The primary air volume flow required for fresh air supply enters the upper plenum box through a connecting spigot and is then discharged into the mixing zone via nozzles which are fitted into a diaphragm plate.

The induced air is for hyiene reasons drawn from the room instead from the ceiling void. When the air passes through the water coil it is cooled down (chilled water operation) or warmed up (warm water operation). In the mixing section of the

DID600B-L the induced air is mixed with the primary air and the total discharged into the room via slots. The DID600B-L can be used for cooling and/or heating. An additional spigot for extract of exhaust air can be fitted adjacent to the primary air duct (supply and extract air construction).

In terms of technology and appearance the DID600B-L active chilled beam offers a sophisticated solution for modern air conditioning and lighting requirements.
