cooling in a room. QPSA is a narrow, passive chilled beam (width 290 mm), QPBA is a broad passive chilled beam (width 430 mm), and QPDA is our new passive chilled beam with a designer casing (width 400 mm). The passive chilled beams are either ceiling installed, in which case they lie flush with the suspended ceiling, or free space installed without ceiling. QPDA can only be free space installed. The passive chilled beams are available in lengths 1.2-4.2 m (not QPDA, which is only available in sizes 1.8 and 4.2 m) at 60 cm intervals. In installations with passive chilled beams the air is supplied by means of separate supply air valves.
