Heavy-Duty Fire Suppression for Demanding Enclosures and High-Risk Equipment A fire in a large enclosed compartment can spread fast and cause major damage before anyone can respond. The BlazeCut TR300FK is built for larger enclosed spaces where heat builds quickly and fire risk is higher. It mounts inside the space you want to protect and works automatically.There’s no wiring, no external power, and no complicated setup. If the temperature gets high enough, the tube opens at the hottest point and releases FK-5-1-12 clean agent directly onto the source of the fire. That gives you fast suppression where the fire starts, without powder residue covering your equipment, controls, or engine components. And in many cases, the biggest risk is not just the compartment itself. A fire that starts in one enclosed area can spread to the rest of the vehicle, vessel, machine, or building if it is not controlled early. The TR300FK is designed to help control the fire at the source before it becomes a much bigger loss. Common uses Large marine engine bays (boats, yachts, commercial watercraft) Heavy-duty vehicle compartments (fire trucks, armored transport, shuttle buses, large RVs) Industrial machinery enclosures (packaging machines, conveyors, robotic systems) Electrical control enclosures (high-density cabinets, UPS systems, generator housings) Mobile power equipment enclosures (large battery compartments, backup systems, off-grid enclosures) Specialty vehicle enclosures (ag equipment, mobile command units, refrigerated trailers) Why people choose the TR300FK Activates automatically when heat reaches a dangerous level No power or wiring required Clean agent discharge (no powder mess) Safe for electronics Easy to install in enclosed spaces Built-in pressure gauge for quick status checks Up to 10-year service life If you want simple automatic fire protection in a large enclosed compartment with concentrated heat and fire risk, the TR300FK is a practical way to add protection before a small fire becomes a much bigger problem. Protection Specs: Application Type Protected Volume Electrical Enclosures 36.4 – 54.4 ft³ (1.03 – 1.54 m³) Engine/Fuel Compartments 27.2 – 41.0 ft³ (0.77 – 1.16 m³) Technical Details: Unit Length: 118.1 inches Operating Temperature: -4°F to +194°F Activation Temperature: 267°F ± 6°F 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.
