Dual flow ventilation

  • Dual flow:  

    Dual flow ventilation allows to renew indoor air with flow rates fixed in advance, which correspond to needs of your home. With its heat exchanger.

    Advantages of dual flow ventilaton


         In a house, warm air tends to accumulate on ceiling since a hot fluid has a lower density than a cold fluid. In case of natural ventilation, this hot air is lost by escaping during ventilation. Same with a simple flow ventilation, which ejects the heat at the same time as the bad air.

    Dual flow ventilation use  hot inside air to preheating cold input air. Thank to this system, we loseing less heat.
