- Flexible heat source options, including electric, gas, or oil, ensure adaptability. The kiln's compact design and excellent sealing capabilities minimize material and heat loss
- Automatic temperature control with segmented settings and over-temperature alarms keeps the process stable. The internal wall's temperature distribution is uniform, with control precision within ±5°C, ensuring consistent results
- High heat transfer efficiency and superior insulation prevent excessive heat loss, keeping the kiln's surface temperature below 50°C
- Burners offer over 99% thermal efficiency, with single-pass heat efficiency exceeding 41%. The burner flame is powerful, whether columnar or flat, and ensures robust performance
- Emission control is a priority, with NOx concentration in exhaust gases kept below 100 mg/Nm³, ensuring compliance with environmental standards
- Calcining temperature is adjustable by controlling the kiln's speed and angle, with precise operations possible across a range from 350°C to 1050°C
