Vertiv CPQ-893983-03 Active Fan Rear Doors | In-Row Cooling

Move heat out of the rack more directly with active fan rear doors built for Vertiv DCD35A801 and DCD35A0F environments. This 22-door set is intended for in-row cooling deployments where rear-side airflow assistance can help manage concentrated thermal loads without forcing a redesign of the room-level cooling strategy. Active rear-door cooling is a practical fit when rack density rises faster than the surrounding infrastructure. By adding fan-driven airflow at the rear of the enclosure, these doors help support heat extraction close to the source, reducing the burden on ambient room air and improving thermal control around high-load equipment. For teams planning phased capacity growth, this quantity supports multi-rack deployment consistency across a row or zone. It is a strong choice when you need a more controlled thermal path than passive airflow alone can provide, especially in environments where uptime depends on keeping inlet temperatures stable under changing load conditions. Use this configuration when you want targeted cooling support at the rack boundary, with the operational discipline expected in enterprise infrastructure rooms and data center rows.
