A variety of products, including alumina, iron ore pellets, rare earths, and metal powders can be produced in rotary tube furnaces. Any material that is difficult to heat through in a standard batch furnace, is a candidate for a rotary tube furnace.
These systems are also suitable for applications such as calcining, which necessitate the continuous flow of loose materials, as well as oxidation.
They are engineered to withstand high temperatures and provide comprehensive process control, resulting in high-quality products.
Each Deltech rotary tube furnace is uniquely tailored, allowing customization to the specific size, configuration, and features required to meet process needs. These features include those necessary for operation in hazardous environments.
Deltech complies with NFPA 86, UL 1203, and C1D2 (Groups A, B, C, D, and G) standards, in addition to ASME NQA-1: 2008 requirements. Furthermore, every Deltech control system is UL508A compliant, as certified by Intertek.
