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:
Tilting and Rotating Vacuum Atmosphere Tube Furnace: Double-walled air-cooled shell, optional 10-type multi-atmosphere system, integrated vacuum quenching, full-process material heat treatment. Applications: powder materials, ceramics, metallurgy, electronics, glass, chemicals, machinery, refractories, new materials, etc.
Sealed quartz tube rotary furnace: high-purity quartz glass or corundum 99 ceramic tubes, integrating precise temp control (±1℃), multi-atmosphere treatment, intelligent rotation. Designed for high-end powder heat treatment. Excellent sealing, ideal for research institutes/enterprises in material R&D and production.
