Driven by frequency conversion motor, controlled by microprocessor. Digital display, with 9 Acc/Dec Rates and the self-diagnostic system for 8 problems.

Display speed, temp., time, etc. The specific parameters stored can be used repeatedly and accurately.

Provided with protective means for imbalance, over temperature, over speed. Imported compressor with technology of pair of way by refrigerating or heating to meet the temperature control-accuracy, less noisily.

Be applied to the fields of hospitals, central blood stations, bio-products, bio-pharmaceuticals, agricultural science, scientific research, and the separation of particles of different density in solution.
