Features
Improved Accel/Decel Time - Max. 3 times Faster
himac original technology "PWM motor control"
- PWM (pulse width modulation) motor control has realized substantial reduction in acceleration and deceleration time.
- Acceleration and deceleration time of CR-G‡V Series with large capacity rotor has improved max. 3 times faster than the one of our former models of high-speed refrigerated centrifuge.
- Reducing running time contributes to energy saving and reducing CO2
Energy Saving
Acceleration and Running at set speed
- Reduced electricity consumption substantially by IGBT inverter
Deceleration
- himac regenerative braking system re-generates max.40% electricity used for acceleration and running.
- It reduces heat radiation into the room and is high efficient for energy saving.
Former models : Kinetic Energy Heat radiation into the room
New System : Kinetic Energy Regenerated to electricity and reused
Self-Locking Rotor System
-
- Hitachi Koki is a pioneer to introduce "Self-Locking Rotor System" in Centrifuges.
- Just placing a rotor onto the drive shaft
- No need to fix the rotor by screw or push the button to lock or unlock the rotor.
- Automatic rotor identification (PAT.)
- Optimized running condition is automatically adjusted.
(such as compensating for air friction and implement temperature control)

Advanced Technology
Non-Contact Imbalance Protection (PAT.)
- Continuous measurement of oscillation over the entire rpm range
- The system immediately detects abnormal vibrations and stops rotation.
Actual Control of Net Run-Time(PAT.)
- The timer starts when the set speed is attained by himac original actual run timer function.
- Enables to obtain high-reproducibility separation.
Pre-cooling Chamber (PAT.)
- Maintaining temperature inside chamber room at low temperature with preventing from icing, in order to reach target temperature shortly
