Fresh-r® On-The-Wall

Benefits of Fresh-r®

The Fresh-r In-The-Wall is a decentral ventilation unit with heat recovery that fits behind the waalpaper. It takes heat from
the stale air it expels and uses it to warm up the fresh air it brings in from outside.



Works below 0°

Also at sub zero temperatures the Fresh-r keeps ventilating when necessary. This makes it the only MVHR / HRV that works when it’s freezing.

Easy to install & maintain

There is no need for air ducts through you property. That save a lot of hassle in installation and maintenence. 

Uses only 6 Watt

On average Fresh-r only uses 6 Watt, because it only ventilates when the CO2 or humidity levels rise. That's about as much as a led light.

Gets rid of mould

Humidity is continuously measured. And Fresh-r makes sure it mould does not get a change. Our Passive House Certification is proof. 

Award winning technology

Because it is the cheapest ventilation with heat revovery per cubis meter for enrgy retrofits, according the International Passive House jury.

Optimal thermal efficiency

The copper core of heat exchanger is what makes the Fresh-r unique. Since copper conducts heat 1000 times better than plastic, which is the conventional conductive material in other heat exchangers, it is extremely effective.
