The air-cooled vacuum drying oven (also known as an air-cooled vacuum drying oven with cooling function) is a new generation of intelligent vacuum equipment strategically developed by our company to lead high-end manufacturing and precision scientific research processes. It surpasses the performance limitations of traditional equipment, integrating heating, constant temperature control, timing, vacuum control, pressure regulation, and the core function of rapid cooling into a single unit. This achieves a complete process from high-temperature treatment to rapid cooling, significantly improving production efficiency and process consistency. The equipment adheres to a modular design concept, possessing powerful functional expandability. Advanced modules such as nitrogen protection, high-efficiency oil fume filtration, multi-segment programmed temperature control, and programmed pressure control can be flexibly added according to customers' specific process requirements to meet complex and demanding application scenarios. Its reliability and advanced features have led to its widespread application, making it an ideal device for driving technological innovation and quality upgrades.

⑦ Sealing Strip: Equipped with a self-developed molded silicone rubber sealing ring, with a circumferential convex line structure and a unique active vacuum breaking sealing technology. It instantly forms a channel during pressure release, greatly improving vacuum breaking efficiency and ensuring that the door can be easily opened after pressure release;
⑧ Mesh Shelves: Removable mesh shelf design greatly improves the utilization and flexibility of the working chamber space, while making cleaning and maintenance extremely simple and efficient;
⑨ Insulation Layer: 100mm thick high-purity ceramic fiber cotton (Al₂O₃) is filled between the shell and the working chamber, providing excellent thermal insulation, greatly reducing heat loss, ensuring constant temperature stability, and achieving high energy efficiency;
⑩ Emergency Pressure Relief Valve: Classic stainless steel pressure relief valve, easy and sensitive to operate, and reliably sealed.
① Equipped with a 7-inch intelligent touchscreen controller, serving as the control center of the equipment, it makes complex process management intuitive and efficient. The controller provides precise setting of core parameters such as temperature, constant temperature time, heating rate, vacuum degree, and constant pressure time, and can execute advanced commands such as automatic pressure relief and automatic inert gas filling, fully meeting the needs of precision processes;
② Diverse timing methods: 1. The timing unit can be freely switched between minutes and hours; 2. Two timing modes: timing from power-on and timing after reaching constant temperature;
③ Supports complex program programming of 100 groups, each with 100 segments. Users can preset and store complete process curves. During use, simply recall the program and click run to easily achieve automated operation for batch production, greatly improving process consistency and repeatability;
④ In terms of data security and management, the system features a three-level permission management system (administrator, engineer, operator), effectively preventing unauthorized operations and ensuring the security of critical process parameters and data, preventing the leakage of confidential process parameters;
⑤ Operational safety: The controller has built-in over-temperature alarm and automatic heating cut-off functions, providing double protection to ensure a foolproof experimental process;
⑥ Power failure recovery function: It has intelligent timed shutdown and automatic power-on recovery functions, seamlessly connecting to preset processes and ensuring the continuity of the process and the integrity of the data.
⑦ Long-term parameter memory and high-precision temperature deviation correction, combined with advanced self-tuning technology, can quickly and accurately match the best control parameters, significantly improving temperature control accuracy and equipment response speed;
⑧ Multiple modes can be freely switched: fixed value mode/timed mode switching.
