DucoBox Energy Comfort D325

The DucoBox Energy Comfort D325 is designed for balanced ventilation systems with heat recovery. (System D) The unit efficiency is tested according to NBN EN308 and it has a high thermal efficiency of 85% according to EPBD (Belgium).

This smart and silent ventilation unit, with its various designs and adjustable capacity up to 325m 3 /h, is the solution for every situation in an indoor residential construction.

The unit intakes the fresh air into the service area and exhaust the dirty air. While doing this function, it also uses the heat of return air with the help of its heat recovery part. Thanks to the heat recovery section inside, this unit has a great thermal efficiency.

The demand control of the DucoBox Energy Comfort results in intelligent and energy-efficient operation . Together with the smart demand control based on CO2 and moisture, the dynamic air distribution filters ensure exceptional efficiency within this compact unit. It helps to decrease the energy bill!

Thanks to the unique principle of setting the comfort temperature, you can define the temperature per zone , for example 21.5° for the day zone and 18° for the night zone. This ensures significantly increased thermal comfort.

A closer look into freduction :

With the standard DucoBox Energy Comfort, it is possible to reach up to 0.56 freductionheat with the correct configuration.

With the optional multi-zone valve and correct sensor configuration of DucoBox Energy Comfort, it is possible to decrease freductionheat up to 0.45.

Please find different configurations of DucoBox Energy Comfort via the “Downloads" part of this page in the "DucoBox Energy Comfort -en Plus brochure” .

Optional compact external 2-zone (multi-zone valve):

With external 2-zone control, the home is divided into a day and night zone. The zone control works based on CO2 and humidity and only provides ventilation where and when necessary and in the right amount. Zonal ventilation results in maximum energy savings and increased acoustic and thermal comfort.

Discover the 4 advantages of the multi-zone valve:

Compact installation
The multi-zone valves are placed in the supply pipes (D125 or D160) and only require a free space of 78 mm . They can be used anywhere in the pipe system. The installer can make his own choice based on ease of installation, accessibility, etc.
Energy saving
With zonal ventilation we do not ventilate the entire home, but only the zones where people are active. That is why our systems have to work less hard, resulting in significantly lower energy consumption (40%) of the ventilation unit and the heating system.
Quieter operation
Reduced motor rotation ensures significantly quieter operation (30%) .
Increased thermal comfort
Thanks to the unique principle of setting the comfort temperature, you can define the temperature per zone , for example 21.5° for the day zone and 18° for the night zone. This ensures significantly increased thermal comfort.
