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. Common uses Large marine engine compartments (yachts, offshore workboats, commercial vessels) Heavy-duty vehicle bays (buses, armored trucks, expedition rigs, overland builds) Large industrial panels and enclosures (power distribution units, server enclosures, MCCs) Backup power system enclosures (battery banks, solar storage containers, UPS enclosures) Specialized equipment enclosures (telecom shelters, HVAC control units, refrigeration trailers) Mobile infrastructure enclosures (field systems, emergency generators, mission-critical equipment) Why people choose the TR400FK 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 need automatic fire protection in a large enclosed compartment with concentrated heat and fire risk, the TR400FK is a practical way to add protection before a small fire becomes a much bigger problem. Protection Specs: Application Type Protected Volume Electrical Enclosures 48.4 – 72.0 ft³ (1.37 – 2.04 m³) Engine/Fuel Compartments 36.4 – 54.4 ft³ (1.03 – 1.54 m³) Technical Details: Unit Length: 157.5 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.
