The EM-box can be connected to Nilan’s ventilation units. An EM- box enables heat recovery via the home’s cooker hood, utilising the heat generated from cooking.
When the cooker hood is switched off, the basic ventilation takes place via the hood. When more powerful extraction is needed, e.g. during cooking, a damper in the hood is opened. At the same time, the damper in the EM-box will regulate the air extraction from other rooms as a part of the basic ventilation, so that the primary air extraction takes place via the hood.
If a larger air volume is needed for the hood to provide effective extraction, the ventilation unit will increase the air volume. When the hood is switched off, ventilation will return to normal operation.
The EM-box can be placed above the extraction hood, or at any point between the aggregate and hood.
