Ventilation system D

Fresh air throughout the house without wasting energy!

How does System D ventilation work?

The heat recovery unit or type D ventilation system uses the temperature of the outgoing air to change that of the incoming air. This happens in the heat exchanger. No less than 95% of the energy can be reused

At the same time, this system maintains the humidity level of the air thanks to an enthalpy exchanger. Your home stays warm in winter and cool in summer.
