Blauberg KOMFORT ERV D S41

Air handling unit for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat and energy recovery enables reduction of air conditioning load in hot climate conditions and heat losses in cold climate conditions.Controllable air exchange ensures the best suitable indoor microclimate.Compatible with round ∅ 100 or 150 mm air ducts.

The casing is made of polymer coated steel panels, internally heat- and sound insulated with 5–10 mm (depend on modification) polyurethane foam.The bottom service panel provides easy access for maintenance of the filters and the heat exchanger.The spigots for connection to the air ducts are located on the sides of the unit and are rubbed sealed for airtight connection to the air ducts.The mounting brackets on the casing ensure easy installation under the ceiling.

The units are equipped with three-speed external rotor motors with centrifugal impellers and forward curved blades.Integrated overheating protection with automatic restart.Ball bearings for longer service life.Dynamically balanced impellers.Distinguished with reliable and low noise operation.

Two built-in G4 and F7 filters provide efficient supply air filtration.The G4 filter is used for extract air filtration.

The unit have the integrated S41 control panel with the functions:

• Unit On/Off
• Speed selection
• Setting indoor air temperature
• Setting week scheduled operation

The unit is equipped with a plate cross-flow enthalpy aluminium heat exchanger.Heat recovery is based on heat and moisture transfer between the extract and supply air streams through the heat exchanger plates. The air flows are fully separated while flowing through the heat exchanger.The process of heat transfer proceeds in the heat exchanger where extract air transfers most of its heat to the intake air flow. This reduces heat energy losses in cold seasons. In summer heat recovery acts reverse: the cooled extract air transfers part of cold to the warm intake air. This contributes to better performance of the air conditioner in ventilated premises.

Due to the low casing height the unit perfectly fits for mounting in the limited space behind the suspended ceiling.The unit mounting position must provide access for service maintenance.
