Automatic Fire Suppression for Small Enclosures — No Power, No Mess, No Worries

The BlazeCut T Series R with FK-5-1-12 is a compact, fully self-contained fire suppression system designed to protect enclosed or semi-enclosed spaces where fire risk is high and traditional systems don’t fit. This system requires no external power source and functions completely automatically—activating the moment rising heat signals danger.

Inside the abrasion-resistant black detection tube is a powerful Clean Fire Suppressing Agent (FK-5-1-12). When temperatures inside the protected space reach approximately 267°F (±6°F), the tube melts at the hottest point, triggering immediate discharge of the agent directly onto the source of the fire. The result: fast, targeted suppression with no residue, no cleanup, and no collateral damage.

Ideal For:

  • 3D Printer Enclosures – Desktop and hobbyist enclosures (including Prusa-style builds)

  • Electronics Cabinets – Small fuse boxes, distribution panels, and compact electrical enclosures

  • Battery Storage – Enclosed lithium-ion or lead-acid battery compartments

  • AV & Network Gear – Home AV racks, compact server cases, and network switch enclosures

  • ATM & Kiosk Units – Self-contained kiosks and automated systems with confined internal electronics

  • Other Micro-Enclosures – Any tightly enclosed space under 3.5 cubic feet with high fire risk and limited ventilation

Key Benefits:

  • Automatic Activation – No need for wiring or external triggers

  • Clean Fire Suppressing Agent (FK-5-1-12) – Safe for electronics, people, and the planet

  • Environmentally Responsible – Zero ozone depletion, low global warming impact

  • Compact & Self-Contained – Installs directly inside the space it protects

  • Integrated Pressure Gauge – Easily confirm system status at a glance

  • Simple DIY Installation – Includes zip ties; horizontal mounting recommended

  • No Maintenance Required – Long service life, up to 10 years

What Makes FK-5-1-12 Different?

FK-5-1-12 is a non-toxic, non-conductive, and residue-free clean agent that’s safe for people, equipment, and enclosed spaces. It’s also one of the most environmentally friendly fire suppressants available, with zero ozone depletion potential and a very low global warming potential—making it a smarter, safer alternative to traditional halon-based agents.

Frequently asked questions

How does BlazeCut work?

BlazeCut uses a heat-sensitive tube containing extinguishing agent. When exposed to high temperatures, the tube melts and releases the agent to suppress the fire automatically.

Where can BlazeCut be installed?

Common installation sites include engine compartments, electrical cabinets, data centers, and enclosed spaces at risk of fire; it’s important to check specific product volume recommendations for each enclosure.

What types of fires does BlazeCut suppress?

BlazeCut is effective on electrical, liquid, and solid fuel fires, particularly in small closed spaces.

What is the lifespan/shelf life of a BlazeCut system?

The tube and system can last between 5 and 10 years, depending on environment and application.

Does BlazeCut leave behind residue or damage equipment?

BlazeCut uses clean agents which do not conduct electricity, corrode, or damage electronics, and are safe for people in typical application volumes.
