Blauberg KOMFORT ERV D S20
- Capacity diagram
- Designation key
Air handling unit for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Heat and humidity recovery minimizes ventilation heat losses during cold season and reduce air conditioner load during hot season. Controllable air exchange ensures the best suitable indoor microclimate. Compatible with round Ø 100 or 150 mm air ducts.DESIGN
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 at 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 underthe ceiling.
Asynchronous motors are used for air supply and exhaust. KOMFORT ERV D150 S20, KOMFORT ERV D250 S20 and KOMFORT ERV D350 S20 are equipped with a centrifugal impeller with forward curved blades. Integrated overheating protection with automatic restart. Ball bearings for longer service life. Dynamically balanced impellers. Featured with reliable and low-noise operation.
The unit is equipped with an enthalpy plate cross-flow heat exchanger for enegry (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.FROST PROTECTION
The integrated automatic freeze protection is used to prevent freezing of the heat exchanger in the cold season. The supply fan turns off according to the temperature sensor to get the heat exchanger warmed up with extract air. After that the supply fan turns on and the unit continues to run in the standard mode.
|CONTROL AND AUTOMATION
Integrated control system based on triac speed controller CDT1 E.AIR FILTRATION
Two built-in G4 and F8 filters provide efficient supply air filtration. The G4 filter is used for extract air filtration.MOUNTING
Due to the low casing height the unit is the ideal solution for mounting in the limited space behind the suspended ceiling. The installation place must be easily accessible for servicing.
