Certification compact HVAC units

We are happy to let you know that ATREA has achieved another success to confirm we are a true leader in ventilation and heat recovery as we claim in our slogan.

It is a successfully completed PHI certification process for DUPLEX Flexi 650, 1100, 1600, 2600 and 3600 – it means for all Flexi units!

Let us tell those who are yet not closely familiar with this certification from their markets that Passive House Certification is a non-mandatory certification process of energy, acoustic and mechanical properties of ventilation units to receive a “Component suitable for passive houses” certificate. Although this certification is not mandatory, it is internationally known and generally recognized as one of the top awards given to products in our field.  

An environmental policy leader and member of many professional associations, ATREA is the only PHI-certified company in the Czech Republic and just the fourth in Europe to meet the really challenging criteria of this well-established institution for this size of HVAC units.
