FM200 Fire Suppression System

The  FM200 systems are based on many years experience in the design, supply, installation and commissioning of gaseous fire fighting systems. During this time Halons have provided industry and commerce with a unique and versatile extinguishant to respond to most fire protection needs. The Montereal Protocol presented the fire protection industry with a most demanding challenge – to find a replacement for Halons. Gielle evaluated a large number of candidate agents over several years before selecting FM200.

FM200 is a colourless gas which is liquified under pressure for storage. Like Halon 1301 it has a low toxicity level and is superpressurised with Nitrogen to 24.8bar (360psi). It rapidly extinguishes most commonly found fires through a combination of chemical and physical mechanisms.

CO2 Fire Suppression System

Benefits of CO2 Fire Suppression Systems:

  • Fast – Within seconds, CO2 penetrates the entire hazard areas to smother the combustion.
  • Environmentally Friendly – CO2 exists as a gas in the earth’s atmosphere and is one of the by-products of combustion. Its use has no environmental impact.
  • Non-damaging – CO2 does not cause spoilage, requires no clean up and leaves no residue.
  • Non-conductive – CO2 is electrically non-conductive, allowing use for a wide variety of special applications.
  • Adaptive – CO2 is effective on a wide range of flammable and combustible materials.

A CO2 fire suppression system consists of one or more banks of cylinder storage containers to supply the CO2 extinguishing agent. Flexible discharge hoses connect the cylinders into a piping manifold. The manifold distributes the agent into the piping network. Nozzles regulate the flow of CO2 into the protected area.

Carbon dioxide or CO2 is a colorless, odorless, electrically non-conductive gas that is highly efficient as a fire suppression agent. SKA  Carbon Dioxide fire protection systems use intelligent, reliable and fast-acting control panels to quickly sense a fire before it can cause damage to property. Carbon dioxide gas has a high rate of expansion, which allows a SKA CO2 fire protection system to work fast.

CO2: A Low-Cost, Non-Damaging, Non-Conductive, Multi-Hazard Protectant

  • Low and High-Pressure options – meets requirements for large quantities of CO2 or fits small-space requirements
  • Fast – Smothers fire within seconds
  • Environmental – as clean as safe as the air we breathe
  • Non-Damaging – no residue, no spoilage, no cleanup
  • Non-Conductive – works in applications where water won’t
  • Adaptive – extinguishes virtually every type of combustible material

Inert Gas Fire Suppression

Concept Fire Suppression’s IG55 Inert Gas Fire Suppression Agent is a standard 50:50 mix of two inert gases Nitrogen and Argon. Both gases occur naturally in the atmosphere and are therefore the ultimate in an environmentally safe fire suppression product that is also safe for people. They have a Global Warming Potential and Ozone Depleting Potential of zero and does not decompose on application to a flaming fire.

Design and Operation

As inert fire suppression systems are stored as gas it makes them very flexible allowing us to design systems with multiple banks of cylinders protecting multiple enclosures. This negates the need for individual banks of cylinders for each enclosure. Using directional valves multiple rooms can be piped back to a central bank of cylinders and when a detector detects a fire the correct valve is operated and the gas will be discharged into the correct enclosure. Also cylinders can be stored away from the protected enclosure within a plant room or storage area thereby making more efficient use of operational space(see below).

Hardware

ProInert Inert Gas Fire Suppression Cylinders

 As manufacturers can only differentiate on hardware, as the agent is basically the same they have come up with a few simple and sometimes very innovative ideas to differentiate the products.

The original way to reduce the pressure from 200 or 300 bar to around 45 bar is to use an orifice plate, which basically looks like a large washer. It works on the principle that by restricting the flow through the pipework when the gas gets past the orifice plate and into a larger pipe, the pressure is reduced. This works well but the pipework between the cylinder and the orifice plate needs to be designed to operate at much higher pressures than the pipework after the plate.

Room Integrity Testing

To ensure that the gas is contained in the enclosure for as long as possible (BS EN 15004 stipulates a minimum of 10 minutes) the room needs to be pressure tested. This test checks that the enclosure is sufficiently sealed, that it will maintain the concentration levels required to suppress the fire for the minimum time period. This can only be carried out at the end of the installation or project after the room has been completed and all holes and entry points through the walls, floor and ceiling have been sealed using fire proof materials.

IG-55 (Argonite)

IG-55 (Argonite) is an inert gas comprising of 50% Argon & 50& Nitrogen, it is naturally present in the atmosphere, therefore its green- house effect is nil and its ozone layer depletion potential is zero.

The DIMES sensor units is integrated into a special valve with an linear electrode. This replaces the standard system valve.
The built-in sensors monitor ambient temperature and the capacitance differential of the gas density between two electrodes
in the dip tube.
An integrated microchip calculates the exact cylinder contents based on the known densities of CO2 gas at different ambient temperatures. You input the cylinder volume and 100% fill level during a simple one-time configuration when the cylinder is
filled.
If the contents would ever fall below a pre-set level, such as in the event of a leak, a warning signal will sound via the control box. A warning signal is also sent when the system discharges.
