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 with high-temperature fans enhances drying efficiency and ensures 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 significantly reduces heat dissipation, improving energy efficiency. Reinforced door hinges and a double-layer tempered glass window ensure safe operation and convenient monitoring. Safety and Efficiency: Includes overheat protection, reinforced door hinges, and a double-layer tempered glass observation window for safe use and easy monitoring. Optional adjustable trays support up to 33 lbs each, and ventilation holes allow for efficient moisture discharge. A low-noise fan design ensures quiet operation. 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 and biological sample preservation, agricultural processing for grain dehydration, laboratory use for material resistance testing, and maintenance workshops for metal parts annealing.
