The Henry Group's Indirect Gas or Oil Fired Tunnel Oven is designed for baking a vast variety of products in pans, as well as products baked directly on the hearth.Automatic natural gas or oil burners fire into a combustion chamber which is completely lined with high quality, high temperature Inconel and 310 stainless steel. The heat exchanger system keeps combustion by-products outside the baking chamber allowing products to bake in heated ambient air. The mesh hearth allows complete air circulation and uniform pattern on bottom of products. Pre-assembled and insulated exterior panels along with modular design concepts allow for faster and easier installation. Also available with electric heating elements or propane gas burners.
