Automatic Miniature Fire Suppression System (AMFSS)
Compact, convenient, and proven 24/7 standalone fire protection for electrical enclosures, server cabinets, CNC machines, and enclosed machinery. Powered by clean NOVEC 1230 / FK-5-1-12 gas suppression.
Compact First-Response Suppression
Designed to extinguish micro-environment fires directly at the source before catastrophic business interruption occurs.
Clean Agent NOVEC 1230
Utilizes NOVEC 1230 / FK-5-1-12 pressurized with Nitrogen at 60 bar. Safe around humans with NOAEL 10% rating, non-conductive, and leaves zero residue.
Thermo Bulb Trigger
German-manufactured glass ampoule ruptures at pre-selected temperatures (68°C, 79°C, 93°C, or 141°C) to instantly release suppression gas.
Flexible Configurations
Available in Standard AMFSS, S-AMFSS (remote monitoring pressure switch), and R-AMFSS (electrical/remote activation panel compatibility).
How the AMFSS System Activates
Rapid thermal detection and mechanical displacement guarantee activation without relying on external electrical power.
Thermal Rupture
An increase in temperature causes the precision thermo glass ampoule (bulb) to rupture at its set threshold.
Disc Rupture & Release
The spring-tensioned plunger ruptures the cylinder disc, allowing the immediate release of the fire suppression agent.
Head Assembly Travel
The fire suppression agent travels under 60-bar nitrogen pressure through the cylinder opening directly into the brass head assembly.
Enclosure Discharge
The fire suppression agent exits the head assembly through pre-drilled radial holes, expanding into gas to suppress fire throughout the protected space.
Engineered Components & Accessories
Heavy-duty brass head assemblies, pressure monitoring switches, and modular mounting hardware built for demanding environments.
Steel Cylinder & Brass Head
Pressurized 60-bar cylinder housing NOVEC 1230 clean suppression gas.
Nozzle Discharge Ports
Pre-drilled radial ports for uniform 360-degree gas distribution.
WIKA Pressure Switch
Optional CE/UL rated 60-bar stainless switch for alarm signalling & shutdown.
Cabinet Mounting Kits
Includes heavy-duty P-clips, 17mm nuts/bolts, and cable glands for clean cabinet pass-through.

Which System Do You Need?
Consider these key parameters when planning your AMFSS installation:
- Enclosure Volume: Calculate internal cubic volume of electrical cabinet or machine space.
- Sealing & Airflow: Check if risk area is airtight to prevent gas loss during discharge.
- Temperature Profile: Determine normal ambient vs peak operating temperatures to select bulb rating.
- Monitoring Integration: Confirm if automatic machine shutdown or external alarm switch is required.
