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).
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.
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.
With the DucoBox Energy SKY D275, it is possible to achieve up to 0.56 freduction 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 freduction heat to 0.45.

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.
