Heat Recovery System
Each pair of vents is joined by an aluminium canalization! The canalization can be lined by acoustic / thermal insulating material. An air/air heat exchanger made of aluminium is installed inside this canalization allowing hot wet air and fresh cold air to cross. The heat exchanger is designed in order to exploit as much as possible the exchange of heat of hot air flowing out of the kiln and transfer as much energy as possible to the fresh air flowing in.
