Heat exchanger KPI

Introducing fresher air MAXIMUM FRESH AIR – Choose from three operating modes: free ventilation, automatic ventilation and heat recovery, to maximise air renewal, save energy and improve air conditioning performance. AUTOMATIC CO2 REDUCTION – With the optional CO2 sensor, the KPI manages indoor carbon dioxide levels, either by removing CO2 constantly to maintain consistent air quality, or by rapidly refreshing the air when high levels are detected. LOW NOISE LEVELS – When you need quieter operation, the sound attenuator reduces noise by up to 5 db(A) compared to standard models.
