The Subzero Engineering Velocity Adjustor is the most efficient way to balance subfloor air pressure in data centers.
The Velocity Adjustor is designed to lower velocity at the AC discharge to eliminate sub floor vortices that are formed when two high velocity currents of air converge. Slowing the air increases pressure, and this in turn creates a consistent supply of air to any part of the data center. The supply airflow through the sub floor plenum is the foundation of any cooling program. Inconsistent supply, due to high velocity airflow from CRAC, units prevents cooling air from getting to the computer intake, especially at the top of the rack. A balanced supply volume is essential in order to match the kW load in each cabinet.
