Custom Small Scale Tunnel Kilns

Changing from electric fired to gas fired furnaces can result in significant changes in product outcomes.  A custom Deltech tunnel kiln offers a great way to scale up while duplicating the conditions found in resistance heated batch furnaces. Depending on your process parameters, a tunnel kiln might be preferable to a production size “top hat”, bottom loader, or front load furnace, while still maintaining the rapid heating and cooling and exceptional temperature uniformity characteristic of Deltech non-continuous furnaces. Check out the list below of many of the optional features available for your custom designed and build tunnel kiln.
