Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Heat recovery minimizes ventilation heat losses during the cold season and reduces air conditioner load during the hot season. Controllable air exchange for creating the best suitable indoor microclimate. Compatible with round 160 mm air ducts.


The casing is made of expanded polypropylene (EPP) with high heatand sound-insulating properties.


High-efficient external rotor EC motors and centrifugal impellers with forward-curved blades are used for air supply and exhaust.



Two built-in Coarse 90% (G4) filters provide efficient supply air filtration. Supply ePM1 65% (F7) filter available as an option.


The Reneo D...-E unit is equipped with an enthalpy counter-flow heat exchanger for heat and humidity recovery.


The Reneo D units are equipped with a bypass, which can be opened if there is a need to cool down the ventilated area with cool intake air.


The units are designed for suspended ceilling mounting, floor mounting, vertical or horizontal wall mounting.


Reneo D S21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set. The S21 controller allows integrating the unit into the Smart Home system or BMS (Building Management System). Unit control via Wi-Fi using the mobile application Blauberg Home.
