SXI 113÷443
SLIM fan coil units for built-in installation with EC Inverter tangential fans
The SXI 113÷443 water terminals are designed to meet all installation requirements, whether vertical or horizontal recessed, in domestic or tertiary environments such as offices, hotels, restaurants, gyms and shops.
When part of a hydronic system equipped with a liquid Chiller, the unit generates cool air silently and with instantaneous reaction. While, during the winter, if combined with a thermal system, it provides warm air, making possible to meet home or business heating needs. An easily removable and cleanable air filter absorbs and retains dust in suspension keeping the air quality at a suitable level and allowing the execution of continuous cleaning cycles, which are particularly important to guarantee suitable hygiene standards, especially in highly frequented rooms.
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.
