High-Capacity Fire Suppression for Larger Enclosures and Demanding Applications A fire in an engine bay, battery compartment, or electrical cabinet can get serious fast. The BlazeCut TR100FK is made for enclosed spaces where heat builds quickly and a small fire can turn into major damage before you can respond. It mounts inside the space you want to protect and works automatically 24/7.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 at the point of origin, without powder residue all over your engine bay, equipment, or electronics. Just as important, many of these spaces are part of something much bigger. A fire that starts in an engine compartment, battery bay, or control cabinet can spread to the rest of the vehicle, boat, equipment, or building if nothing stops it early. The TR100FK is designed to help control the fire where it starts. Common uses Marine engine compartments (small boats, personal watercraft, inboard bays) Vehicle engine bays (trucks, vans, SUVs, classic cars, performance builds) Electrical equipment and breaker panels Battery compartments (off-grid, solar, EV conversions, golf carts) Mobile equipment and compact generators Industrial control cabinets and enclosures Why people choose the TR100FK 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 or semi-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 space with concentrated heat and risk, the TR100FK is a practical way to add protection before a small fire becomes a much bigger problem. Protection Specs: Application Type Protected Volume Electrical Enclosures 12.4 – 18.4 ft³ (0.35 – 0.52 m³) Engine/Fuel Compartments 9.2 – 13.8 ft³ (0.26 – 0.39 m³) Technical Details: Unit Length: 39.4 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.
