Function
•Air is supplied horizontally into the space through
temperature difference between supply and room air
the front panel of the diffuser
as follows:
•The supply air can be deflected in different
-8°C for 3 and 4 direction air supply
directions (1,2,3,4) with a recommended maximum air
-6°C for 1 and 2 direction air supply
DTR can also be used as an exhaust unit.
