How the Q-R works.
A flat box on the floor that lets cool air out very slowly through a perforated face plate. A cool layer forms 10 – 30 cm above the floor.
Applications: comfort rooms, in front of wall, parapet or column, free-standing or in furniture (p. 2); the data sheet shows the restaurant of the Koninklijke Schouwburg, The Hague (p. 5). Krantz reference in the Netherlands also: Rijksmuseum, Amsterdam (Q-R product page, old Peek site)
