SEMCO LLC has introduced the LYRA II, a 2- by 2-foot active chilled beam cassette capable of personalized pinpoint temperature and humidity via a digital controller. The LYRA II is a quiet, cooling/heating chilled beam capable of precise airflow patterns and velocities for spaces under 300 square feet in new construction and retrofit applications. It features 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-feet per minute. Its 8 1/2-inch-deep enclosure is designed to suppress turbulence and operational airflow noise to below 20-dB levels.
