Overview
The DHG-9140 electric thermostatic blast drying oven is a laboratory equipment with a volume of 140 liters. The shell is welded with good steel plate and the surface is lame plated, and the inner chamber is lame plated with high temperature silver powder paint. The box door is equipped with a double-decked Glass observation window, and the studio and the box door are insulated by heat-resistant silicone rubber or asbestos rope sealing. The power switch, temperature control instrument and other operating parts are concentrated in the front of the box body for easy operation.
Features
1. Using microcomputer smart digital temperature control instrument, with self-tuning function, high temperature control accuracy.
2. Adopt a progressive heating method to effectively suppress temperature overshoot.
3. Set the temperature with a protective device and a tracking alarm function.
4. The box is equipped with a fan and a suitable air duct structure to ensure uniform temperature.
5. Timer Range, up to 1-9999 minutes.
Principle
The heating thermostatic system of the drying oven consists of an electric heater, a temperature controller, a fan and an air duct structure. After the power is turned on, the fan works at the same time, and the heat generated by the electric heater is discharged through the air duct, flows through the work room to be dried and then sucked in by the fan.
Applications
Applicable to laboratory, scientific research, teaching, industrial production and other fields of drying, baking, heat treatment, etc.
Steps
1. Place the drying oven in a stable and well ventilated position.
2. Connect the 220V 50Hz power supply.
3. Set the required temperature (range RT + 10~ 300 ° C) and timing time (1-9999min) through the temperature controller at the front of the box.
4. Turn on the power switch, and the fan and heating system start working.
5. After the work is completed, turn off the power and remove the items.
Notice
Equipment should be placed in a smooth, well-ventilated environment.
• Do not place flammable, explosive, volatile and corrosion items in the box.
• When taking and placing items, please be careful to avoid burns.
• Regularly check whether the sealing strip of the box door is in good condition to ensure the sealing performance.
• Please disconnect the power supply when cleaning, wipe with a soft cloth, and avoid the use of corrosion cleaners.
