The characteristics of the Yashilin brand vacuum drying oven: the heating elements of the vacuum drying oven are arranged around the cylindrical working room, so that all parts of the working room are evenly heated. The working voltage of the component makes the temperature rise rate gradually reach the set temperature according to a predetermined proportion, and is constant near the set temperature point. The temperature error is less than ± 2 ℃ under normal pressure and vacuum.
Beijing Yashilin vacuum drying oven adopts digital display screen to display studio temperature or set temperature value, which is sensitive and easy to read. The studio is equipped with a pressure-resistant and heat-resistant glass window, which can observe the sample drying at any time. The whole machine has small size, light weight, energy saving, high thermal efficiency, flexible and convenient operation, etc. .
Precautions for use of vacuum drying oven:
1. The surface of the vacuum box shell must be in contact with.
2. The vacuum box should be used in an environment where the relative humidity is less than or equal to 85% RH, and there are no corrosive gases, strong vibration sources and strong electromagnetic fields around.
3. After repeated use of the vacuum drying box, the phenomenon that it cannot be evacuated will occur. At this time, the door seal should be replaced or the extension distance of the door buckle on the box body should be solved.
4. If the dry items are wet, it is better to add a filter between the vacuum box and the vacuum pump to prevent moisture from entering the vacuum pump and causing the vacuum pump to malfunction.
5. There is no explosion-proof, anti-corrosion and other treatments in the vacuum chamber studio, and it is not allowed to dry items that are easy, explosive, and prone to corrosive gases.
6. Except for maintenance, the left side box cover (except 6090 and 6210 models) cannot be disassembled to avoid damage to the electrical control system.
7. Vacuum drying oven should be kept clean frequently. Do not wipe the door glass with a reactive chemical solution, use a soft cotton cloth.
