Blauberg KOMFORT ЕС DW
- Designation key
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat recovery minimises ventilation heat losses.Provide controllable air exchange to create the best suitable indoor microclimate.Compatible with round Ø 200 to 400 mm round air ducts.
The casing is made of double-skinned aluzinc panels, internally filled with 20 or 25 mm mineral wool layer for heat and sound insulation.The casing has fixing brackets with vibration absorbing connectors for easy installation.The spigots for connection to the air ducts are located at the side of the unit and are rubber sealed for airtight connection to the air ducts.The service panel ensures easy access to the internals for cleaning, filter replacement and other maintenance operations.
High-efficient external rotor EC motors and centrifugal impellers with backward curved blades are used for air supply and exhaust.EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers.

|HEAT RECOVERY||AIR FILTRATION|
The unit is equipped with a plate cross-flow (KOMFORT EC DW600/1000) or a plate counter-flow (KOMFORT EC DW2000/2800) aluminium heat exchanger for heat recovery. In the unit condensate is collected and drained to the drain pan under the heat exchanger.
FREEZE PROTECTIONThe electronic frost protection system based on bypass and heater is used to prevent the heat exchanger freezing in cold seasons. The bypass damper is opened and the heater is turned on automatically according to the feedback from the temperature sensor. Cold intake air passes by the heat exchanger and is warmed up to set temperature in the heat exchanger. Synchronously extract air that passes by the heat exchanger is used for its defrosting. After a freezing danger is over the bypass damper is closed, the heater is turned off. The unit reverts to the normal operation mode.
The built-in G4 supply filter and G4 extract filter provide air filtration.
|CONTROL AND AUTOMATION|
The unit incorporates an integrated control system with a wall-mounted control panel and a sensor display.The standard delivery set includes a 10 m cable for connection of the unit and the control panel.Automation functions:
The unit is equipped with a water (glycol) heater for operation at low outside air temperature.The integrated water heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only.Heat medium temperature control ensures supply air temperature maintaining.The air temperature sensor downstream of the waterheating coils and the return water temperature sensor are used for freezing protection of the water heater.
Mounting to the ceiling with fixing brackets.The correct mounted unit must provide free condensate collection and drainage as well as good access for servicing and filter replacement.Servicing access:
