non-toxic. Inergen is used at design concentrations of 35-50% to lower the concentration of oxygen to a point that cannot support combustion, but still safe for humans.

FM200 piped and modular systems

FM 200 (HFC-227 or HFC-227ea) is a colourless, odourless gaseous
halocarbon commonly used as a gaseous fire suppression agent HFC-227ea finds use in fire suppression systems in data processing and telecommunication facilities, and in protection of many flammable liquids and gases. 


Aerosol fire suppression

Aerosol fire suppression generators provide highly effective, environmentally friendly fire suppression for fires in enclosed facilities and local spaces. Aerosol generators are virtually maintenance free. Upon activation, the generators produce an exceptionally effective, ultra-fine, potassium based aerosol.


Novec 1230 piped systems

Novec 1230 is an environmentally friendly Halon replacement for use as a gaseous fire suppression where water from a fire sprinkler would damage expensive equipment or where water based fire protection is impractical, such as banks, clean rooms and hospitals.
The product is ideal for use in total flooding applications and may be used in portable extinguishers for specialised application

Room integrity testing

To ensure the effectiveness of your gaseous fire suppression system, the ‘integrity’ of the room, i.e. its capacity to hold the gas is a critical factor. Room integrity testing is vital to ensure your protected area is well sealed and your gaseous agent won’t escape causing the fire to possibly re-ignite.
