Arrangement of efficient energy-saving supply and exhaust single-room ventilation in flats, houses, cottages, social and commercial premises.
Heat recovery minimizes ventilation heat losses.
Humidity balance and controllable air exchange create individually set microclimate.
Coordinated network based on several integrated single-room ventilation units with central control.


Warm stale air is extracted from the premise, flows through the ceramic regenerator and transfers a part of the accumulated heat and moisture to it. In 70 seconds, after heating of the ceramic regenerator, the unit switches to the supply mode.

Clean cold intake air flows through the regenerator and absorbs accumulated heat and humidity. In 70 seconds, after cooling of the ceramic regenerator, the unit is switched to the extract air mode.
