Blauberg BLAUBOX DW 2300-4 Pro

Ventilation units for efficient supply ventilation in various premises. Controllable air supply, heating and filtration. Compatible with 400x200 up to 700x400 mm rectangular air ducts.

The casing is made of double-skinned aluzinc panels, internally filled with 50 mm mineral wool layer for heat and sound insulation. The casing has fixing brackets with vibration absorbing connectors for easy installation. The hinged casing panel ensures easy access to the internals for cleaning, filter replacement and other maintenance operations.

Asynchronous external rotor motor and centrifugal high-pressure impeller with backward curved blades is used for air supply. Integrated motor overheating protection with automatic restart. Dynamically balanced impeller. Equipped with ball bearings for longer service life. Reliable and quiet operation.

The units are equipped with a water (glycol) heater for operation during cold seasons at low outside temperature. The air temperature sensor downstream of the water heater and the return heat medium sensor ensure freezing protection of the water heater. If any of these sensors detects a temperature point below the set minimum value, the signal is sent automatically to the control unit to troubleshoot cooling.

The built-in G4 supply filter provides air filtration. Optionally a F7 filter may be installed for efficient filtration.

The unit is suitable for mounting on the floor, ceiling mounting or wall mounting with fixing brackets in any mounting position except for the vertical one with air flow downwards. The correct mounted unit must provide free access to the hinged panel for servicing and filter replacement.

The units incorporate an integrated control system with a wall-mounted control panel and LCD display. The standard delivery set includes a 10 m cable for connection of the unit and the control panel. Control panel functions:

• Activating/deactivating the unit.
• Setting low, medium and high speeds for the supply fan. Air flow control.
• Setting and maintaining of indoor air temperature.
• Display of the indoor air temperature.
• Supply filter clogging control according to the pressostat.
• Alarm indication.

• Control of the supply air damper actuator (separate order).
• Smooth rotation speed control of the fan (3 ~ 400 V, 50 Hz).
• Water heater control.
• Generation of the activation signal for the exhaust fan if available in the system.
• Shutdown of the unit on signal from the fire alarm panel.
• Control of the cooler with respect to the set indoor air temperature (separate order).
