Active chilled beam cassette
SEMCO's LYRA II has personalized pinpoint temperature and humidity via digital controller for new construction and retrofit applications.
SEMCO LLC’s LYRA II is a 2 x 2-ft active chilled beam cassette capable of personalized pinpoint temperature and humidity via a digital controller. The LYRA II is an ultra quiet, cooling/heating chilled beam capable of precise airflow patterns and velocities for smaller spaces under 300 sq ft. It features personalized air comfort with digital field-adjustment capability of one, two, three, or four-way air directionality to accommodate any room shape or configuration. It also digitally controls discharge velocities ranging from 11 to 150-ft/min. Its 8.5-inch-deep enclosure is designed to suppress turbulence and operational airflow noise to below 20-dB levels. This chilled beam comfort control is accomplished with the optional pressure independent (Pi) controller, a 4 x 4-in digital microprocessor. The Pi is integrated with an on-board, electro-mechanical module that uses a 24-V powered motor to adjust the cassete’s airflow blades, nozzles, and volume dampers.
