Positive Pressurization and Ventilation - Hot Aisle Containment System (HACS)

Adequate airflow prevents equipment damage.

When installing the SL150 in an HACS environment, the system must maintain adequate air flow from the cold to hot aisle. Ensure that there is no turbulent air directed at the installed equipment which may reduce the cooling capability of the cold aisle supply air. The HACS pressure differential should have neutral to negative pressure in the hot aisle. To achieve this, you may need to install rack doors on contributing or affected racks. If this is ineffective to reduce air impediment, you may need to install a supplemental air removal unit to boost airflow through the equipment.
