7’ Screen Control System

·7-inch Android HD display touch screen,user-friendly interface and more accurate temperature control, with Bluetooth, Wi-Fi and other functions, more convenient operation and more comprehensive functions;

·The high-precision microcomputer control system and platinum resistor sensors enable users to set temperature inside the cabinet within a range from -40 to -86℃.

Refrigeration System

·The imported high-efficiency compressor and EBM fan are energy-saving and highly efficient;

·The large finned condenser with a space between fins≤2mm, providing effective heat dissipation.

Security System

·The perfect audible & visual alarm system : high and low temperature ,sensor failure ,power

failure ,low battery ,door ajar ,main board communication error, high ambient temperature ,built-in datalogger USB failure,samples out of date notification etc;

·The compressor start delay and stopping interval protection can ensure reliable operation;

·Both the touch screen controller and key- board controller have password protection which can prevent any adjustment of operation without permission;

Three-dimensional Thermal Insulation

The six sides of the cabinet are made from high -efficiency VIP vacuum thermal insulation plate, and the thermal insulation design of the inner door made from foaming material and the outer door system was awarded with multiple patents, which can improve the thermal insulation performance of the freezer.


·The new designed assisting handle and vaccum release port let the freezer be operated single- handed to open and close the outer door.

·The newly added file box makes recording easier and more convenient.

·The liner made from galvanized steel sheet (optional stainless steel 304) for medical use is low- temperature tolerant and corrosion-resistant, which has a long service life and is easy to clean;

·The universal casters and leveling feet design are more convenient for movement and fixation.


Connect WiFi to upload data to the cloud space, monitor the device, check the status of the refrigerator faster, and ensure the safety of the samples.
