Deltech Vertical Furnaces

Deltech ultra high temperature furnaces are capable of operation at 2000 degrees Celsius in air. This distinguishes these furnaces from those that require vacuum operation. Our high quality, efficient design is also very economical when compared to vacuum furnaces. When you can’t accomplish your R&D goals without sustained operation at 2000 degrees Celsius, consider these specialty furnaces.
