The Sitali CX 400 ducted HRV unit, dual-flow with heat recovery, can be installed vertically on the wall (with left or right configuration, for maximum flexibility) and is distinguished by its high energy efficiency: class A+ and very low-consumption brushless EC motors. It has a maximum air flow rate of 363 m3/h and comes with a multifunction control panel, from which the unit's weekly programming can be set, as well as ventilation speeds, and fault or filter replacement indicators can be displayed. Thanks to the built-in physical bypass, the Sitali CX 400 unit is ideal for free cooling operation during the summer season.
