TBDR-FR - Fire Rated Plenum Slot Return

The TBDR-FR Fire Rated Plenum Slot Return is a critical component for maintaining fire safety in HVAC systems. Designed by Titus, this diffuser excels in preventing the spread of fire and smoke through ceiling plenums. Constructed from durable steel, it undergoes rigorous testing to meet UL time-temperature criteria and NFPA 90A requirements, ensuring a reliable fire barrier for up to 3 hours. The inclusion of a light baffle further enhances safety by blocking light transmission and preventing visibility into the ceiling plenum.

This fire-rated return unit stands out with its blend of safety and performance. It's engineered to provide the same efficient return airflow as the supply diffuser, ensuring optimal HVAC system performance. Key features include a damper equipped with a 212° F fuse link for automatic closure in the event of a fire and a choice of 3/4”, 1” or 11/2” slot widths with 1 or 2 parallel slots. The TBDR-FR is available in 24”, 36”, and 48” nominal lengths to accommodate various project requirements.

The TBDR-FR Fire Rated Plenum Slot Return is ideally suited for projects with exposed grid, suspended ceilings where fire safety is paramount. This makes it a common choice for commercial buildings, healthcare facilities, educational institutions, and other applications where building codes mandate fire-rated construction and efficient air distribution. Classified under Masterformat Division 23 37 13 for Diffusers, Registers, and Grilles, the TBDR-FR offers peace of mind and reliable performance for demanding HVAC installations.
