Gaseous Fire Suppression Systems

Gas fire suppression systems are innovative and can be uniquely designed to meet your building's requirements. These fire extinguishing systems are also sometimes called clean agent fire suppression as they use inert gases and chemical agents to extinguish a fire.

These systems are an effective way of dealing with electrical or Class B fires caused by chemicals and inflammable liquids. 

The main advantage of a gaseous fire suppression system is that the process is extremely quick and efficient in extinguishing the fire thereby minimising the potential damage to property and equipment.

These systems can be installed almost anywhere, but the most common environments where gaseous fire suppression systems are installed include:

  • Computer and IT server rooms
  • Museums
  • Telecommunication centres
  • Laboratories
  • Chemical and gas storage facilities
  • Places where valuables are stored.

We offer a range of chemical gas, inert gas and gas foam fire suppression systems, suitable for use in any environment.

You can rest assured we have exactly the fire suppression product to meet your needs, extinguishing fire without damage or corrosion to sensitive equipment and leaving the atmosphere safe for life.

Inert Gas Fire Suppression

They are highly effective fire suppression systems with no risk to electronic equipment, property or life. Inert gas systems extinguish fire mainly through reducing oxygen concentrations within the fire risk to the point where combustion is impossible, however levels of oxygen remain sufficient to sustain human life.

Excellent visibility is maintained during discharge, allowing efficient evacuation of the risk. Composed of naturally occurring gases, these inert gasses have no negative effects on the ozone layer or global warming.

Ideal for the protection of data centres, archives, museums, laboratories and any other hazard including valuable or unique property and any other electrical installation that may present a fire hazard.

CO2 Gas Fire Suppression

A CO2 system suppresses fire by providing a blanket of heavy gas that absorbs heat from the fire and reduces the oxygen content of the atmosphere to a point where combustion becomes impossible. This agent is suitable for both local applications as well as total flooding applications and its density is approximately 50% greater than the density of air.

CO2 occurs naturally in the atmosphere and dissipates into the air, allowing an almost immediate return to “business as usual” without the interruption of a costly clean-up and the expense of damage to assets from suppressant residue. This results in fewer repair costs and reduced downtime. CO2 has been used effectively for many years, not only in fire protection, but also in other commercial applications. The agent becomes white on initial contact with the environment and clears over time, becoming invisible.

Chemical Gas Fire Suppression

The main advantage of chemical gas fire suppression is the small amount of agent required to suppress a fire. Fewer cylinders are required resulting in one of the smallest footprints compared to most other fire suppressants.

No residue is produced, avoiding costly clean up. Zero ozone depletion potential means that these gases do not deplete stratospheric ozone, have minimal impact on the environment and also have an extremely low global warming potential.

Water Mist Fire Suppression

Spray heads discharge water mist at high pressure. The tiny drops create a large effective cooling surface area and the high speed of the droplets allows the mist to penetrate the hot fumes and reach the combustion area.

Once in contact with hot bodies and gases the droplets become a vapour, absorbing the heat and creating a smothering effect that protects any adjoining risks. If both the water vapour generated and temperature in the hazard is high enough, oxygen levels can fall drastically.
