Main Features:
- The company’s patented product square warehouse in situ vacuum freeze dryer, pre-freezing, drying
in situ completed, easy to operate, good drying effect.
- The drying chamber door is made of ACRYLIC material, which is colorless, transparen and can observe
the whole process of freeze-drying.
- The inflatable (drainage) valve adopts safety diaphragm valve, which can connect inert gas source,
fill inert gas after drying, and prolong the shelf life of materials.
- Specialized gas diversion technology, uniform cold trap ice capture ability.
- International well-known brand compressor, high efficiency and energy saving, lon service life,
low noise.
- The patented technology of partition and the fuzzy control technology of partition temperature
have the advantages of small temperature difference of shelf, high precision of temperature control
and even drying effect.
- Powerful sensor calibration function ensures long-term use of measurement accuracy.
- 7-inch real-color industry embedded touch screen + SH-HPSC-11 modular controller, hig control
accuracy, stable and reliable performance.
- The specially designed FD-PILOT control system can preserve hundreds of formulations, each of
which contains 36 temperature control sections, so as to improve the process optimization rate.
- Intelligent data recording system can record and display the temperature curve of cold trap, sample
temperature curve and vacuum curve in real time. The derived data can be browsed and printed by
computer and operated in a variety of ways to facilitate proces optimization and drying effect
verification.
- Flexible manual + automatic control mode, manual for exploring process, automatic fo batch
production.
- Real-time alarm display and historical alarm inquiry functions facilitate fault diagnosis and
equipment maintenance.
- User level and password can be set, and operation management can be decentralized.
