TELFORDS Facility Management Limited are the agents in Ireland and the United Kingdom for Isolcell's N2 FIREFIGHTER, an Oxygen Reduction System (ORS). Management at TELFORDS Facility Management have over 35 years experience in fire prevention systems.

The N2 FIREFIGHTER methodology prevents the development or spreading of open fires by adding nitrogen to the atmosphere.

The N2 FIREFIGHTER systems monitor, and through a natural filtration process, change the ratio of gases normally present in the air we breathe, thus creating a perpetually self-extinguishing atmosphere.

We are now able to create fully protected environments and to completely eliminate the fire hazard by changing the atmosphere within a building by allowing full access to people at the same time.

There are no chemicals or other artificial additives being added in this process so this prevention method is absolutely environmentally friendly and safe to human beings.

Oxygen depletion fire prevention systems are the perfect solution for fully or half automated warehouses, if it is an ambient temperature warehouse or a cold store, the method eliminates the risk of fire completely thus also eliminating consequential damages a fire would cause.


N2 FIREFIGHTER Oxygen Reduction System (ORS)


The perfect solution for:

  • Data Centres
  • Critical Rooms/Spaces where a fire must not occur under any circumstances.
  • Aviation Control Spaces.
  • Automated/Intensives Warehouses.
  • Storage of Hazardous Materials.
  • Freezing Warehouses.
  • Refrigerated Warehouses.
  • Food Warehouses.
  • Paper Mills.

The N2 FIREFIGHTER method, developed by Isolcell S.p.A., uses electric equipment to generate a reduced-oxygen atmosphere, using molecular separation. Its environmentally-friendly and energy-efficient process increases the nitrogen-to-oxygen ratio in the air to generate a reduced-oxygen atmosphere in which fires cannot start.

The generated and controlled atmosphere makes a fire impossible

For a fire to ignite three elements are needed: Heat, combustibles and an oxidizing agent, usually oxygen. When these elements are present and in the right mixture a natural fire will occur.

A fire can be prevented or extinguished by removing any one of these elements. Once a fire has started, the exothermic chain reaction sustains the fire and allows it to continue until or unless at least one of the elements of the fire is blocked. Traditional fire fighting methods either deny the burning fire the oxygen it needs or they lower the temperature of the fuel below the ignition point or by creating a barrier of inert gases thus attacking the chemical reaction responsible for the fire.

With the "N2 Firefighter" we actively prevent the combustion process to get started by uninterruptedly reducing the amount of oxygen.

  • Protected premises are safe 24/7/365.
  • The fire hazard is completely eliminated.
  • No consequential damages due to false alarm.
  • No consequential damages caused by historical extinguishing agents.
  • Prevention method is environmentally safe, non-toxic, non-polluting, non-residual.
  • Ease of installation and cost effective compared to standard extinguishing methods.
  • Due to N2 Firefighter technology no negative aesthetic impact to the building.
  • Easy protection even in areas difficult to reach or subject to strong regulation restrains.
  • Can easily be integrated with main fire panel or building management systems.
  • N2 Firefighter is maintenance friendly.
  • No additional space required for tanks, gas cylinders etc.
  • Protective atmosphere slows down the degrading process of certain materials.
  • N2 Firefighter protects object of all sizes, from miniature to giant dimensions.


The N2 Firefighter Fire Prevention Method is safe to humans, The amount of oxygen available within the protected area is similar to the amount of oxygen provided by nature in higher altitudes.
