EM-box is for anyone who wants passive heat recovery via the homes range hood.
The EM-box is an accessory item that can be connected to Nilan's domestic system. With an EM-box the range hood can be used for more than just extraction. In this way the EM-box uses the range hood for both basic ventilation and range hood extraction and concurrently it recovers the energy in the discharge air.
In some homes the space is not optimal for an installation of an EM-box. In these cases a range hood filter box can be used instead. The range hood filter box takes up less space and can be located adjacent to the range hood.
EM-box is available as a ceiling model that can be installed on either the left or right side of the range hood.
Use
The EM-box can be connected to Nilan’s ventilation units. An EMbox 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.
Range hood filter box
If the EM box cannot be optimally located, a range hood
filter box can be used instead.
