Blauberg KOMFORT EC S5B 270-E S21

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat recovery minimizes ventilation heat losses during cold season and reduces air conditioner load during hot season.Controllable air exchange provides the best indoor microclimate.Compatible with round Ø 125 mm air ducts.

The casing is made of expanded polypropylene (EPP) plates, 15–26 mm thick, possessing high heat- and sound-insulating properties.The unit is equipped with service panels for convenient maintenance of filters and heat exchanger.The spigots are located at the top of the unit and are rubber sealed for airtight connection to the air ducts.

The built-in G4 supply filter and G4 extract filter provide air filtration.The F8 supply filter (specially ordered accessory) may be used for efficient supply air filtration.

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.

The KOMFORT EC S5B 270(-E) models are equipped with a bypass which can be opened to cool down the ventilated area with cool intake air, if required.

The KOMFORT EC S5B 270 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 KOMFORT EC S5B 270-E unit is equipped with an enthalpy plate counter-flow heat exchanger for energy (heat and humidity) recovery. Due to humidity recovery condensate is not generated in the enthalpy 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.

The ventilation units are designed for wall and floor mounting.Due to universal casing design both left and right mounting is possible.

The KOMFORT EC S5B 270(-E) S21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set (sold separately). 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 AHU.

The KOMFORT EC S5B 270(-E) S14 units are equipped with an integrated automation system and the S14 wall mounted sensor control panel with LED-indication.
