VXI 123÷614
Fan Coils units for built-in installations with 6-speed or EC Inverter centrifugal fans
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 installed in a hydronic system equipped with a water chiller or a thermal energy source, they generate cooled or heated air silently and immediately. The removable and washable filter traps airborne dust, ensuring constant cleaning cycles and high air quality, ideal for busy environments. Every installation requirement is met thanks to horizontal or vertical mounting, with front, rear or bottom air intake, and a wide range of accessories, including for 4-pipe systems, comprising a wide range of remote controls.
