An indoor ducted unit equipped with fresh air intake fan, exhaust fan for stale air, filter system, Lossnay sensible heat recovery unit.

By "Controlled Mechanical Ventilation" (CMV) is meant a system by which continuous and controlled air exchange is ensured in enclosed spaces. The air exchange achieved by opening windows is called ventilation and is, in all evidence, neither continuous nor controlled.

Within the plant engineering sector of residential ventilation there are several controlled mechanical ventilation systems, point (or decentralized) VMC and centralized ducted VMC. This second type of system includes the new model VL-220CZGV.

This is a dual-flow centralized ventilation unit with heat recovery that provides air exchange of the dwelling unit by extracting air from the service rooms and feeding filtered and pre-treated fresh air into the noble rooms.

It is equipped with two fans (one for the extract air flow and one for the supply air flow) and a double-flow heat exchanger for the passage (and thus recovery) of thermal energy between one flow and the other, obviously without the two flows mixing.

Thanks to these heat recovery systems, with recovery efficiency greater than 80%, the heat contained in the extracted air is transferred to the incoming air stream, reducing energy consumption and improving comfort in the rooms where the air intake takes place.
