The basic principle of the ATREA product range is since the beginning decrease of air-handling equipment operational energy demands, mainly by use of state of the art heat recovery exchangers, perfect built-in controls and gradual transition to fully automatic ventilation control systems.

The whole product range is currently divided into four areas - divisions:

1. Unit ventilators & heat recovery
    
2. Kitchen ventilation
    
3. Residential ventilation & warm-air heating
