Eliminate Server Leakage in Contained Cold Aisles
SmartAire® P or (pressure sensing) variable-air-volume damper is ideal for contained aisles or enclosed racks with equipment that have a variable load profile. Using constant airflow into a contained system with variable loads will waste energy during times of non peak load performance from airflow being forced through spaces around the racks and containment structure. As static pressure builds the air will also be forced through servers even if the fans are idle or off. This wasted energy can be solved with the use of SmartAire P.
By installing SmartAire® P under a portion of the airflow panels in the cold aisle the airflow can be varied based on a desired static pressure. When servers enter an idle state they will draw less air from the contained system causing the static pressure in the aisle to increase. The SmartAire® P is daisy chained to SmartAire® C units for a primary/secondary configuration that will automatically modulate all the dampers in the aisle to control the static pressure to maintain a user defined set point.

|Without SmartAire® P Dampers in the cold aisle to maintain a neutral static pressure in the cold aisle, conditioned air will leak through idle servers and other gaps in the containment structure.||SmartAire® P monitors the static pressure differential from the contained cold aisle to the hot aisle in order to maintain a balance when rack loads vary. This balance reduces bypass airflow through servers, racks and other containment structures.|
