Features:
- AV motor of variable frequency and high toque,free from contamination caused by carbon dust,which helps to prolong the service life.
- Imported variable frequency drive system and automatic control system to ensure steady and reliable operation.
- France-based Tecumseh’s compressor unit is used for the refrigeration system which allows free temperature adjustment and achieves high-precision temperature controls and reduced noise.
- Maximum capacity 6x500ml,Maximum rotation speed 21000rpm.
- Multiple protections such as overheat,hypervelocity,electronic locking and imbalance.
- Metallic structure with a stainless steel cavity,hence strong and durable.
- Intelligent interface featured by a TFT true-color LCD wide-screen touch monitor,micro-computer control and simultaneous indication of both the set parameters and operation one.
- With 16 operation programs to be set by the user and the control parameters of the rotor to be modified at any time.
- Operations can be programmed,10 levels of speed-up and speed-down time limits for the user to choose freely.
- Can indicate the ascending and declining curves of the rotor ,the centrifugal integral curves and the temperature curves.
