Unparalleled thermal efficiency

A heat exchanger of finely woven copper wire makes Fresh-r compact and efficient. Because copper conducts heat 1000x better than plastic, the material from which other heat exchangers are made.

Outgoing and incoming air never touch each other. Nonetheless, heat is transferred from one to the other. This takes place by means of extremely fine copper wire. Heat flows from warm to cold; with copper, this happens with a heat transfer coefficient of 400 W/mK. So the Fresh-r heat exchanger is extremely effective. The results of this is that the heat exchanger is compact, the fans use less energy, work as demand-driven and are quieter then other ventilators with heat exchangers. In this manner, the Fresh-r device sits in or on the exterior wall or in the window frame without bothering the residents.

Problem homes, with moisture, moulds, drafts, odours can be addressed while inhabited due to no-mess installation within a day and a half. During major maintenance or renovation, the Fresh-r makes one or more energy-label jumps possible, possibly in combination with closing gaps or simple installation.

Fresh-r is the only de-central ventilation with heat recovery certified by Passiefhuis; it complies with BENG standards and has a statement of equivalence for the (Dutch) Construction Act.
