Consisting of highly efficient fans, developed by Chatron, these units have an extremely low energy consumption, so can be powered from photovoltaic solar panels, running 100% independent from the mains.

It is the more efficient energy recovery unit in the world.
The power required for full operation is 40 W.
Operates at 12 V and can be powered from one solar photovoltaic panel.
It respectively allows an incoming and outgoing air flow of 1.250 m3/h efficiency could reach 90% of energy recovered.

Inside of the unit there is a the cross flow exchanger , which allows a high exhange of heat or cold, between the indoor and outdoor air, offering a higher energy saving.
