TOP
1. The shelves incorporate our innovative technology , utilizing a circulating heat transfer fluid within them. This unique design allows for in-place refrigeration or heating, resulting in uniform temperature distribution and easy temperature control. As a result, these shelves serve as highly efficient conductors.
2. Our independently researched and developed PLC system enables seamless automatic control or semi-automation functionalities.
3. Equipped with:
1) A 7" touch screen:
- Record and present real-time data. Get an at-a-glance view of live readings, including vacuum pressure, cold trap temperature, and material and shelf temperatures. These readings collectively construct the freeze-drying curve;
- Data-saving frequency: every minute;
- Efficiently capture and continuously monitor comprehensive data on the material and the freeze dryer’soperational status;
- Off-linedata is available for analysis, printing, and storage;
2) USB ports.
4. Real-time monitoring of vacuum pressure is implemented to safeguard the integrity of the vacuum system. If the vacuum pressure fails to reach the designated setpoint within the stipulated timeframe, an automatic shutdown of the vacuum pump is triggered. Subsequently, the solenoid valve is activated to allow air ingress, thereby maintaining the shelves’temperature at a normal level under atmospheric pressure conditions. The vacuum pressure chamber functions like an Ultra-Low Temperature (ULT) freezer, offering enhanced protection for the samples.
5. The refrigeration system is bolstered by two hermetic compressors, which are interconnected, with one compressor responsible for refrigerating the other. This compressor unit utilizes environmentally friendly refrigerants that adhere to international safety standards. These combined features facilitate rapid refrigeration. The cooling system is stable,with low vibration and low noise.
6. The compressor incorporates a restart delay mechanism, and an integrated thermal overload module is employed to safeguard the freeze-dryer from overheating.
7. A distinctive design incorporates a heat transfer mechanism, making the shelves achieve a higher level of temperature control accuracy.
8. It features an independent compartment design for the material chamber and the cold trap chamber, which accelerates the sublimation rate of the product while increasing the ice-holding capacity.
9. Access the cumulative operating hours of the vacuum pump, serving as a reliable indicator to determine the optimal timing for changing the vacuum pump oil, beneficial to extend the equipment’s service life.
10. The cold trap has mechanisms for spraying, thus immersing to remove frost.
11. Comprehensive information, including user login history, activities, freeze-drying data/curves, and alarm records, is meticulously tracked and recorded. Users can directly export freeze-drying curves and generate datasheets in PDF format.
12. The freeze-dryer can store up to 50 recipes, which can be customized with different names. Each recipe offers 36 temperature control stages, and individual time settings can be configured for each stage. The freeze-dryer intelligently waits until the specified time reaches its setpoint before initiating the countdown. During any given stage, it allows for real-time data modification, and the system automatically adjusts the time spent on sublimation based on the changes made.
