Versatile Fire Protection for Critical Small-to-Midsize Enclosures A fire in a small enclosure can go from “nothing” to serious damage fast. That’s exactly why the BlazeCut TR050FK exists. It’s built for tight spaces like printer enclosures, battery compartments, and electrical cabinets where heat can build quickly and a small fire can turn into a costly loss before you have time to react. It mounts inside the space you want to protect and stays on guard 24/7.There’s no wiring, no external power, and no complicated setup. When the temperature reaches a critical point, the tube opens at the hottest spot and releases FK-5-1-12 clean agent directly onto the source of the fire. That means fast suppression where the fire starts, with no powder residue and no mess spread through your equipment. And for most people, that’s the bigger point. These enclosures are often sitting inside a home, garage, workshop, office, or equipment room. If a fire starts inside one and there’s nothing there to control it, it may not stay contained for long. The TR050FK helps address the fire at the source before it has the chance to spread to the surrounding area. Common uses 3D printer enclosures Small electrical cabinets and fuse boxes Battery compartments AV / network cabinets ATM and kiosk electronics compartments Other compact enclosed or semi-enclosed spaces with elevated fire risk Why people choose the TR050FK Automatic response when heat reaches a dangerous level No power or wiring required Clean agent discharge (no powder mess to clean up) Safe for electronics Easy to install in compact spaces Built-in pressure gauge for quick status checks Long service life (up to 10 years) If you have a compact enclosure with electronics or batteries inside, the TR050FK is a simple way to add protection where fires often start and help reduce the risk of that fire spreading to the space around it. Protection Specs: Application Type Protected Volume Electrical Enclosures 5.3 – 8.1 ft³ (0.15 – 0.23 m³) Engine/Fuel Compartments 3.9 – 6.0 ft³ (0.11 – 0.17 m³) Technical Details: Unit Length: 19.7 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.
