Vacuum Rotary Furnace

High-Purity Vacuum Rotary Furnaces for Cost Saving and Fully Customized Powder Processing

GWDLTHERMO vacuum rotary furnaces are specifically designed to support thermal processing of ultra-high-purity powders up to 5N grade (99.999%), such as electronic-grade quartz, rare earths, and semiconductor materials. The sealed rotary tube design ensures exceptional atmosphere integrity, minimizing contamination and reducing the loss of high-cost gases like hydrogen or HCl during chlorination or reduction processes.

With an intelligent integrated control system, the furnace synchronizes drum rotation, temperature zoning, gas flow, and feeding/discharge, ensuring stable reaction conditions and optimized throughput.

We specialize in complex, process-driven customizations:

• Multi-stage thermal zoning
• Long residence times
• Special drum linings or sealing structures
• Low oxygen design for reactive materials
• Continuous or batch feeding systems
