This oven line is realized in single block module versions of 1 chamber or 2 chambers. The use of special materials with high insulation capacity, the result of the experience of many years in the field of professional pizzerias, determine an optimal thermal efficiency and therefore low current consumptions. The baking chambers are in stainless steel. The door is realized in stainless steel without any glasses. Without any internal lights. The front and the external panels are realized in stainless steel. Every oven is equipped with an electromechanical (B1-B11) or electronic (B1E) timer on the main board. The oven has a chimney flue which, if connected to outdoor, allows the smoke discharge. The temperature is chosen by electromechanical thermostats (B1 and B11). The B1E oven is equipped with an advanced controlling electronic.
