Vacuum Drying Oven — Multiple Chambers
Vacuum Drying Test Oven
Application Overview
This product is suitable for heat treatment under vacuum during electronics production, including degassing, dehydration, curing and drying after cleaning. It is widely used for vacuum drying in the production of lithium-ion batteries, LED optoelectronic components, crystal oscillators and other electronic products. It supports simultaneous comparison of experiments under different conditions, saving testing time and improving efficiency.
Product Features
- The stainless-steel sheet chamber ensures durability. An all-SUS304 stainless-steel outer housing is optional for easy cleaning;
- The rectangular vacuum chamber provides a large usable volume and efficient use of space;
- A resilient double-layer tempered-glass door provides a clear view of objects inside the chamber;
- Door-closing tightness is adjustable, and a one-piece molded synthetic silicone-rubber door seal ensures a high vacuum inside the chamber;
- An independent temperature-limit alarm system automatically interrupts operation if the limit is exceeded, ensuring safe experiments without accidents (optional);
- Each chamber tier can independently heat, evacuate and admit nitrogen without interfering with the others;
- A low-noise dedicated branded vacuum pump provides stable, reliable vacuum control (B series);
- Additional shelves and LED lighting can be fitted (optional).
Direct Shelf Heating and Control
- Each shelf has its own temperature sensor and control circuit for precise response when drying different loads. Temperature settings, monitoring and timing can be displayed and controlled independently for each shelf in use. Heating elements are positioned directly underneath the shelves to avoid temperature deviations, providing more precise measurement and stable control. Heating and operating times are reduced by more than 50% compared with heating wrapped around the chamber;
Programmable Control (Optional)
- Programmable operation allows heating, vacuum-hold and nitrogen-hold times to be set according to process requirements, ensuring consistent baking between batches and reducing product-to-product baking variation;
