The pipe bands are the real heart of our Tubix and Zoom ovens, the thermal “engine” that carries the heat to the baked products. Every tube constitutes a completely independent circuit, which contains demineralized water for about half of its volume that becomes steam during the heating process. A dense network of rings wraps the baking chambers and transmit heat by conduction to every single point. The pipe bands are cold-drawn, without welding and tested one by one according to the rules UNI 663/68 to grant high endurance.
