Zehnder Comfort ventilation unit ComfoAir Q450 TR with integrated Display

The Zehnder ComfoAir Q450 TR is a central, compact ventilation unit with heat recovery and integrated summer bypass. This ventilation unit is ideal for new builds as well as refurbishment projects. The housing, made of galvanised and painted sheet steel, is acoustically and thermally insulated. Energy-efficient DC fans ensure economical operation and therefore high electrical efficiency. The supply-air and extract-air fans can be controlled separately and can be set with percentage accuracy by entering the balanced airflow rate. At the heart of the ComfoAir Q450 TR is a plastic counterflow heat exchanger with a heat recovery efficiency of more than 90%. The unit is operated via the integrated control panel. Alternatively, operation can be via a wired control unit (ComfoSense C or ComfoSwitch C), connected to the ventilation unit with an on-site cable (JYSTY 2x2x0.6). The unit can also optionally be operated via the ComfoConnect LAN C or ComfoConnect KNX C interfaces. All operating states and fault messages are visible on the display. The ComfoAir Q450 TR is supplied ready to plug in. The filters are located at the front and can easily be replaced by the user without opening the unit. The ComfoAir Q450 TR can be installed either wall-mounted or floor-standing using an optionally available base. Connection is via 4 rotatable DN 160 connection spigots facing upwards or sideways.
