Tunnel Oven

Hasborg tunnel kilns are high-quality convection ovens with very high thermal efficiency. These are durable ovens, made of thick stainless steel sheets. Depending on the length of a given oven, they are divided into sections (2, 3 or 4).



- Digital control panel

Air circulation in the chamber
Circulation of heated air in the chamber and dry (fresh) air and removal of moist air from the baking chamber. Thanks to the appropriate shaping of the air circulation in particular areas of the oven we obtain high quality of the final product.


Indirect convection furnace with tubular heat exchanger powered by gas. The applied solutions ensure full control of parameters such as temperature, up/down airflow ratio, air exchange. All parameters are set from the control panel by means of servo drives. The control of air humidity level in the burner chamber significantly extends the furnace life.
