VXI 123÷614

Fan Coils Units for built-in installations with 6-speed or EC inverter centrifugal Fans

_icona_clint_solo_raffreddamento-riscaldamento_2024.png

The VXI 123-614 water terminals are designed to meet all installation requirements, whether vertical or horizontal recessed, with front, rear or bottom intake, 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 product range is completed with a wide range of accessories, also for 4-Pipe systems, which includes a complete control panel collection, that can be installed on-board or in the room.
Units are available both with 6-Speed or EC Inverter fans. 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, assuring a total comfort with greater energy savings.
