7'' Screen Control System

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

·The high-precision microcomputer control system and platinum resistor sensors enable users to set the 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, provides 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battery, door ajar, main board communication error, high ambient temperature, built-in datalogger USB failure, samples out of date notification, etc;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 touchscreen controller and keyboard 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 plates, and the thermal insulation design of the inner door is made from foaming material. The outer door system was awarded multiple patents, which can improve the thermal insulation performance of the freezer.



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

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

·The liner made from 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.


Optional Accessory(WiFi/Bluetooth printer/Mechanical lock/Swipe card/Fingerprint)

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. Optional Bluetooth printer, real-time export temperature data, temperature graph, setting operation, and other data to understand the freezer operating status. Optional functions such as card, fingerprint, and facial recognition unlocking are available to facilitate quick sample access.
