Gas Suppression Systems South Africa protect rooms where water would destroy what the fire has not: server rooms, switch rooms, control rooms and archives. The agent floods the space and puts the fire out without wetting anything. Send one request and compare quotes.

Get the Best QuoteAgent Types
- Chemical clean agents. FM-200 and Novec, low concentration, small cylinder footprint.
- Inert gases. Argon, nitrogen and blends, no breakdown products, more cylinders.
- CO2. Effective but hazardous to occupants, restricted to unoccupied spaces.
- Aerosol. Compact units for small enclosures and panels.
- Water mist. An alternative where a gas hold is impossible to achieve.
What a System Includes
- Cylinders and brackets. Sized by room volume and agent concentration.
- Discharge pipework and nozzles. Calculated to flood the space in seconds.
- Detection. Usually double-knock, two detectors before discharge.
- Control panel. Release logic, abort and manual release.
- Pressure relief. A vent so the discharge does not blow the walls out.
Ongoing Requirements
- Annual service. Cylinder weights, pressure, pipework and detection.
- Room integrity test. Proves the room still holds the agent long enough.
- Hydrostatic testing. Cylinders tested periodically to their rating.
- Refill after discharge. Including investigating why it discharged.

Get the Best QuoteWhat Affects the Price
- Room volume. The main driver, because agent quantity is calculated from it.
- Agent choice. Inert gases need more cylinders and more space to store them.
- Room sealing. A leaky room needs more agent, or sealing work first.
- Pressure relief. Often overlooked and frequently a significant extra.
- Detection integration. Double-knock detection and interfaces to the main panel.
- Cylinder location. Remote cylinder rooms mean longer pipe runs and bigger calculations.
What to Include in Your Request
- Room dimensions. Length, width and height, including the void above the ceiling.
- What is in it. Servers, switchgear, archives or process equipment.
- Is it occupied. This rules some agents in or out entirely.
- Existing detection. Panel make, and whether it can drive a release.
- Ceiling and floor voids. Protected volume usually includes them.
Where Systems Fail
- Seal the room. Cable penetrations left open let the agent out in seconds.
- Test the integrity. A room that held the agent at handover may not after a cabling job.
- Fit pressure relief. A sealed room with no vent risks structural damage on discharge.
- Brief the occupants. People need to know what the pre-discharge alarm means.
Gas Suppression Systems FAQs
Is clean agent safe for people in the room?
The common chemical and inert agents are designed to be used at concentrations safe for occupied spaces, with a pre-discharge delay to allow people out. CO2 is the exception and is restricted to unoccupied spaces.
How long does the agent hold?
The design normally requires the concentration to hold for a set period, which is what a room integrity test measures. A room that fails the test does not hold long enough to be effective.
What does a discharge cost to put right?
The refill is the largest part and can run to six figures on a bigger room, which is why investigating false discharges properly matters as much as the refill itself.
Do we still need extinguishers in the room?
Usually yes. Gas suppression handles a developed fire in the enclosure; portable units handle something small and local before it gets there.
Gas suppression is one of the systems quoted through Fire Safety Inspections South Africa and it depends on both detection and room sealing.
