With a three-zone independent heating system and adjustable rotation/tilt mechanism, the furnace ensures uniform heating, precise residence time control, and excellent process repeatability.
The GWL-KQGA-3 rotary atmosphere furnace is designed for continuous processing of powders, granules, and small bulk materials under controlled atmospheres. With a three-zone independent heating system and adjustable rotation/tilt mechanism, the furnace ensures uniform heating, precise residence time control, and excellent process repeatability.
It is widely used in catalyst calcination, ceramic powders, battery materials, and advanced inorganic processing, where a stable micro-positive pressure and atmosphere control are critical.
