Fire Suppression Systems

Name: Clean Agent Fire Suppression Systems
Brand: Wira Fire

Total flooding clean agent systems for rooms where water would destroy what it is meant to protect. FM-200 or Novec 1230, in an engineered pipe network or a self-contained cabinet, from 40 to 180 litres.

Bank of three red clean agent suppression cylinders manifolded together in a steel frame

What we supply

Engineered pipe-network systemsCylinders manifolded together and piped to nozzles across one or several protected zones. 4.2 MPa storage, 40 to 180 litres.

Cabinet systemsSelf-contained unit standing in the room it protects. No pipe network, no builder’s work. 2.5 MPa storage, 40 to 180 litres.

Both agentsFM-200 (HFC-227ea) and Novec 1230 in the same hardware — zero ozone depletion, electrically non-conductive, no residue to clean up.

Detection and releasingSmoke and heat detection, releasing control panel, discharge indicator, manual release and abort, alarm bell and sounder-beacon.

Design and commissioningHazard assessment, agent quantity calculation, pipe and nozzle layout, installation, functional testing and handover documentation.

Systems are designed to NFPA 2001, the standard for clean agent fire extinguishing systems. Agent quantity depends on the room volume, its minimum temperature and how well it is sealed — send us the room and we will size it.

Engineered pipe-network system

For larger rooms, several rooms from one cylinder bank, or where the cylinders must stand outside the protected space.

Maximum agent charge is the cylinder volume at the filling rate below; the design quantity for your room will usually be less.

Cabinet system

Everything in one enclosure — cylinder, valve, nozzle and controls — standing inside the room it protects. Suited to a single server room, switchroom or store where running pipework is not worth the disruption.

Release is normally interlocked to cross-zoned detection — two independent detectors must operate before the agent is released — with a manual abort inside the protected room. We set the discharge delay to suit the evacuation time for the space.

Typical applications

Clean agent is for rooms where a sprinkler discharge would cause more loss than the fire. Where water is acceptable, it is usually the cheaper and simpler answer — we will say so.
