1. Precise Temperature Control & Flexible Curves Smart temperature controller supports PID/APID/MPT regulation with ±1℃ accuracy. 50-segment program control allows multiple curves to be stored and called on demand, delivering smooth, overshoot-free heating/cooling ramps.
2. Fast Heating & Even Distribution Three-side heating (two sides + bottom) with high-temperature alloy resistance wire achieves a max heating rate of 40℃/min for uniform temperature distribution.
3. Excellent Insulation & Safe Surface Vacuum-formed high-purity alumina lightweight lining offers low heat storage and resistance to thermal shock without cracking or shedding. Shell temperature stays below 45℃, so the surface remains cool to the touch even after long operation.
4. Comprehensive Safety Protection Integrated modular dual-loop control and protection covers over-temperature, over-current, over-voltage, phase loss and soft start. The main heating circuit automatically cuts off when the door opens at high temperature, eliminating electric shock risk.
5. Robust Structure & Long Service Life Air-cooled double-layer carbon steel shell circulates cool air to protect the heating element terminals from high-temperature oxidation. The 180° side-opening door with elastic latch ensures reliable sealing and self-adapts to thermal expansion.
6. Simple & User-Friendly Operation Intuitive touchscreen display paired with dual knobs (main power / heating power) for clear operation. Auto-tuning and self-learning functions eliminate complex setup — ready to use out of the box.
