Everything for a healthy indoor climate
From advice to installation, maintenance and service. All under one roof.
We install only Zehnder Q + Renson Flux.
Both come with a built-in humidity sensor as standard. Renson also offers side-connections and a flat version for low ceiling heights. Options like an ERV exchanger (extra humidity recovery) can be added externally to both systems.
