OTF-1100X-R-15-AF Large-Capacity 1100°C Rotary Tube Furnace with 3 Independent Heating Zones and Automatic Powder Feeding for Powder CVD Applications
The OTF-1100X-R-15-AF is engineered to meet the demands of large-scale powder synthesis and heat treatment, particularly for inorganic compounds and battery electrode materials. Its design incorporates a high-purity quartz processing tube with a substantial internal volume, enabling powder loading of approximately 30 liters. This capacity supports continuous processing at temperatures ranging from 400°C to 1000°C, with short-term operation up to 1100°C.
To ensure uniform heat treatment and mixing, the furnace employs a gear-driven rotating tube mechanism combined with internal stirring blades welded inside the quartz tube. The furnace tilt angle is electrically adjustable between 0 and 15 degrees, facilitating directional powder movement and collection. Three independently controlled heating zones span a total length of about 1000 mm, with a central 600 mm zone maintaining temperature uniformity within ±5°C when all zones are set identically.
