Aisle Containment System keeps hot and cool air separated for better temperature control and equipment performance in hot aisle/cold aisle configurations. FeaturesIndividual Roof Panel Designed for Standard-Width 600 mm Server RacksThis SmartRack® roof panel fills the gap between the Tripp Lite aisle containment system's telescopic beams (SRCTMTTLBM, sold separately). It helps you freely populate a hot or cold aisle with server racks of different sizes, while still providing a thermally enclosed space. The clear acrylic panel lets light shine through, saving you the time and expense of installing additional lighting. Pre-drilled holes allow easy installation using the included hardware with easy modification if needed. Filler panels attach magnetically to fill the open space between the rack cabinet and the containment frame's upper support beam. Rubber gaskets provide a tight seal that improves thermal efficiency in your rack cooling system.Tripp Lite's Aisle Containment System Manages Airflow for More Cooling EfficiencyUpon installation in your data center or server room, the modular, easy-to-assemble Aisle Containment System contains the air in a hot aisle or cold aisle, essentially creating a room within the aisle, while still keeping the aisle accessible. No costly contractor or HVAC specialist is required to install the system, which can be expanded or adapted to meet your needs. Assorted frame kits, beam kits, sliding double-door kits, roof panel kits and adapter riser panel kits (all sold separately) are necessary to assemble a hot or cold Aisle Containment System that accommodates the dimensions of your aisle and the rack enclosures within it.
