CR22N Refrigerated Centrifuges

Easy operation with color touch-sensitive LCD

Color touch-sensitive LCD and GUI (graphic user interface) with high contrast against back screen in black color enables users to easily operate the system or select various menus and functions by touching the icon on the display. Of course, operation status is identified at a glance by intelligible screen design.

Self-locking rotor system

• himac original “self-locking rotor system” is the most simple system to place the rotor onto the drive shaft. You just simply place the rotor on the drive shaft and that’s all. The rotor is locked by centrifugal force automatically. You do not need to fix the rotor by screw or push the button to lock or unlock the rotor like other models available in the markets.

  

All standard rotors maintained at 4 ℃

CR22N is the 1st model equips inverter refrigerator system in this class*. The inverter refrigerator system provides you high efficient temperature control of the rotor and less electricity consumption is anticipated. Also the refrigeration capacity was improved, so now all standard rotors can be maintained at 4 ℃ at their maximum speed without vacuum system. (under room temperature at 25 ℃) (There are some exceptions about made-to-order rotors.) In addition, invertor refrigerator system has reduced operating sound, because there is no start-up sound of conventional refrigerator system.

Non-contact imbalance detection system

The himac original imbalance sensor continuously measures oscillation over the entire rpm range. The system immediately detects abnormal vibrations caused by the imbalance of the rotor and stops the rotation of the rotor automatically.

Economy mode (automatic standby function)

• CR22N has Economy mode (automatic standby function) in it. If the display is not touched over the set wait time, the system automatically deems backlight of the LCD and stop refrigerator (except at running) so that system reduces maximum 83% of standby electricity**.
  Just press a button, so you can contribute to the energy saving.

  

  • * comparing with standby electricity without Economy mode under in-house test condition.

Re-generative Converter for Braking

This product is equipped with the system that converts the regenerative power of the motor into power supply.
It converts the kinetic energy into electricity instead of heat when the rotor decelerates. This system can reduce the temperature rise in the room and return maximum 20%* of electricity used during the rotor acceleration to power supply.

• Depends on the type of rotor and rotation speed

Environment friendly design

CR22N is made with the environment-friendly design. Over 80% materials of the product are reusable or recyclable. It has reduced use of harmful substance in materials and components. Also refrigerant used in CR22N has ODP (ozone depletion potential) equals to 0.

Automatic rotor identification

This function automatically adjust optimized running condition based on the rotor automatically identified by compensating for air friction and implement temperature control etc.

Automatic rotor cover detector

It detects rotor cover status by ultrasonic sensor on the door. It prevents from unexpected accident caused by without rotor cover in advance.

Pre-cool function

• This function maintains temperature inside rotor chamber at 15 ℃ with preventing from icing, in order to reduce electricity consumption and reach target temperature faster, when the rotor is not sent on the drive shaft. When the rotor is set on the drive shaft, refrigerator controls the temperature inside the rotor chamber at the set temperature.

  

Zoom function

• Display of running speed and time is enlarged on the screen in order to find the operating status from a distance. Screen is switched from “Run Screen” to Zoom Display” automatically at 20 sec. after reaching the set speed.

  

User administration

• You can register up to 40 users into the memory. You can set access level and PIN of each user. There are two access levels, “Administration” or “User”. “Administrator” can access full function, while “User” cannot access administrator function when the user lockout function is on.

  

User Lockout Function

• User Lockout In case the user lockout function is enabled, only registered user can login the system by entering registered 4 digit PIN. It is useful function to control user access based on the groups or laboratories.

  

USB

• USB port is equipped as a standard specification. The system records up to 100 operating histories in its memory. The operating data can be output in CSV format thought the USB port.

  

LAN

Optional LAN board is also available. You can link CR22N to your PC through Ethernet or internet. Optional software “himac LogManager Ver.5.0 (network edition)” can be installed in your PC and operating history and data of CR22N can be easily managed by your PC.

himac LogManager Ver.5.0 for Windows® (Network Edition) – Optional log management software

himac LogManager Ver.5.0 for Windows® (Network Edition) is useful and covenant software to manage real time operating log of himac CP-NX series, CP-WX series, CS150NX, CS150FNX, CR30NX, CR7N and CR22N. Maximum 16 units of abovementioned centrifuges can be registered to the software at once. As data communication between the centrifuges and PC is done via LAN, so there is no distance limitation to establish a network. You can easily establish the network configuration and relocation with commercially available LAN devices. (Optional LAN board is required for the centrifuges.) It means you can manage the operation log at the different location from the installation sites of the centrifuges.
The software is real-time log management software; recording period is selectable from 10 seconds to 5 minutes interval. Of course, the software supports U.S. FDA 21 CFR Part 11, following functions are available;

• Digital signature
• Audit trail
• Encrypted data files etc.
