|FeaturesAir handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat recovery minimises ventilation heat losses.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø 125 and 160 mm air ducts.
DesignThe casing is made of double-skinned aluzinc panels, internally filled with 40 mm mineral wool layer for heat and sound insulation.The panel of the casing ensures easy access to the internals for cleaning and other maintenance operations.The spigots for connection to the air ducts are located at the sides of the unit and are rubber sealed for airtight connection to the air ducts.
FansHigh-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.
Air filtrationThe built-in F7 filter provides efficient supply air filtration.The G4 filter is used for extract air filtration.
BypassThe units are equipped with the 100 % bypass for summer ventilation (room cooling by the cool intake air).
The unit is equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger.The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air.Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively.In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity.
MountingThe units are designed for ceiling or wall mounting.The mounting place must provide enough space for connection to drain system and condensate drainage using the SFK 20×32 kit (available separately).
|Control and automationThe KOMFORT EC DB S21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set (available separately). The S21 controller allows integrating the unit into the Smart Home system or BMS (Building Management System). The unit can be controlled by the Blauberg AHU mobile application via Wi-Fi.
The KOMFORT EC DB S14 units have an integrated automation system with a wall-mounted control panel S14 with a LED indication.
