Blauberg KOMFORT ERV EC DB
- Designation key
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Reduction of load on air conditioning systems in a hot climate and heat loss in a cold climate due to heat and moisture recovery. Control of air exchange for creating comfortable indoor microclimate. Compatible with round Ø 100 or 150 mm air ducts.FANS
The unit is equipped with high-efficient external rotor EC motors used for air supply and exhaust. The KOMFORT ERV EC DB 100 S14, KOMFORT ERV EC DB 150 S14 and KOMFORT ERV EC DB 250 S14 units are equipped with a centrifugal impeller with forward curved blades and the KOMFORT ERV EC DB 350 S14 units – with backward curved blades. 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. The impellers are dynamically balanced.
The casing is made of polymer-coated steel panels, internally filled with foamed polyurethane layer 5-10 mm (depend on modification) for heat- and sound-insulation. The unit is equipped with a removable bottom panel for ease of maintenance. This service panel is used to access the filters and the heat exchanger for maintenance operations. The spigots are located at the sides of the unit and are equipped with rubber seals for airtight connection to the air ducts. The casing is equipped with fixing brackets to suspend the unit to the ceiling.
The unit is equipped with an enthalpy plate cross-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.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.AIR FILTRATION
Two built-in G4 and F8 filters provide efficient supply air filtration. The G4 filter is used for extract air filtration.BYPASS
The units are equipped with a bypass for summer ventilation (air cooling by the cool air from outside).
|CONTROL AND AUTOMATION
The KOMFORT ERV EC DB S14 units have an integrated control system with a wall-mounted control panel S14 with a LED indication. The units are equipped with a USB connector (Type B) and can be connected to a PC for configuring the advanced settings in a special software. The standard delivery set includes a 10 m cable for connection of the unit to the control panel. S14 automation functions:
Due to a low casing height the air handling units are a perfect solution for space-restricted installation above suspended ceilings. The unit mounting position must provide access for service maintenance.
