A warm recommendation:
window ventilators with heat recovery.
SIEGENIA offers an extensive range of
innovative ventilation units for instal-lation
in or around windows. Whether
nearly invisible or visually striking, our
ventilation systems are more than just
powerful. They are exceptionally versa-tile
and flexible, thanks to their mod-ular
design. This allows even the most
demanding and unusual of projects to
be achieved exactly as planned.
Active or passive ventilators?
A fundamental property of a win-dow-
mounted ventilator is its classifi-cation
as an active or passive ventilator.
A passive device (without a fan) is based
on the natural pressure differential
between cooler outdoor air and the
heated, used air in the room and ensures
a controlled exchange of air. Where
there is an artificially created pressure
differential due to centralised or decen-tralised
ventilation (e.g. in the kitchen
or bathroom), a passive device ensures
there is a supply of fresh outdoor air.
An active ventilator has a motorised fan
to provide controlled ventilation.
Energy efficient ventilation.
The best example of the possibilities
and advantages offered by intelligent
ventilation technology is heat recov-ery.
Here, it is ultimately all about a fair
exchange. The heat in the used exhaust
air is transferred to the inflowing fresh
air through a special heat exchanger,
allowing the fresh air to be pre-heated.
This contributes to a healthy living envi-ronment
and provides lasting protection
for the building while saving energy ef-ficiently
in line with the German Energy
Saving Regulations (EnEV).
The heat recovery principle:
Fresh, cold outdoor air is drawn in
Used, warm air from the room is ex-traced
Path through the heat exchanger: the
heat from the exhaust air is trans-ferred
to the supply air, warming it up
Reduced heating costs and humidity
in the room
