The HRE-ERGO countercurrent heat exchanger is intended for

the HRU-ERGO heat recovery fans. can also be used with other brands.

 

The heat exchanger is made of a paper material with a high water content

Vapor permeability, good airtightness and good durability  for aging.

 

The distance between the cellulose fibers in the material allows this

free passage of water vapor molecules. Larger molecules, like

B. odors cannot pass through the heat exchanger.

 

This prevents contamination of the fresh air supplied indoors
