DESIGN AND OPERATING PRINCIPLE
The unit has the following operating principle: Warm stale extract air from the room flows to the unit, where it is filtered. Then the air is
moved through the rotary heat exchanger and is exhausted outside with the extract fan.
Clean cold air from outside is moved to the intake filter. Then filtered air flows through the rotary heat exchanger and the electric heater
(for the VUTR 280 VE EC units) where it is warmed up to the set temperature 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 heat losses and space heating expenses in cold seasons and cooling expanses in warm seasons.
The unit is equipped with an additional extract spigot for connecting a kitchen hood.
