Gaseous Suppression Systems

Gaseous suppression is a term used to describe the suppression of fire using specialised gas. This kind of suppression system is required in closed areas where water sprinklers can not be used, such as in archive rooms, server/data centres museums clean rooms. Gaseous suppression system can be set to be automatic or manual as per user preference.

The system consists of the control panel, the detection equipment and the agent storage cylinder. In that way when the detectors, such as smoke or heat detectors, detect smoke or heat, the first stage of alarm is triggered informing the user to take action on the control panel. The user can manually release the agent to be discharged or cancel the discharge process if he decides that is a false alarm. If no action is taken and the second zone of detection is triggered then the agent is discharged automatically.

There are mainly two categories of clean agents: the chemical agent and the inert gas range. Using a different principle, both agents can achieve the suppression of a fire condition in a closed area.

Importantly Clean agents are:

  • Safe to be used in human occupied areas
  • Environmentally Safe
  • Safe to Electronic Equipment
  • Leave no residue after discharge

KEEPER Security has more than 20 years of fire suppression installation and maintenance experience. We are able to offer all the different types of chemical and inert range gasses in industrial, commercial and special hazard applications.

Chemical Agents

Available fluids for suppression: NOVEC 1230 and FM200

They are stored in liquid form in low-pressure cylinders of 25-42 BAR and become gas when the discharge takes place.

Clean Agent systems extinguish a fire quickly removing the heat by breaking down the molecular structure of the fire.

Major advantages of chemical agents:

  • They do not harm the equipment or personnel in the protected room
  • They offer rapid fire extinguishment, suppressing fires within seconds of the agent being discharged into the protected area  
  • Are ventilated out of the space and do not leave behind a residue to be cleaned up, allowing your facility to get back to work immediately
  • They are non-toxic and do not impair breathing or obscure vision in an emergency situation, providing an added measure of safety for personnel

Inert Range

Available gases for suppression Argonite, IG55, Inergen.

Inert range gases are clean naturally occurring gases found in the environment such as Argon and Nitrogen. They are stored in gas form in high-pressure cylinders of 200 and 300 Bars

They extinguish a fire by reducing the oxygen content within a room to the point at which fire can no longer burn, but without compromising the safety of individuals present.

Major advantages of inert range agents:

  • Safe
  • The system has no direct global warming or ozone depletion potential
  • It has minimal post-fire clean-up
  • It will not decompose or produce any by-products when exposed to a flame from a fire situation.
