Healthy air guaranteed – with DER VentoTherm Twist!

The ventilation system with heat recovery is integrated in the window. It automatically provides living and working spaces with pleasant, pre-heated fresh air while the window is closed. This increases wellbeing while reducing energy costs.

Intelligent sensors detect room conditions, such as CO2 levels in the air, and regulate the air flow.

If required, an F7 external air filter offers additional protection against insects and pollen, so that allergy sufferers in particular can breathe easy.
