Fresh-r is like a breathing window
It keeps warm air in and fresh at the same time. In the summer it works the other way around. Then, cool air is kept inside. The Fresh-r fits into the wall or window frame and doesn’t take up space.
The Fresh-r can also be placed against the wall, requiring only two 160 mm holes. During renovation, the front surface of the cavity wall can be sawn out and the entire unit then sits in the cavity. The unit is built-in beforehand in prefab walls or frames.
Even when it’s freezing outside, Fresh-r continues to work well. This keeps heat demand much lower, allowing for the installation of a smaller heat pump or less infrared heating on the road toward heating without gas and energy neutrality.
