Blazecut TR025FK Automatic Fire Suppression - T Series (Black Tube) 

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

A fire in a small enclosure can go from “nothing” to serious damage fast.

That’s exactly why the BlazeCut TR025FK 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 small enclosures are often sitting inside a home, garage, workshop, office, or building. If a fire starts inside one and there’s nothing there to control it, it may not stay contained for long.

The TR025FK helps address the fire at the source, before it has the chance to spread to the surrounding area.

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.
