YORK® Bulkhead Active Chilled Beams Energy Efficiency Delivered YORK® bulkhead chilled beams are the air distribution device of choice in high performing energy efficient buildings. Utilizing an integrated sensible cooling coil, active beams reduce the volume of air required for space cooling. A smaller volume of primary air minimizes energy consumed treating outdoor air and nearly eliminates energy wasted by parasitic reheat. When compared to conventional VAV systems a 30% energy savings can be realized. Superior Performance Aerodynamically designed nozzles inject conditioned primary air into...

1. All performance data based on test performed in accordance with ASHRAE Standard 200-2015 2. APr . values are measured in inches of water 3. NC values are based on room absorption of 10 dB. A dash (-) indicates an NC value less than 15 4. Throw values are based on isothermal supply air and represent throw distances to terminal velocities of 150, 100 and 50 fpm respectively 5. AP . values are measured in feet of water. AP . values in shaded cells indicate use of a two circuit coil. All other values Coil    Coil represent a single circuit coil. 6. Induction ratio is multiplied by the volume flow...
