DucoBox Energy Comfort (Plus)
First choice for any situation in residential construction

The DucoBox Energy Comfort Plus has been developed for application of balanced ventilation with heat recovery. With its various versions and adjustable capacity of up to 550 m3/h, this smart and silent ventilation box is the solution for any situation in residential construction. The left/right exchange is 100% software-based thanks to a patented principle of double bypass. The dynamic air distribution filters, together with the smart demand control based on CO2 and humidity, ensure exceptional efficiency.

Patented principle of double by-pass

L/R interchangeable 100% software-based

Smart 2-zone control with external valves

Dynamic Airflow Filters for maximum efficiency

Comfort Plus with acoustic casing = 10dB quieter!

Low power consumption thanks to energy-efficient EC motors

Smart demand management based on CO2 and/or humidity measurement

MAXIMUM RELIEF FOR THE INSTALLER

Save time = Save money
Based on the principles of constant pressure calibration , autocalibration saves 50% on adjustment time. This quickly means a saving of 30 on the installation cost for a standard calibration!
Want to save even more time and money? This is possible thanks to the handy copy function. By integrating a copy function into the software, it is possible to take over the settings within similar houses in serial construction. This results in an additional saving of 15 per installation.

Left/right interchangeable
This unit is very lowthreshold as physical interventions are not required. The left/right exchange is 100% software-based thanks to the patented principle of double by-pass.
Compact external 2-zone
The external 2-zone valve controls on the basis of CO2 and provides ventilation only where and when needed. Thanks to the 70% rule, the supply flow rate can be calculated up to 785 m3/h.

Duco Installation App
The new Duco Installation App ensures perfect calibration of the ventilation system. Moreover, you can use the app to create an official ventilation report in no time.

Acoustic damping
The acoustic casing ensures quieter operation of the system. The result? Extra attenuation up to 10 dB. Quiet and acoustic ventilation guaranteed.

TOTAL VENTILATION SOLUTION
Looking for a total ventilation solution? Then you prefer to focus on one single address. From ventilation boxes to vents. DUCO has everything you need for a healthy, comfortable and energy-efficient indoor climate. A wellfunctioning ventilation system preferably consists of a global installation with high-quality components.
