DESIGN AND FUNCTIONING

Warm stale extract air from the room flows into the unit, where it is filtered by the extract filter, then air flows through the heat exchanger
and is exhausted outside by the extract fan.
Clean cold air from outside is moved to the supply filter. Then filtered air flows through the heat exchanger and is moved to the room
with the supply fan.
Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up.
Heat recovery minimizes thermal energy losses and space heating expenses in cold seasons.
The unit is equipped with a detachable service panel for repair and maintenance operations and a cover enabling access to the control
system components.

The basic unit delivery set includes a control panel for connection to the control system inside the unit casing using a data cable.
The unit is equipped with supply and extract centrifugal single-inlet fans with backward curved blades; maintenance-free EC motors with
an external rotor and a built-in overheating protection; a plate counterflow heat exchanger and an water heater.
The supply G4 filter cleans supply air flow and prevents contamination of the unit parts.
The extract G4 filter prevents contamination of the unit components.
Some condensate may form during heat recovery. The condensate is collected in the drain pan and is removed from the unit through
the drain pipes.
