• Precision Temperature Control: Digital PID controller maintains 50-280°C with ±1°C accuracy, indoor temperature from 10-300°C. The digital LCD display clearly shows set temperature, real-time temperature, timer, wind speed, and heating status. Features timer, auto-tuning, over-temperature alarm, and calibration for reliable performance.
• Uniform Heating Technology: Dual-channel hot air circulation and high-temperature fans enhance drying efficiency and ensure uniform heat distribution within the chamber. Adjustable fan speed prevents hotspots, while a synthetic silicone sealing strip provides excellent airtightness to minimize heat loss and maintain consistent internal temperatures.
• Industrial-Grade Construction: Features a stainless steel or galvanized liner option with a cold-rolled steel shell. A thickened insulation layer reduces heat dissipation, improving energy efficiency. Reinforced door hinges and a double-layer tempered glass window ensure safety and convenient monitoring.
• Safety and Efficiency: Includes overheat protection, reinforced door hinges, and a double-layer tempered glass observation window for safe operation. Optional adjustable trays support up to 33 lbs each, and ventilation holes allow efficient moisture discharge. A low-noise fan design ensures quiet use.
• Multi-Industry Application: Suitable for various scenarios such as industrial manufacturing for electronic coating curing and automotive parts heat treatment, medical research for instrument sterilization, agricultural processing for grain dehydration, laboratory use for material resistance testing, and maintenance workshops for metal parts annealing.
