INTRODUCTION
Tate's PowerAire® Variable Speed Quad Fan Assist device provides the user with unparalleled local control and reliability
of airflow to precisely meet individual rack cooling demands in areas of low or no static pressure without user
intervention. Automatic control based on user a defined set point guarantees that each piece of IT hardware installed in
the users rack is supplied with sufficient air volume at all times.
METHOD OF OPERATION
Tate's PowerAire® Quad Fan product is designed to work in conjunction with the DirectAire® Airflow Panels, to meet
high airflow requirements and accurate air flow deliver to the rack face. The PowerAire® Quad Fan is designed to
alleviate airflow issues in areas where little to no static pressure exists due to Underfloor restrictions, or insufficient
TM
floor heights. The PowerAire
Quad Fan is designed to function on most finished floor heights of 6" or greater. Since IT
loads are rarely stable on a rack to rack basis, the PowerAire® Quad Fan is designed to throttle the amount of air
delivered to an individual rack based on its current inlet air temperatures. This guarantees sufficient air delivery to the
rack, as hot air recirculation would occur in insufficient airflow delivery situations. This balancing act is managed by a
high speed PID controller which monitors each temperature sensor in a multi loop temperature evaluation mode. Each
of the three sensors installed at the rack face are polled for current temperature value, and then compared to each
other. The probe having the highest value is then used as the control point. This control point is then used to determine
the correct speed for the variable speed fan. The command signal is sent to the fan controller, which then changes the
fan speed producing more or less air to pass through the DirectAire® or other airflow grate.
