Function
The Active Chilled Beam HDC is specifically designed for installation in false ceilings. In the cooling mode
room air is heated at the façade, entrained into the unit, cooled and recirculated to the space.
Primary air flow from internal metal nozzles, induces room air through a heat exchanger where it is cooled
or heated. The primary air is mixed with the heated or cooled secondary air and delivered into the room.
Hygienic operation is achieved by avoiding dehumidification of the secondary air.

Cooling mode
Room air heated at façade is drawn directly into the units where it is cooled. Supply air is diffused along the
ceiling, mixes with the ambient air to reduce air speed and temperature difference.

Intended Use
The induction unit type HDC is intended for use in closed rooms.
It is designed for ambient temperatures of +5
_
C to +40
_
C and a maximum relative humidity of up to 90%
(non--condensing).
The maximum admissible supply temperature is, therefore, limited to +80
_
C.
Any other operating conditions require the express and written permission of LTG Aktiengesellschaft.
LTG Aktiengesellschaft does not assume responsibility for any damages resulting from unintended use.
