Low pressure clean agent systems store fire suppressants such as FM-200 (HFC-227ea) or Novec 1230 in cylinders as liquids under moderate pressure (25–50 bar). On activation, the agent rapidly vaporises and floods the protected space, extinguishing the fire within seconds by absorbing heat and, in the case of Novec 1230, also interfering with the chemical chain reaction of combustion.

FM-200 (HFC-227ea) is currently SANS 14520 compliant and remains widely used across South Africa. While its global warming potential (GWP of 3,220) has drawn some regulatory scrutiny internationally, it is not scheduled for phase-out in South Africa in the near term. Morimi Fire Solutions recommends Novec 1230 for clients seeking a longer-term, lower-GWP solution, particularly those targeting Green Star or LEED certification.

Novec 1230 has a global warming potential of just 1, compared to 3,220 for FM-200, making it the most environmentally sustainable clean agent currently available. It typically suppresses at a slightly lower concentration than FM-200, which can mean fewer cylinders. Both are equally effective at protecting sensitive electronics and are safe for occupied spaces at design concentrations.

System cost depends on the protected volume, number of nozzles, pipe network complexity, and whether a new or existing detection system is being integrated.

For a standard server room or telecoms room of 50–150 m², installation typically takes 5–8 working days. Larger data centre installations may require 2–4 weeks depending on the number of protected zones. All work is completed with minimal disruption to ongoing operations.
