The built-in temperature monitoring and control circuitry keeps the temperature at a steady level of -45 to -50 degree Celsius at the nozzle. If the temperatures fall outside a predefined range, the system will automatically be shut down by the Cryo-Z control unit. The same control unit also pre-chills the system and automatically turns on the computer once a temperature of approximately -30 degree Celsius is reached
