Robust Design for Large-Scale Heat Treatment at 1200°C
The GWDL-1200XL is a heavy-duty box-type resistance furnace with a 1m³ chamber, tailored for industrial-scale applications requiring high thermal uniformity and reliable long-duration operation. With a rated temperature of 1200°C, this furnace is equipped with vertical SiC heating elements on both sides of the chamber, offering rapid heating, precise control, and excellent thermal efficiency.
It is widely used in metal annealing, ceramic sintering, mold preheating, refractory material processing, and other industrial thermal treatments.
Key Features & Advantages
- Large Chamber Volume: 1000×1000×1000mm (1m³), suitable for bulky parts or batch processing
- Max Temp: 1200°C, with adjustable control from 80°C to 1200°C
