APC’s NetShelter AV enclosures and accessories are designed with features dedicated to meet the specific needs of the professional AV industry. New features in the NetShelter AV Enclosures emphasize the importance of flexibility for the ever-changing AV environments, with additions such as cable access roof with conduit knockouts and easily adjustable threaded rails. The NetShelter AV Enclosures feature pre-installed vertical zero-U accessory channels in the rear of the enclosure that allow users to mount busbars without tools, rack power distribution units, and cable management accessories. Each enclosure has pre-installed leveling feet and castors, and integrated baying brackets into the frame for easy positioning in a row. To address the ever-increasing equipment heat loads, APC introduces cooling accessories to improve ventilation and keep equipment running cool. Horizontal-mount fans featuring optional thermal controls offer assisted ventilation in tight spaces. Roof-mount fans and rear-mount, variable-speed fan doors provide a higher level of thermal assistance for larger applications. Closet level cooling units are also available for addressing thermal issues for the entire room.
