Vacuum Drying Oven with Digital Controller and Gauge for Lab Heating and Drying Applications

This digital convection oven is designed for precision drying and heating applications in laboratories, medical settings, electronics, and agriculture. It features PID temperature control with a range of 50-280°C, adjustable airflow, and uniform hot-air circulation to enhance productivity through rapid processing while maintaining consistent quality. Key features include a microcomputer intelligent temperature controller with PID control mode for ease of use, overtemperature alarm, self-optimization function, and temperature calibration. It is equipped with high-quality stainless steel electric heating tubes for long service life at high temperatures, two removable shelves for easy cleaning and replacement, and a large double-layer tempered glass observation window for convenient monitoring. Specifications: Coating materials include galvanized liner and stainless steel liner, voltage options of 110V/110V, temperature fluctuation of ±1°C, and a time range of 1-9999 minutes. The PID function allows for accurate temperature control settings and over-temperature alarm. Available in three sizes: 16 liters with inner tank size 25*25*25cm, power 500W, appearance size 54*37*43cm, net weight 15kg, and 4 layers with 5cm spacing; 43 liters with inner tank size 35*35*35cm, power 800W, appearance size 63*46*47cm, net weight 23kg, and 4 layers with 7cm spacing; 70 liters with inner tank size 45*35*45cm, power 2000W, appearance size 75*46*61cm, net weight 32kg, and 4 layers with 9cm spacing. The package includes one constant temperature drying oven, two separators, and one manual.

• Precision Temperature Control: Digital PID controller maintains 50-280°C with ±1°C accuracy, featuring a clear LCD display for set and real-time temperature, timer, wind speed, and heating status. Includes auto-tuning, over-temperature alarm, and calibration for reliable performance.
• Uniform Heating Technology: Dual-channel hot air circulation and high-temperature fans ensure efficient drying and even heat distribution. Adjustable fan speed prevents hotspots, while a synthetic silicone sealing strip enhances airtightness to minimize heat loss and maintain consistent temperatures.
• Industrial-Grade Construction: Built with a durable liner and cold-rolled steel shell, this unit features a thickened insulation layer to reduce heat dissipation and improve energy efficiency. Reinforced door hinges and a double-layer tempered glass window provide safety and easy monitoring.
• Safety and Efficiency Features: Equipped with overheat protection, reinforced door hinges, and a double-layer tempered glass observation window for secure operation. Optional adjustable trays support up to 33 lbs each, and ventilation holes facilitate efficient moisture discharge with a low-noise fan design.
• Versatile Applications: Suitable for various industries, including industrial manufacturing for coating curing and heat treatment, medical research for sterilization and sample preservation, agricultural processing for dehydration, laboratory testing, and maintenance workshops for annealing and tool care.
