Enthalpy with Integrated Display

The Zehnder ComfoAir Q450 TR Enthalpy
is a central, compact

and integrated summer bypass. This
ventilation unit is perfectly suited
for new buildings as well as for
renovation projects.
The housing, made of galvanized and painted
sheet steel, is
sound and thermally insulated.
Economical DC fans ensure
economical operation and
therefore enable high
electrical efficiency. Supply and
extract air fans are separately
adjustable and can be
set to the exact percentage by entering
the balanced air volume.
The core of the ComfoAir Q450 TR Enthalpy
is the plastic cross-counterflow heat exchanger

operation can be carried out via a
wired control unit
(ComfoSense C or ComfoSwitch C), which
is connected to the ventilation unit
with a cable provided by the customer
(JYSTY 2x2x0.6). Alternatively, operation
can also be carried out via the interfaces
ComfoConnect LAN C or Comfoconnect
KNX C.
All operating statuses and
error messages are visible on the display.
