Mechanical Extract Ventilation


Mechanical Ventilation with Heat Recovery

Demand-controlled ventilation

The room is only ventilated when necessary and in the correct amount. CO2 concentration and air humidity are used as indicators. This helps avoiding unnecessary heat loss while guaranteeing an optimal indoor climate.

How does it work?

Sensors permanently measure the indoor air quality in a room (or centrally, depending on the case). These sensors are located in the rooms or in the ventilation box itself.

If the indoor air quality (CO2 or humidity) is found to be OK, the ventilation is put to a strict minimum:

  • Minimum energy consumption
  • Minimum heat losses

On the other hand, if the indoor air quality is found to be or become worry-some, the ventilation is triggered immediately in a modular way, i.e. more or less intense according to intelligent algorithms. The energy is only used when needed to reach healthy indoor air.

With an “on demand” DUCO-system, the occupant can always be assured to breathe the best possible indoor air, whilst also using the least amount of energy!

Automatic calibration

The automatic calibration, whereby the measuring and adjustment technology is based on the principles of calibration under constant pressure, always offers a 100 % guarantee of a qualitative end result and translates into a 50 % saving in set-up time for the installer.
