Mechanical Considerations 4.3 Airflow The server fans draw air into the equipment enclosure. After heated the air, the server fans force the air across the Liebert XDR’s two coils. The Liebert XDR has a low air-side pressure drop (similar to a rack with perforated doors). The server fans within the rack create sufficient airflow to move the air.
