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 200 mm air ducts.


The casing is made of expanded polypropylene (EPP) with high heat- and sound-insulating properties. Reneo S 550 L – left-handed unit.


The unit is equipped with high-efficiency EC external rotor motors and centrifugal impellers with backward-curved blades.



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


The Reneo S 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.

RENEO S 550 L   RENEO S 550 R


The Reneo S unit is equipped with a counter-flow polysterene heat exchanger for heat recovery. The condensate is collected and drained to the drain pan under the heat exchanger.


The Reneo S S14 units are equipped with an integrated automation system and an S14 wall-mounted sensor control panel.


The units are designed for suspended ceilling and floor mounting.
