Sealed Rotary Vacuum Furnaces for Complex High-Efficiency 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:
Advanced 1200℃ vacuum atmosphere rotary furnace featuring high-purity quartz glass tube, vacuum sealing, and chlorine gas injection for corrosion-resistant, continuous high-temperature processing. Equipped with electromagnetic feeding and integrated vacuum control for efficient, low-leakage operation.
