Halocarbon clean agents — FK-5-1-12 (Novec 1230) and FM-200.
Fast-discharge, electrically non-conductive clean agents for sensitive electronic and electrical risks. Designed to NFPA 2001 and ISO 14520, sized to the room.
Heat absorption + radical inhibition
Halocarbon clean agents extinguish fire by absorbing heat (cooling) and through chemical chain-breaking. Discharge is rapid — typical 10-second design — and the agent is electrically non-conductive, leaves no residue and evaporates without any clean-up.
Discharge in 10 seconds
Rapid total flooding of the protected volume; design concentration achieved within the standard 10-second window.
Electrically non-conductive
Safe to discharge on energised electronics, server cabinets, switchgear and control panels.
No clean-up
Agent vapourises completely — no powder, no foam residue, no water damage to electronics.
