Features of ultra-low temperature refrigerator
* Compact design,small footprint: large use space. Flexible installation and movement。
* Insulation: The four-layer insulation and sealing design, and the foamed inner door effectively prevent the air-conditioning from leaking when the door is opened normally;
* USB data storage function It can store temperature, voltage, open times and alarm data. At the same time, it can download the data and query the record through the computer, Can record more than 10 years
* Low noise design Dedicated noise reduction cabin design and hydrocarbon system design, using imported ultra-quiet hydrocarbon compressors and imported ultra-low noise energy-saving fans, with lower noise.
* No frosting: The unique five-layer sealing structure and heat insulation system design can effectively eliminate frosting.
* Hydrocarbon refrigeration system: the new ultra-quiet hydrocarbon refrigeration system, environmentally friendly and pollution-free, 30% energy saving, effective cost savings.
* Intelligent upgrade: Cold chain monitoring system and sample resource management information system can be selected to realize the upgrade of sample storage to sample safety management.
* Optional SMS treasure, can remotely monitor real-time working data and set the temperature in the box, or alarm in emergency
 
Function
* V.I.P. (Vacuum Insulation Panel) vacuum insulation technology
An advanced thermal insulation technology, which uses new high-vacuum insulation materials. No Freon is used to protect the environment. It is ensured that while sealing, the air between the insulation layers is taken away, so that the air heat conduction effect of the insulation material is reduced to a small, and the control of conduction, convection, radiation and other factors is exerted to the different state, thus achieving better insulation. Thermal insulation effect, while increasing storage space by 30%.

* Humanized design
1. The LED display can display box temperature, set temperature, ambient temperature, input voltage, set high and low temperature alarms and box temperature, and has a fault warning function;
2. Multi-layer shelf design with large capacity and convenient access to items;
3. Security door lock to prevent random opening Innovative integrated door lock handle and compact caster design, flexible and more convenient;
4. The condensing fan operates intelligently, effectively saving energy;
5. With network, remote alarm function and automatic high and low voltage compensation function
6. Freezer box and code lock are optional.

* Refrigerating system
1. Optimized cascade refrigeration technology, imported compressor, specially designed low temperature computer control, stronger refrigeration capacity;
2. Ultra-thick and high-density insulation layer with good insulation effect;
3. Unique five-way sealing structure and heat insulation system design, effectively eliminating frost;* Security

system
1. Multiple fault alarms (high and low temperature alarm, sensor alarm, high and low voltage alarm, condenser heat difference alarm, ambient temperature exceeding alarm); power failure alarm
2. Two alarm methods (sound buzzer alarm, light flashing alarm);
3. Multiple protection functions (password protection, boot delay protection, ultra-low voltage compensation protection, ultra-high voltage compensation protection);

* Temperature control 
Computer control, temperature digital display, adjustment unit is 1℃, the temperature inside the box is adjustable from -10℃~-86℃, and the accuracy is 0.1℃
