Where do the devices fit best?
The devices with a Ø160 channel dimension are recommended here as they are the quietest devices. These are the DUKA One S6, S6 Wi-Fi, Pro 50 S, Pro 50 S Wi-Fi and the D6 devices.
The DUKA One S4 / S4 Wi-Fi and Pro 25 S / Pro 25 S Wi-Fi can also be used in sleeping and living areas.
For basement rooms, DUKA One S6, S6 Wi-Fi, Pro 50 S, Pro 50 S Wi-Fi and D6 can be used. In basement rooms where there is a telescopic valve or 150×150 mm fresh air valve, this can be upgraded with a Ø100 unit such as DUKA One S4 Plus, DUKA One S4 Plus Wi-Fi, DUKA One Pro 25 S, DUKA One Pro 25 S Wi-Fi or DUKA One C4.
Here's what you need to do DUKA One S6B Used if it is Ø160
DUKA One Pro 25 B If it is Ø100, or an upgrade of existing 150×150 hole in the facade.
DUKA One are one-room ventilation solutions and one Ø160 mm unit covers up to 27 square metres for ventilation improvements in existing homes. We recommend one unit per room and more if the room is larger than 27 square metres. Note: For new builds, where there are requirements according to the building regulations, see the data sheets for the individual products here.
The DUKA One models with a Ø100 mm pipe diameter can handle a room of up to 15 square metres with ventilation improvements. We recommend one unit per room and more if the room is larger than 15 square metres.
The DUKA One runs in a continuous circular process where hot used air is sucked out of the room for 70 seconds. As it passes through the exchanger, the heat is stored in the ceramic exchanger and recycled. The unit then changes direction to fresh air supply, where fresh air from outside is blown through the exchanger and preheated via the exchanger. For 70 seconds, the heat from the exchanger is transferred to the supply air, after which the unit changes direction again.
If there are several devices in a room, they can be connected to work together as two or more devices. They can be connected by cable and Wi-Fi devices can be connected wirelessly.
If one unit is fitted, it will create a small over- or underpressure for 70 seconds. However, the over- or underpressure will be so low that it is not really significant. If multiple units are installed, it can be set via the DIP switches whether a unit starts blowing air in or blowing air out, so unit 1 blows air in while unit 2 blows air out to maintain an even pressure.
