All the technology you need to keep your air healthy fits behind the wallpaper
The Fresh-r consists of a box structure with two ventilators blowing in opposite directions. Between these ventilators is the most efficient air-to-air heat exchanger ever developed. It keeps recovering heat at maximum efficiency even in temperatures below zero. This makes it the only ventilation with heat recovery that simply keeps working – i.e. without bypass or electrical heating – in freezing temperatures. It is demand-driven by CO2 and H2O; this means that it works only when necessary.
