Northvent ECO A50-4 Pro

0.00

Single-room heat recovery units with Wi-Fi control. Maximum air capacity up to 50 m³/h.

Description

FEATURES
Arrangement of efficient energy-saving supply and exhaust single-room ventilation in flats, houses, cottages, social and commercial premises. Air purification with optional F8 filter PM2.5 > 99 %. Protection from outdoor noise. Reducing heat losses caused by ventilation due to heat recovery. Humidity balance and regulated air exchange create individually controlled microclimate.
DESIGN
UNIT OPERATING LOGIC IN WINTER PERIOD
Warm stale air is extracted from the premise, flows through the ceramic regenerator and transfers its heat energy and moisture to it. As the ceramic regenerator gets warmed up, the unit switches to the supply mode. Clean cold intake air flows through the regenerator and absorbs accumulated heat and humidity. When the ceramic regenerator is cooled down, the unit switches to the extract air mode.
CONTROL
Control of the unit operation mode is performed by means of the sensor control panel.
One control panel with sensor buttons can control up to two units. Low voltage (12 V) power supply between control panel and Eco units.
MOUNTING
The unit is designed for through-the-wall installation inside a prepared hole in an outer wall of the building. One unit is able to ventilate a room up to 25 m2. For bigger rooms two or more units must be installed.
