Semco-052013-body.jpgSemco LLC has launched its IQHC (high capacity) Series of active chilled beams that provide high efficiency cooling/heating. They are specifically designed for the loads of North American commercial building applications at hospitals, office buildings, and schools. The manufacturer claims the IQHC offers one of the industry's highest capacities, but features up to a 25% and 50% reduction in pump and fan horsepower respectively, versus conventional chilled water loop or rooftop forced air HVAC system methods.  The quick-installing IQHC eliminates hours of site coordination time because of five universal 6-in diameter duct knockouts with spin-fit collars located in the top or any of the four sides and universal water piping connection locations. Each beam easily snaps into two included mounting brackets. Company officials said that competing brands use factory-set airflow nozzles that require replacement or pressure balance calibrations for cfm rate changes, whereas Semco's design features a proprietary 12-slot nozzle that's field-adjustable with two hand-operated levers. The integral flow pattern control can also be angled as much as 45 degrees to address room hotspots. The nozzle adjustment additionally provides a unilateral, disproportional or equal air volume from each side. The beams can be installed in a ceiling grid or as a pendant, the latter which highlights the IQHC's 22-gauge construction and powder-coated finish.
