The Ducted Blower Fan Coil units of the DBW-M series are designed for installation in wide ambients as office buildings, hotels, restaurants, sport structures and shopping malls.
If connected to a system equipped with a water chiller, DBW-M generates cool or warm air silently and with instantaneous reaction. The range includes 27 models with cooling capacities from 16 to 83 TON, characterized by high static pressure (up to 1,4 inWG) to satisfy the needs of extra wide installations where external unit is far from the internal ambients or there are multiple ambients to be cooled simultaneously. Each model is available in versions with 3, 4 or 6 rows and features both horizontal and vertical air delivery.
A filter, which absorbs and retains dust in suspension, allows to keep the air quality at a suitable level and its easy removal enables continuous cleaning cycles to be carried out which are particularly important in order to guarantee suitable hygiene standards in highly frequented rooms.
 
The units feature 380V power supply and 60Hz frequency.
