·Freon-free refrigerant, compressor supplied by an international famous brand and EBM fan can guarantee fast cooling and are energy-saving and environmentally friendly;
·Refrigerating circuit with proprietary intellectual property rights ensures high efficiency and stability;
·Two-layer heat insulating foamed door and the insulation design of the outer door system with multiple patents can prevent loss of refrigerating capacity in an effective way;
·Six sides of the cabinet are made from high-performance vacuum insulation material, improving thermal insulation performance to a large extent.
High-precision microcomputer temperature control system and platinum resistor temperature sensors ensure more precise temperature control.
High-quality steel plate structure with phosphate coating, stainless steel liner and low noise design can create a comfortable environment.
1.The digital temperature display can show various parameters simultaneously, such as temperature inside the cabinet, power voltage and environmental temperature, indicating operating status clearly
2.The high-precision microcomputer temperature control system and platinum resistor temperature sensors enable users to set temperature inside the cabinet within a range from -20℃ to -40℃
3.The compressor supplied by an international famous brand and EBM fan is powerful, energy-saving and highly efficient The large-area finned condenser is characterized by a space equal to or less than 2mm between fins, providing a large area for heat dissipation and satisfactory performance
4.The two-layer heat insulating foamed door with airbag-typed outer seal and the insulation design of the outer door system with multiple patents can prevent loss of refrigerating capacity in an effective way The six sides of the cabinet are made from high-performance vacuum insulation material, improving thermal insulation performance to a large extent
5.The well-developed alarm system has multiple alarm functions: high temperature/low temperature alarm, door opening alarm, power outage alarm, abnormal voltage alarm, sensor failure alarm, low battery alarm, alarm of poor heat dissipation of condenser, system failure alarm, etc. The turn-on delay and stopping interval protection function can ensure reliability in running The keyboard lock function and password protection function can prevent any adjustment of operating parameters without permission
6.The rotating handle facilitates door opening The adjustable layered structure is convenient for storage of various things
7.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
