Enhanced Fire Suppression for Larger 3D Printer Enclosures
The BlazeCut TR045FK-PRUSA is a self-contained automatic fire suppression unit designed for larger 3D printer enclosures, including extended builds and multi-printer setups. Purpose-built for compact electrical environments, this unit is ideal for protecting Prusa models and other desktop 3D printers operating inside enclosed spaces where heat and unattended print jobs increase fire risk.
The system consists of a black, abrasion-resistant heat-sensitive tube filled with FK-5-1-12, a Clean Fire Suppressing Agent. Once temperatures inside the enclosure reach approximately 267°F (±6°F), the tube melts at the hottest point, forming a nozzle and instantly releasing the agent onto the fire source. It suppresses flames fast—without water, foam, or powder—and won’t damage electronics or create cleanup issues.
With increased protected volume over the TR032FK-PRUSA, this model is ideal for larger Prusa enclosures, dual printer racks, or enclosures containing multiple power supplies, heated beds, or filament dryers.
🔒 This model does not include a pressure switch. For advanced features like alarm signaling or system-triggered shutdowns, see BlazeCut “-S” models (e.g., TR050FK-S).
