The units include an easily removable, plastic heat exchanger which transfers warmth from the outgoing waste airstream into the incoming fresh air where its thermal efficiency exceeds 90%. At no point do the airstreams mix. Having the latest, low energy EC fan technology, the DV250, DV300 and DV400 comply with the ErP 2015 standards and are tested by TUV laboratories.
