The HRE-ERGO counter-flow heat exchanger is intended for
the HRU-ERGO heat recovery ventilators. The heat exchanger
is made with a paper material which features a high water
vapour permeability, good air tightness, and good resistance
to ageing.
The spacing between the cellulose fibres in the material allows
free passage of water vapour molecules. Larger molecules, like
those of odours, cannot pass through the heat exchanger. This
prevents the contamination of the fresh air supplied indoors.
