High-Temperature Furnaces

Ultra-high-temperature thermal processing is challenging, with stringent requirements placed on furnace materials to withstand extreme hot zones and harsh chemistries. Most high-temperature furnaces require inert atmospheres or even vacuum conditions to heat materials up to 2000 degrees Celsius. That is what sets Deltech’s ultra-high-temperature furnaces apart.

We are a leading high-temperature furnace company, and one of the only US suppliers of thermal processing equipment offering high–temperature furnaces for in-air processes of up to 2000 degrees Celsius. Our high-quality, efficient design is also very economical compared to vacuum furnaces. 

When you can’t accomplish your research and development (R&D) goals without sustained operation at 2000 degrees Celsius, consider our specialty furnaces. We specialize in custom builds based on your unique requirements, so you can be assured that your new system will function to the highest performance parameters needed.
