The rotor which is constructed like a honeycomb, rotates non-stop between the stream of hot exhaust air and the cold intake air.
The rotor is warmed up in the stream of exhaust air and transfers the heat to the stream of incoming cold air.
Up to 75% of the heat contained in the exhaust air can be recovered in this way.
