UTW/HDT 63÷274
Ductable Fan Coil units with High Delta Water Temperature
These modular Fan Coil units are the ideal solution to meet the air treatment needs of systems including distribution through ducting or directly into the room and installation in false ceilings or in service rooms.
It has been especially designed for operation with High Delta Water Temperature.
If connected to a system equipped with a liquid Chiller, this terminal unit generates cool air silently and with instantaneous reaction. 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.
This product range is complete with various accessories such as: outdoor air intake plenum, mixing section with dampers, room delivery plenum for flexible ducts and resistance heating section. Units are available both with AC and EC Inverter fans.The units equipped with EC Inverter motor are able to modulate the air flow ensuring a perfect adaptability to the load without any temperature fluctuations, achieving superior performance compared to the traditional solutions even from the point of view of the energy consumption.
