17 kinds of rotors are available for classical GL-21M,as continuous centrifugal rotor,titanium alloy rotor and aluminium alloy rotor.It is very popular in China market, because it is performance and diversified.
Features

• 4 types of continuous centrifugal rotor exsit in 17 rotors.
• Max. Speed is 21000RPM and Max.RCF is 47400xg.
• Microprocessor control,AC brushless motor,without carbon dust pollution,low noise and service life is long.
• Touch panel,LED display,programmable.
• 9 Acc profiles and 10 Dec profiles(NO.0 is free to stop),3 levels damping,centrifugal effect is best .
• The protective functions of electronic door interlock, imbalance, overtemperature and overspeed for safe operation.
• The automatic rotor identification system for avoiding over speed.
• The imported refrigerant is environmental and efficient.
• Acc and Dec time can be set freely by users,and RCF value  will be automatically calculated.Meanwhile temperature is controlled by dual ways of cooling and heating so as to  reach the best centrifugal effects.
