Air principle
From outlet to occupied zone.
At the outlet
Rotating cylindrical elements, each with two jet channels, form a row of many individual jets. (DS 4082e p. 2)
In the room
Those jets induce strongly. You set their direction per element: two-way over 0 – 20° or 0 – 40°, one-way, or closed. (DS 4082e p. 2–3, p. 14)
Construction
An aluminium profile, as contact edge or as ceiling support profile, carrying the linear element of rotating cylinders. Above it a plenum box with spigot, optionally with damper and insulation, and an end suspension. (DS 4082e p. 4–6)
Smoke test
Airflow in the Krantz lab.
A real smoke test in the Krantz flow laboratory: this is how air leaves the IN-V.

Finish
profile natural anodised or RAL 9010; element black or white (p. 13)
In the ceiling
in suspended metal and plasterboard ceilings, with ceiling support profile or flush contact profile (DS 4082e p. 2, p. 4–6). For ceiling panels there is an additional profile, the IN-V XTRA (So-DS 4082 E 01.2017 p. 1–2).
Applications
Where it belongs.
Commercial rooms where air distribution should disappear into the ceiling, especially with the narrow IN-V3 (DS 4082e p. 2).
Krantz references in the Netherlands: De Nobel, Leiden (IN-V2); Shell, Rijswijk (IN-V); SNS Reaal, Utrecht (IN-V2); Slotervaart Hospital, Amsterdam (IN-V2 in plaster ceiling)
When not: Above 5 m discharge height the IN-N6 fits (4 – 7 m, fixed discharge direction, DS 1125 E p. 2).
