Heat recovery units, or heat exchangers, are mechanical ventilation systems useful for avoiding the dispersion of the heat produced by heating systems or of the cool produced by air conditioners: in this way it will no longer be necessary to open the windows to change the air!

During the summer, the hot air from outside is conveyed into the recuperator and is cooled thanks to the heat exchange with the "stale" air already present in the room. During the winter, on the other hand, the cold air that arrives from outside is heated according to the same process. Thanks to this system, a feeling of well-being remains through a continuous and controlled exchange of air in closed environments, not to mention substantial energy savings, as the recuperator does not require much energy to operate.
