DucoBox Energy SKY D275 - plug type G

The DucoBox Energy SKY D275 is an energy-efficient ventilation unit with heat recovery (HRV unit) and a maximum airflow rate of 275 m³/h. This HRV unit is specifically designed for applications in compact spaces such as technical niches or lowered ceilings, typically found in apartment buildings. Thanks to its limited height of just 30 cm and lightweight design, both ceiling and wall mounting are easily achievable. The DucoBox Energy SKY combines smart technology with ease of installation and fits perfectly within the Duco Energy Family (system D).

Specifications

The ventilation unit is equipped with an efficient EC motor and supports features such as automatic balancing, 2-zone control via external dampers, a copy function for settings, and a convenient head-up display. The housing is made from durable expanded polypropylene (EPP), with a plastic cross-flow heat exchanger for optimal heat recovery.

Dimensions: 1180 mm high, 670 mm wide, and 295 mm deep. Weight: lightweight and suitable for ceiling mounting. Connections are located at the top (residential side and outdoor air side: duct end). The unit is equipped with ISO Coarse filters with an efficiency of 65% on both the supply and exhaust sides.

Application

The DucoBox Energy SKY D275 is ideal for modern apartments or homes where limited installation space is available. The unit supports communication via Modbus TCP and can be connected to home automation systems via the optional Duco Connectivity Board. Operation is possible via Wi-Fi (in combination with the Duco Installation App) or external wireless control. The unit is prepared for external CO₂ and humidity sensors and supports zone control. Not suitable for floor mounting or connection to central heating boilers.

A look into the f_reduction :

With the DucoBox Energy SKY D275, it is possible to achieve up to 0.56 f_{reduction heat} with the correct configuration.

With the optional multi-zone damper and the correct sensor configuration of the DucoBox Energy SKY D275, it is possible to reduce f_{reduction heat} to 0.45.

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

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

Discover the 4 benefits of the multi-zone damper:

Compact installation
The multi-zone dampers are placed in the supply ducts (D125 or D160) and require only 78 mm of free space. They can be used anywhere in the duct system. The installer can make their own choice based on ease of installation, accessibility, etc.
Energy savings
With zone ventilation, we do not ventilate the entire house, but only the zones where people are active. Therefore, our systems need to work less hard, resulting in a significantly lower energy consumption (40%) of the ventilation unit and the heating system.
Quieter operation
The reduced rotation of the motor results in significantly quieter operation (30%).
Greater thermal comfort
Thanks to the unique principle of setting the comfort temperature, you can determine the temperature per zone, for example, 21.5° for the day zone and 18° for the night zone. This results in significantly increased thermal comfort.
