High Precision Temperature Control System : 

• The High Precision Microprocessor temperature control system and platinum resistor temperature sensors can realize more precise temperature control and enable users to set temperature inside the cabinet with a controllable range from -40°C to -86°C ensure the controlling precision ±1°C.
• The Large & Bright 2" LED digital temperature display, user-friendly interface and more accurate temperature control, which can indicate operating status clearly, temperature display simultaneously display the chamber temperature, Power Supply, Voltage, Ambient Temperature, Alarm and other parameters, etc,. The running status is clearly displayed and can be seen from distance.

Security  & Alarm System :

• It has a Multiple Audible & Visible Alarm functions, such as High / Low Temperature Alarm, Sensor Failure Alarm, Door Ajar Alarm, High Ambient Temperature Alarm, System Failure Alarm, Power Failure Alarm, Low Battery Alarm, Communication Failure Alarm, Samples out of date notification, Condenser cooling failure, etc,. 
• USB data storage function: can store relevant operating data, which can be downloaded and checked, ensuring improved security and reliability of sample storage.
• The turn-on delay and stopping interval protection can ensure reliable operation.
• The Lockable door, Keyboard Lock and Password protection prevents any unauthorized access and operation without permission.

Effective Thermal Insulation System :

• The Ultra Low temperature freezer is equipped with VIP+ vacuum insulation foaming door with seal. The two layer insulated foam door with double seal and the outdoor insulation design with multiple patents can prevent loss of cooling effectively and to improve temperature stability.
• The six sides of the cabinet are made from high-performance vacuum insulation materials, which can perfectly improve the thermal insulation performance.
• Individual inner door can be opened independently to minimize frost buildup and prevent loss of cooling inside the chamber. 

Powerful Refrigeration System :

• Ultra Low deep freezer is adopted high-efficiency hermetically sealed compressor and famous EMB fan, which are energy saving and environmentally friendly. 
• CFC / HCFC / HFC Free refrigerants
• The large finned condenser with a space between fins ≤ 2mm provides effective heat dissipation.
• Specialized refrigeration system design using whisper quiet fan and compressor ≤ 55dB  

Ergonomic Design :

• The interior are made of SS304 and Exterior is painted steel board low temperature resistance, anti-corrosion for long Service life and easy cleaning.
• The door with new type assisting rotating door handle and vacuum release port let the freezer be operated singlehanded to open and close the door easily.
• The two door design including the inner door and outer door can lock the cool air inside the chamber and ensures thermal insulation double silicon gasket seal for a long period. 
• Equipped with temperature printer, record 7days data. 72 hour battery back up for printer and controller display.
• 4 Universal Caster wheels, easy for movement.
• Optional : Chart Recorder, Printer, Rs485, RS232, Co2 Backup System, Storage Racks & Boxes, Remote Alarm system.
