BlazeCut TR400FK Auto, RV, Boat - Automatic Fire System, Tubular Fire suppression for vehicles, engine compartments, generators, and other enclosed space fire risks.
High-Capacity Fire Suppression for Large Enclosures and Demanding Applications
A fire in a large enclosed compartment can escalate quickly and cause major damage before anyone has time to respond.
The BlazeCut TR400FK is built for large enclosed spaces where heat can build fast and the cost of a fire can be high.
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 equipment, controls, or engine components.
And in many cases, the real risk is bigger than the compartment itself. A fire that starts in one enclosed area can spread to the rest of the vehicle, vessel, equipment, or building if it is not controlled early. The TR400FK is designed to help control the fire at the source before it becomes a much larger loss.

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.
