Passive house standard for ventilation unit series M-WRG-II from Meltem

With the new M-WRG-II device series, Meltem is well equipped for use in passive houses. On March 13, 2019 at the ISH Julia Sophie Weiser and Dipl. Phys. Oliver Kah from the Passive House Institute presented Mathias Kwak, Technical Product Manager at Meltem, the certificates for the two device series M-WRG-II P and M-WRG-II E. The device series P is equipped with a cross-countercurrent heat exchanger , the device series E with a cross-countercurrent heat exchanger with moisture recovery. The units are the first decentralized ventilation units to be fitted in series with an ISO ePM1 60% (F7) outside air filter.

The M-WRG-II ventilation units meet all the standards specified by the Passive House Institute for installation in passive houses. They enable economical and responsible use of valuable thermal energy and are therefore particularly suitable for future-oriented building equipment.
