Blauberg KOMFORT EC D5B 180-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 reduce air conditioner load during hot season.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø 150 mm air ducts.

High-efficient external rotor EC motors and centrifugal impellers with forward 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 casing is made of expanded polypropylene (EPP) 15–30 mm thick with high heat- and sound-insulating properties.The spigots are located at the side of the unit and are rubber sealed for airtight connection to the air ducts.

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

The KOMFORT EC D5B 180 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 D5B 180-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 KOMFORT EC D5B 180(-E) models are equipped with a bypass which can be opened if there is a need to cool down the ventilated area with cool intake air.

The units are designed for suspended ceiling mounting, vertical or horizontal wall mounting.Sufficient service access for maintenance and filter replacement must be provided.

The KOMFORT EC D5B 180(-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 D5B 180(-E) S14 units are equipped with an integrated automation system and an S14 wall mounted sensor control panel with LED-indication.
