AN-0 v0 Active Flow Control Theory and Application
The Active Flow Controller is a deta-P (pressure) controller that can be paired with an aisle containment system. The controller works by sensing pressure inside the aisle to adjust cooling unit fan speed. This prevents forced-mixing of hot and cold air.

AN-90 v3 Rack Air Containment Application Guidelines and Approved Configurations
The Rack Air Containment System (RACS) is a modular front and rear plenum for use in isolating the supply and return air between an APC Netshelter SX rack enclosure and an APC InRow™ cooling solution. The containment system is designed to create a separate environment for air distribution in order to prevent mixing of hot and cold air streams, resulting in a more predictable cooling pattern. The modular design and ability to retrofit to an existing Netshelter SX rack enables medium to high density racks to be cooled in an autonomous environment without overcooling the room mixed with lower density loads.

AN-146 v1 Hot Aisle Containment Application Guidelines and Approved Configurations
The Hot Aisle Containment System (HACS) is a modular ceiling panel and door system for use in isolating the supply and return air between an APC NetShelter rack and an APC InRow® cooling solution. The containment system is designed to create a separate environment for air distribution in order to prevent mixing of hot and cold air streams, resulting in a more predictable cooling pattern. The modular design and ability to retrofit to an existing Netshelter rack enables medium to high density racks to be cooled in an autonomous environment without overcooling the room.

AN-159 v0 Hot Aisle Containment System (HACS) and Data Center Fire Protection
The design of data centers around Hot Aisle Containment Systems (HACS) is growing in popularity. Engineers and, increasingly, Authorities Having Jurisdiction (AHJ) are questioning the need for fire protection in the hot aisle; specifically: incipient stage fire detection (high sensitivity smoke detection), smoke detection, fire suppression, sprinkler protection. This application note describes fire protection strategies for hot aisle containment systems. It is intended to clarify questions regarding detection and suppression requirements as applied to asset protection as well as address misconceptions within the HACS space.
