Green energy in industrial tunnel baking ovens

By exchanging gas burners with electrical heaters in tunnel ovens the bakery becomes more climate friendly.

One gas burner is emitting up to 45kgs. CO2 per hour and it blows out up to 10KWH of energy in the chimney.

By substituting the gas burner with electrical heaters, these emission can be eliminated to ZERO!

Many bakeries have ovens with 3-4 or more burners in one tunnel oven line, and many bakeries have multiple oven lines in their bakeries.

Government laws and regulations may very soon force the bakeries to do something drastically.

With the SENIUS Electrical Heater Insert a solution is simple and easy to implement.
