SXM 113÷443
SLIM fan coil units with cabinet and EC Inverter tangential fans
The hydronic Fan Coil units with cabinet, SXM 113÷443, feature an exclusive and compact design combined with the highest efficiency and noiseless operation.
Part of an hydronic system equipped with a liquid Chiller, they generate cool air silently and with instantaneous reaction. During the winter, if combined with a thermal system, they provide warm air, making it possible to meet heating needs. A filter, easily removable and washable, absorbs and holds suspended dust, allowing constant cleaning cycles and maintaining an adequate air quality, in accordance with hygiene standards, especially in high occupancy locations.
The units, equipped with EC Inverter motor, modulate the air flow adapting the performances instant to instant to the actual needs of the room to be conditioned, thus assuring a total comfort with greater energy savings.
