• Ultra-Low Temperature Freezer, Upright Type

• Dual Compressor System
  - Two units of Compressor operate independently, freezer system structure simplified, decrease of failure rate
  - Cool-down temperature Implementation by Max -95°C
  - Fast temperature recovery through boost function
  - Eco Mode: cross-operating of the Compressor, reducing power consumption, and extending its life
• Exhaustive Backup System
  - In case one of the Compressors fails, the temperature maintains down to -80°C by the other Compressor
    (Dual Cooling System)
  - Each function conducts by operating temperature and alarm controllers independently
    even if one controller frails
  - Each function conducts by operating control and alarm sensors independently even if one sensor frails
  - Temperature monitoring and alarm functions conduct through an internal battery under power outages
  - Internal temperature maintains -60°C when the problem occurs through the CO2 backup system / Optional
• Auto-diagnose system and alarm system
  - Able to take action before the problem occurs through the Compressor, temperature sensor,
    and power supply observation function
  - Temperature leaving alarm, temperature sensor abnormal alarm, Compressor abnormal alarm,
    input voltage abnormal alarm, Door Open alarm, and machine room temperature alarm
  - Able to check the alarm outside in case of a problem occurs through Wi-Fi Monitoring System
• Auto Door (Optional, Except for UFS2083 model)
  - Automatic opening and shutting through the button on the controller
  - User record management function
  - Able to security maintenance through password entry function
• Condenser has no pin structure, so cleaning is not required and maintenance is convenient
• Negative pressure release function of the Door opening and shutting
• Temperature graph, even Log check and download function
• LK Labkorea
