Underfloor/Chilled Beams

When Supplemental Cooling for Chilled beam applications are required Best Technology’s advanced aero-acoustical expertise can be combined with chilled beam and conductive cooling systems. The result is quiet operation of an NC-35 in the space and ultimate control of air delivery at the highest energy efficiency within a compact floor space.

The unique and innovative design of the Best Air columns produce superior results to those achieved by the application of conventional systems, reducing noise levels, internal pressure drops, and energy in the smallest footprint available in the industry today.

Our advanced aero-acoustic technology combined with pressurized air distribution systems result in critical quiet operation and definitive control of air conveyance. BEST Technology’s air columns dispense fluid flow at specific entrainment patterns for applications requiring Floor by floor, and large volume air systems.
