Product application:
Vacuum ovens are widely used in biology, chemistry, chemical pharmaceuticals, medical and health, agricultural research, aviation research, satellite research, teaching research, lithium battery research and other industries, powder drying, product baking, vacuum temperature testing, etc., as well as disinfection and sterilization of various glass containers. They are particularly suitable for fast and efficient drying of heat-sensitive, easily decomposable, easily oxidizable substances and items with complex components.

Sample restrictions:
This test equipment is prohibited from testing samples of flammable, explosive, and volatile substances; testing of samples of corrosive substances, testing of biological storage, testing and storage of samples of strong electromagnetic radiation sources, etc.

Equipment functions:
1. The temperature, constant temperature time, vacuuming, nitrogen filling and other parameters of the vacuum oven are set through the touch screen, and the PLC automatically completes the following functions: vacuuming → standing → nitrogen filling (time control cycle is used for repeated cycles) → heating → constant temperature timing → nitrogen filling → end alarm;
2. It has functions such as over-temperature protection, overload protection, and phase loss protection. It can automatically stop heating, vacuuming and other functions in case of failure;
3. The equipment is easy to operate and can be easily mastered by workers without the need for professional personnel;
4. The equipment uses vacuum-specific control valves, vacuuming and nitrogen filling, which is highly efficient, saves personnel, and has good product performance;
5. The inner cavity of the equipment is welded with 5.0mm thick 304# stainless steel, which has strong corrosion resistance and strengthens vacuuming without deformation;
6. The outer box is made of 1.2mm thick Q235 cold-rolled steel plate, angle iron, channel steel and other materials; single cavity single door opening;
7. The equipment is equipped with movable casters and fixed foot cups;
8. It adopts high-quality stainless steel heating tube and external heating. The equipment undergoes temperature test and vacuum test before leaving the factory.

Inner dimensions	Width 850×Depth 800×Height 350mm; (three layers independently controlled)
Outer dimensions approx	Width 1700×Depth 1120×Height 2150mm including casters, subject to the actual product.
Interlayer	The single box is divided into 3 fixed layers, 50mm from the bottom and above the first layer, and equipped with 3 mesh plates, which can be pulled out.
Inner material	304# stainless steel industrial plate, 5.0mm thick, reinforced treatment, vacuuming without deformation.
Outer material	Q235 cold-rolled steel plate, 1.2mm thick standard plate, surface powder paint treatment.
Insulation material	High temperature resistant glass fiber rock wool, thermal insulation effect Good.
Sealing material	High temperature resistant silicone sealing strip.
Box structure	Integral type, the left part is upper, middle and lower product boxes, the right part is for electric control and vacuum pump installation, movable casters and adjustable fixed feet are installed at the bottom of the machine, which is convenient for movement and fixed position.
Timing function	The touch screen instrument has a built-in timing function, which stops heating, vacuum, nitrogen filling and other functions when the time is up, and alarms at the same time.
Current controller	Solid state relay SSR has no contact
Heating method	Thermal radiation convection, heating tube is installed outside the cavity.
