VR 250 ECH/B is a complete ventilation unit for supply of filtered and preheated outdoor air to residential
areas and extract of a corresponding amount of used air from wet rooms and kitchen. The unit is equipped
with a heat exchanger block to ensure safe and economical ventilation.
VR 250 ECH/B is especially designed for installation in flats and apartments where duct runs, smells and
pollution from the kitchen extract (cooker hood) often is a great challenge. A damper solution in the
VR 250 ECH/B makes is possible to connect the unit to cooker hood. The kitchen extract goes directly to
the extract fan avoiding fumes and pollution to be led into the heat exchanger.
The unit will automatically alternate between winter operation with heat recovery and summer operation
without heat recovery.
